The colonies have very interesting and diverse morphology, forming spherical (round) colonies composed of many cells or occurring as straight or branched filaments (long, thin series of cells). Diatoms are unicellular algae with plastids acquired by secondary endosymbiosis. Once these bodies are formed, they are cleaved into uni-nucleate single cells that then burst and begin life as individual organisms.Â. The polysaccharides of this species are sulphated and their structure gives rise to some unique properties that could lead to a broad range of industrial and pharmaceutical applications. This is one of the ONLY red microalgae strains. Microalgae are unicellular and contain all necessary metabolic processes within one membrane, whereas macroalgae more closely approximate land plants as they are composed of vascular and root systems. These grains surround the pyrenoid, an organelle within an organelle that assists the chloroplast with the concentration of carbon dioxide used to create sugars during photosynthesis. They can be found in colonies up to 64 cells or on their own. Learn more about Chlorella, About the Algae: Chlorella pyrenoidosa is a eukaryotic, unicellular green algae that inhabits freshwater environments.  They are prokaryotic and have no membrane-bound organelles.

They are most commonly found in alkaline aquatic environments (but also in aquatic environments ranging in salinity and acidity), they can also be found in soil, on rocks, and even in the atmosphere. Bacillariophytes, or diatoms, are single-celled algae that have silica shells (frustules) with very intricate patterns and symmetrical shapes. In nutrient-saturated environments, diatoms are generally the most abundant phytoplankton and serve as an important food source for aquatic life in both fresh and saltwater environments. Thylakoids, or the structures inside chloroplasts that perform photosynthesis, weave between the pyrenoids of Tetraselmis to facilitate the transport of intermediate molecules. Introduction to Algae and Aquatic Science, Algae Experiments, Ideas, and Lesson Plans, Pigments include Chlorophylls -a and -d and the red pigment phycoerytherin, Cell walls are composed of cellulose or pectin, many strains can produce calcium carbonate structures similar to coralsÂ. The cell walls of coralline red algae become heavily encrusted with calcium carbonate.Â. When a zooplankton predator takes a mouthful of glowing dinos, it is likely to spit them right back out rather than risk glowing itself.  Otherwise, it might be seen by a bigger (more opaque) predator and become fish food. 13(4): 284-291. Due to the ongoing effects of climate change, phytoplankton are likely to experience enhanced irradiance, more reduced nitrogen, and increased water acidity in the future ocean. In fact, these dinoflagellates glow using the same mechanism as a firefly despite their evolutionary distance. This genera comprise the largest of the centric diatoms with more than 100 species described. They can be identified by their characteristic shape: box shaped, cylindrical, drum shaped, discoid, and coin shaped. They are from the genus Chlorella, a long-studied chlorophyte algae with an incredibly inventive name derived from the Greek “chlor” (green) and the Latin “ella” (small). Chlorella cells in general have a spherical cell body with a diameter of 2-10 micrometers and contain a single, cup-shaped chloroplast. Schone, H. 1974. A few also occur in freshwater. These grains surround the pyrenoid, an organelle within an organelle that assists the chloroplast with the concentration of carbon dioxide used to create sugars during photosynthesis. They can be found in colonies up to 64 cells or on their own. Learn more about Chlorella, C. pyrenoidosa Starter Culture: coming soon!Â, About the Algae: Eulgena are a genus of freshwater unicellular flagellated green algae in the class Euglenoidea. Protein sets from fully sequenced genomes. Only 20 top taxa will be shown. It contains the pigment phycocyanin, which is a water soluble photosynthetic protein. Individual Spriulina cells form beautiful spiral morphologies called "tricomes. About the Algae: Isochrysis galbana is a great feeder algae. It is covered in a thick wall composed of a series of fused plates made of carbohydrates, termed a “theca.” Tetraselmis usually possesses a single cup-shaped chloroplast enclosing a pyrenoid, or special sub-organelle used in the carbon concentration mechanism (CCM). Experimental investigations on the ecology of the. The purpose of these bristles is thought to be related to predator defense. This stage is often the immediate product of reproduction in which the cell can split through meiosis