The bloom of Noctiluca Scintillans on Karnataka coast has displaced microscopic algaeThe bloom of Noctiluca Scintillans, commonly known as “sea sparkle” that the Karnataka coast has been witnessing since about a month, has displaced microscopic algae The non-toxic algae are common in the water off the Hong Kong coast, but its effects can be difficult to photograph: the