multiple times before bursting from the mother cell wall, resulting in 4 to 8 daughter cells. ARS provides microalgal cultures as they are the quintessential algal morphotype and possess high growth rates, simple life cycles and are the simplest species to culture. This organelle helps expel freshwater from the cytoplasm and regulate the concentration of dissolved solutes in the cell. Some species of dinoflagellates, including Pyrocystis fusiformis, emit bright flashes of light called bioluminescence when disturbed. Originally isolated in 1945, this species is a model organism for a variety of questions in cell and molecular biology, including the mechanics of flagellar-based motility and phototaxis. In most cases, commonly described algae are unicellular phytoplankton, which means they are photosynthetic, single-celled organisms that live freely and suspended in the water they inhabit. The casual observer can view them as large (macro) or small (micro). Recent genetic analyses have suggested that certain green algae are evolutionarily closer to land plants than they are to red or brown aquatic algae! Certain diatoms can also form harmful or noxious algal blooms: Albert Hitchcock'sÂ,  are a genus of centric diatom and primarily grow in marine waters. Cyclotella Starter Culture: coming soon! The etymology of its name refers to the flat swimming legs of the copepod (Mauchline 1998).Copepods have long been recognized as a suitable food for marine fishes, especially for those in first-feeding larval stages. The reproductive life history of Scenedesmus is also interesting, comprised of a single cell that forms multi-nucleate bodies within a single cell wall. Green algae are thought to be in the evolutionary line that gave rise to the first land plants and are often called grass-green algae because of the similarities in pigments to terrestrial plants. Cyanobacteria have a wide variety of habitats that range from frozen lakes, to acidic bogs, to deserts and volcanoes. The pyrenoid is surrounded by a wall of starch granules and mostly made up of the enzyme RuBisCO, which accepts carbon dioxide sourced from the atmosphere and transforms it into the first chemical step in the pathway used by algae to create the complex sugars they need for respiration. C. reinhardtii Culture Kit: coming soon!Â, About the Algae: Chlorella vulgaris is a eukaryotic, unicellular green algae that inhabits freshwater environments. doi: 10.1007/BF00353582. Thylakoids, or the structures inside chloroplasts that perform photosynthesis, weave between the pyrenoids of, to facilitate the transport of intermediate molecules. We know when it is happy and healthy because when you smell it, it smells like low tide! The high lipid and DHA content make it popular as an aquaculture feed for animals such as bivalves, crustaceans, and zooplankton. Saltwater reef aquarium hobbyists love this strain as it brings great pigmentation to the corals. In the dark ocean, it is advantageous to avoid being seen. It is covered in a thick wall composed of a series of fused plates made of carbohydrates, termed a “theca.” Tetraselmis usually possesses a single cup-shaped chloroplast enclosing a pyrenoid, or special sub-organelle used in the carbon concentration mechanism (CCM). Phycocyanin is a protein that functions as the photosynthetic pigment in photosystem II, whereas in plants chlorophyll b is the pigment in photosystem II. It's hypothesized that the reason dinoflagellates evolved the ability to glow at all was to avoid being eaten (much to the contrary of fireflies, which flash in intricate patterns to attract a mate). Scenedesumus Starter Culture: coming soon!  Cyanobacteria gets its common name from the blue-green pigment, phycocyanin, which along with chlorophyll a gives cyanobacteria a blue-green appearance. The word “copepod” originates from the Greek words “kope”, an oar, and “podos”, a foot. Diatomaceous earth is a deposit of fossilized diatoms; diatoms frustules give these deposits a wide range of commercial like “natural” pest control, cosmetic abrasives, and water filtration. They are from the genus Chlorella, a long-studied chlorophyte algae with an incredibly inventive name derived from the Greek “chlor” (green) and the Latin “ella” (small). Chlorella cells in general have a spherical cell body with a diameter of 2-10 micrometers and contain a single, cup-shaped chloroplast. When coccolithophores die, they sink to the bottom of the ocean where their plates form carbonate oozes, contribute to sediment, and create limestone and chalk. Haptophytes are another clade of photosynthetic unicellular algae, containing fucoxanthin and diadinoxanthin to give them a golden-brown color.

They are most commonly found in alkaline aquatic environments (but also in aquatic environments ranging in salinity and acidity), they can also be found in soil, on rocks, and even in the atmosphere. Bacillariophytes, or diatoms, are single-celled algae that have silica shells (frustules) with very intricate patterns and symmetrical shapes. In nutrient-saturated environments, diatoms are generally the most abundant phytoplankton and serve as an important food source for aquatic life in both fresh and saltwater environments. Thylakoids, or the structures inside chloroplasts that perform photosynthesis, weave between the pyrenoids of Tetraselmis to facilitate the transport of intermediate molecules. Introduction to Algae and Aquatic Science, Algae Experiments, Ideas, and Lesson Plans, Pigments include Chlorophylls -a and -d and the red pigment phycoerytherin, Cell walls are composed of cellulose or pectin, many strains can produce calcium carbonate structures similar to coralsÂ. The cell walls of coralline red algae become heavily encrusted with calcium carbonate.Â. When a zooplankton predator takes a mouthful of glowing dinos, it is likely to spit them right back out rather than risk glowing itself.  Otherwise, it might be seen by a bigger (more opaque) predator and become fish food. 13(4): 284-291. Due to the ongoing effects of climate change, phytoplankton are likely to experience enhanced irradiance, more reduced nitrogen, and increased water acidity in the future ocean. In fact, these dinoflagellates glow using the same mechanism as a firefly despite their evolutionary distance. This genera comprise the largest of the centric diatoms with more than 100 species described. They can be identified by their characteristic shape: box shaped, cylindrical, drum shaped, discoid, and coin shaped. They are from the genus Chlorella, a long-studied chlorophyte algae with an incredibly inventive name derived from the Greek “chlor” (green) and the Latin “ella” (small). Chlorella cells in general have a spherical cell body with a diameter of 2-10 micrometers and contain a single, cup-shaped chloroplast. Schone, H. 1974. A few also occur in freshwater. These grains surround the pyrenoid, an organelle within an organelle that assists the chloroplast with the concentration of carbon dioxide used to create sugars during photosynthesis. They can be found in colonies up to 64 cells or on their own. Learn more about Chlorella, C. pyrenoidosa Starter Culture: coming soon!Â, About the Algae: Eulgena are a genus of freshwater unicellular flagellated green algae in the class Euglenoidea.

About the Algae: Isochrysis galbana is a great feeder algae. It is covered in a thick wall composed of a series of fused plates made of carbohydrates, termed a “theca.” Tetraselmis usually possesses a single cup-shaped chloroplast enclosing a pyrenoid, or special sub-organelle used in the carbon concentration mechanism (CCM). Experimental investigations on the ecology of the. The purpose of these bristles is thought to be related to predator defense. This stage is often the immediate product of reproduction in which the cell can split through meiosis multiple times before bursting from the mother cell wall, resulting in 4 to 8 daughter cells. ARS provides microalgal cultures as they are the quintessential algal morphotype and possess high growth rates, simple life cycles and are the simplest species to culture. This organelle helps expel freshwater from the cytoplasm and regulate the concentration of dissolved solutes in the cell. Some species of dinoflagellates, including Pyrocystis fusiformis, emit bright flashes of light called bioluminescence when disturbed. Originally isolated in 1945, this species is a model organism for a variety of questions in cell and molecular biology, including the mechanics of flagellar-based motility and phototaxis. In most cases, commonly described algae are unicellular phytoplankton, which means they are photosynthetic, single-celled organisms that live freely and suspended in the water they inhabit. The casual observer can view them as large (macro) or small (micro). Recent genetic analyses have suggested that certain green algae are evolutionarily closer to land plants than they are to red or brown aquatic algae! Certain diatoms can also form harmful or noxious algal blooms: Albert Hitchcock'sÂ,  are a genus of centric diatom and primarily grow in marine waters. Cyclotella Starter Culture: coming soon! The etymology of its name refers to the flat swimming legs of the copepod (Mauchline 1998).Copepods have long been recognized as a suitable food for marine fishes, especially for those in first-feeding larval stages. The reproductive life history of Scenedesmus is also interesting, comprised of a single cell that forms multi-nucleate bodies within a single cell wall. Green algae are thought to be in the evolutionary line that gave rise to the first land plants and are often called grass-green algae because of the similarities in pigments to terrestrial plants. Cyanobacteria have a wide variety of habitats that range from frozen lakes, to acidic bogs, to deserts and volcanoes. The pyrenoid is surrounded by a wall of starch granules and mostly made up of the enzyme RuBisCO, which accepts carbon dioxide sourced from the atmosphere and transforms it into the first chemical step in the pathway used by algae to create the complex sugars they need for respiration. C. reinhardtii Culture Kit: coming soon!Â, About the Algae: Chlorella vulgaris is a eukaryotic, unicellular green algae that inhabits freshwater environments. doi: 10.1007/BF00353582.

We know when it is happy and healthy because when you smell it, it smells like low tide! The high lipid and DHA content make it popular as an aquaculture feed for animals such as bivalves, crustaceans, and zooplankton. Saltwater reef aquarium hobbyists love this strain as it brings great pigmentation to the corals. In the dark ocean, it is advantageous to avoid being seen. It is covered in a thick wall composed of a series of fused plates made of carbohydrates, termed a “theca.” Tetraselmis usually possesses a single cup-shaped chloroplast enclosing a pyrenoid, or special sub-organelle used in the carbon concentration mechanism (CCM). Phycocyanin is a protein that functions as the photosynthetic pigment in photosystem II, whereas in plants chlorophyll b is the pigment in photosystem II. It's hypothesized that the reason dinoflagellates evolved the ability to glow at all was to avoid being eaten (much to the contrary of fireflies, which flash in intricate patterns to attract a mate). Scenedesumus Starter Culture: coming soon!  Cyanobacteria gets its common name from the blue-green pigment, phycocyanin, which along with chlorophyll a gives cyanobacteria a blue-green appearance. The word “copepod” originates from the Greek words “kope”, an oar, and “podos”, a foot. Diatomaceous earth is a deposit of fossilized diatoms; diatoms frustules give these deposits a wide range of commercial like “natural” pest control, cosmetic abrasives, and water filtration. They are from the genus Chlorella, a long-studied chlorophyte algae with an incredibly inventive name derived from the Greek “chlor” (green) and the Latin “ella” (small). Chlorella cells in general have a spherical cell body with a diameter of 2-10 micrometers and contain a single, cup-shaped chloroplast. When coccolithophores die, they sink to the bottom of the ocean where their plates form carbonate oozes, contribute to sediment, and create limestone and chalk. Haptophytes are another clade of photosynthetic unicellular algae, containing fucoxanthin and diadinoxanthin to give them a golden-brown color.

thalassiosira pseudonana common name

Artemia is a genus of aquatic crustaceans also known as brine shrimp.  Artemia are able to avoid most types of predators, such as fish, by their ability to live in waters of very high salinity 250grams per liter. Schone, H. 1972. [1] T. pseudonana was selected for this study because it is a model for diatom physiology studies, belongs to a genus widely distributed throughout the world's oceans, and has a relatively small genome at 34 mega base pairs . "  Â. Dinoflagellates, have two flagella used for locomotion, one around their thallus like a belt, and the other at their bottom. Thalassiosira pseudonana About the Algae: Thalassiosira are a genus of centric diatom and primarily grow in marine waters. It's hypothesized that the reason dinoflagellates evolved the ability to glow at all was to avoid being eaten (much to the contrary of fireflies, which flash in intricate patterns to attract a mate). Unlike most other algae mentioned in this list Scenedesmus is exclusively colonial, comprising multiple linked cells that terminate in spiked bristles. The name: other Thalassiosiraceae spp. There are currently 74 accepted species within the genus, although the degree of sub-generic diveristy suggests that a reclassification of the genus may be coming soon. A species of Thalassiosira, T. pseudonana, was selected as the first marine eukaryotic phytoplankton to undergo whole genome sequencing, due to its small 34Mb genome. Copepods are small aquatic crustaceans that are one of the most abundant multicellular animals on Earth. Diatoms can either live as individual cells or linked in chains up to hundreds of cells long. Analysis of phylogenetic relationship of Thalassiosira pseudonana genes Phylogenetic analysis of enzymes involved in the transacetylation of homoserine An interesting feature of T. pseudonana genome is that it contains next to the identified homoserine kinase a gene encoding a protein with high similarity to homoserine acetyltransferase (HAT; Thaps3: 12141). Under normal circumstances, however, they are a great source of food for marine life. Please consider upgrading,

(2009) Primary carbon and nitrogen metabolic gene expression in the diatom Thalassiosira pseudonana (Bacillariophyceae): Diel periodicity and effects of …  This is believed to 'blind' a predator, or if the predator eats the cell, the bioluminescence will light up the predator exposing it predation by a larger organism. Some species contain a red pigment phycoerythrine; others range in color from green to red, purple, and greenish-black. As a result, T. pseudonana has served as a model organism for understanding diatom biology. Blue-green algae make up the division Cyanophyta in the kingdom Eubacteria. Consequently, copepods have become a favorable source of feed in aquaculture (Marcus 2007).  The larger species have filaments that are massed together and resemble the leaves and stems of plants. To a trained microscopist, other readily recognized features such as strutted, occluded, and labiate processes can further distinguish specific Thalassiosira species. Cells can be found as individual bodies or in chain colonies connected by organic threads. Introduction In diatoms, the transition of the photosynthetic apparatus from a light harvesting to a photoprotective state is characterized by the non-photochemical quenching (NPQ) of chlorophyll (Chl) a fluorescence, and the cycling of electrons around photosystem II (PSII) and/or photosystem I (PSI) (Lavaud et al., 2002,a, b, 2004; Wilhelm et al., 2006). When P. fusiformis bloom in nature, they’re bright enough to bedazzle the entire surf break with pinpricks of eerie blue-green light.  In fact, tourists flock to bioluminescent dinoflagellate hotspots, like Mosquito Bay, Puerto Rico, where you can swim and kayak in the luminous glow.

These grains surround the pyrenoid, an organelle within an organelle that assists the chloroplast with the concentration of carbon dioxide used to create sugars during photosynthesis. They can be found in colonies up to 64 cells or on their own. Learn more about Chlorella, About the Algae: Chlorella pyrenoidosa is a eukaryotic, unicellular green algae that inhabits freshwater environments.  They are prokaryotic and have no membrane-bound organelles. Most species are cosmopolitan, or able to exist in a variety of marine environments around the world. Named for its four flagella arranged in two opposite pairs (“tetra” = four, “selmis” = an angler’s noose made of hair), this motile algae is cordiform (heart-shaped) with an invagination located where flagella emerge from the cell. Experimental investigations on the ecology of the marine diatom Thalassiosira rotula. While they can be found in fresh and brackish waters,  species have been shown to be suitable for algal biofuel production and isÂ, popular for use in aquaculture feed and dietary supplements.Â, is a green alga genus of eukaryotic marine and freshwater phytoplankton. Systems used to automatically annotate proteins with high accuracy: Select one of the options below to target your search: Select item(s) and click on "Add to basket" to create your own collection here (400 entries max). They are most commonly found in alkaline aquatic environments (but also in aquatic environments ranging in salinity and acidity), they can also be found in soil, on rocks, and even in the atmosphere. Bacillariophytes, or diatoms, are single-celled algae that have silica shells (frustules) with very intricate patterns and symmetrical shapes. In nutrient-saturated environments, diatoms are generally the most abundant phytoplankton and serve as an important food source for aquatic life in both fresh and saltwater environments. Thylakoids, or the structures inside chloroplasts that perform photosynthesis, weave between the pyrenoids of Tetraselmis to facilitate the transport of intermediate molecules. Introduction to Algae and Aquatic Science, Algae Experiments, Ideas, and Lesson Plans, Pigments include Chlorophylls -a and -d and the red pigment phycoerytherin, Cell walls are composed of cellulose or pectin, many strains can produce calcium carbonate structures similar to coralsÂ. The cell walls of coralline red algae become heavily encrusted with calcium carbonate.Â. When a zooplankton predator takes a mouthful of glowing dinos, it is likely to spit them right back out rather than risk glowing itself.  Otherwise, it might be seen by a bigger (more opaque) predator and become fish food. 13(4): 284-291. Due to the ongoing effects of climate change, phytoplankton are likely to experience enhanced irradiance, more reduced nitrogen, and increased water acidity in the future ocean. In fact, these dinoflagellates glow using the same mechanism as a firefly despite their evolutionary distance. This genera comprise the largest of the centric diatoms with more than 100 species described. They can be identified by their characteristic shape: box shaped, cylindrical, drum shaped, discoid, and coin shaped. They are from the genus Chlorella, a long-studied chlorophyte algae with an incredibly inventive name derived from the Greek “chlor” (green) and the Latin “ella” (small). Chlorella cells in general have a spherical cell body with a diameter of 2-10 micrometers and contain a single, cup-shaped chloroplast. Schone, H. 1974. A few also occur in freshwater. These grains surround the pyrenoid, an organelle within an organelle that assists the chloroplast with the concentration of carbon dioxide used to create sugars during photosynthesis. They can be found in colonies up to 64 cells or on their own. Learn more about Chlorella, C. pyrenoidosa Starter Culture: coming soon!Â, About the Algae: Eulgena are a genus of freshwater unicellular flagellated green algae in the class Euglenoidea. Protein sets from fully sequenced genomes. Only 20 top taxa will be shown. It contains the pigment phycocyanin, which is a water soluble photosynthetic protein. Individual Spriulina cells form beautiful spiral morphologies called "tricomes. About the Algae: Isochrysis galbana is a great feeder algae. It is covered in a thick wall composed of a series of fused plates made of carbohydrates, termed a “theca.” Tetraselmis usually possesses a single cup-shaped chloroplast enclosing a pyrenoid, or special sub-organelle used in the carbon concentration mechanism (CCM). Experimental investigations on the ecology of the. The purpose of these bristles is thought to be related to predator defense. This stage is often the immediate product of reproduction in which the cell can split through meiosis multiple times before bursting from the mother cell wall, resulting in 4 to 8 daughter cells. ARS provides microalgal cultures as they are the quintessential algal morphotype and possess high growth rates, simple life cycles and are the simplest species to culture. This organelle helps expel freshwater from the cytoplasm and regulate the concentration of dissolved solutes in the cell. Some species of dinoflagellates, including Pyrocystis fusiformis, emit bright flashes of light called bioluminescence when disturbed. Originally isolated in 1945, this species is a model organism for a variety of questions in cell and molecular biology, including the mechanics of flagellar-based motility and phototaxis. In most cases, commonly described algae are unicellular phytoplankton, which means they are photosynthetic, single-celled organisms that live freely and suspended in the water they inhabit. The casual observer can view them as large (macro) or small (micro). Recent genetic analyses have suggested that certain green algae are evolutionarily closer to land plants than they are to red or brown aquatic algae! Certain diatoms can also form harmful or noxious algal blooms: Albert Hitchcock'sÂ,  are a genus of centric diatom and primarily grow in marine waters. Cyclotella Starter Culture: coming soon! The etymology of its name refers to the flat swimming legs of the copepod (Mauchline 1998).Copepods have long been recognized as a suitable food for marine fishes, especially for those in first-feeding larval stages. The reproductive life history of Scenedesmus is also interesting, comprised of a single cell that forms multi-nucleate bodies within a single cell wall. Green algae are thought to be in the evolutionary line that gave rise to the first land plants and are often called grass-green algae because of the similarities in pigments to terrestrial plants. Cyanobacteria have a wide variety of habitats that range from frozen lakes, to acidic bogs, to deserts and volcanoes. The pyrenoid is surrounded by a wall of starch granules and mostly made up of the enzyme RuBisCO, which accepts carbon dioxide sourced from the atmosphere and transforms it into the first chemical step in the pathway used by algae to create the complex sugars they need for respiration. C. reinhardtii Culture Kit: coming soon!Â, About the Algae: Chlorella vulgaris is a eukaryotic, unicellular green algae that inhabits freshwater environments. doi: 10.1007/BF00353582. Thylakoids, or the structures inside chloroplasts that perform photosynthesis, weave between the pyrenoids of, to facilitate the transport of intermediate molecules. We know when it is happy and healthy because when you smell it, it smells like low tide! The high lipid and DHA content make it popular as an aquaculture feed for animals such as bivalves, crustaceans, and zooplankton. Saltwater reef aquarium hobbyists love this strain as it brings great pigmentation to the corals. In the dark ocean, it is advantageous to avoid being seen. It is covered in a thick wall composed of a series of fused plates made of carbohydrates, termed a “theca.” Tetraselmis usually possesses a single cup-shaped chloroplast enclosing a pyrenoid, or special sub-organelle used in the carbon concentration mechanism (CCM). Phycocyanin is a protein that functions as the photosynthetic pigment in photosystem II, whereas in plants chlorophyll b is the pigment in photosystem II. It's hypothesized that the reason dinoflagellates evolved the ability to glow at all was to avoid being eaten (much to the contrary of fireflies, which flash in intricate patterns to attract a mate). Scenedesumus Starter Culture: coming soon!  Cyanobacteria gets its common name from the blue-green pigment, phycocyanin, which along with chlorophyll a gives cyanobacteria a blue-green appearance. The word “copepod” originates from the Greek words “kope”, an oar, and “podos”, a foot. Diatomaceous earth is a deposit of fossilized diatoms; diatoms frustules give these deposits a wide range of commercial like “natural” pest control, cosmetic abrasives, and water filtration. They are from the genus Chlorella, a long-studied chlorophyte algae with an incredibly inventive name derived from the Greek “chlor” (green) and the Latin “ella” (small). Chlorella cells in general have a spherical cell body with a diameter of 2-10 micrometers and contain a single, cup-shaped chloroplast. When coccolithophores die, they sink to the bottom of the ocean where their plates form carbonate oozes, contribute to sediment, and create limestone and chalk. Haptophytes are another clade of photosynthetic unicellular algae, containing fucoxanthin and diadinoxanthin to give them a golden-brown color.
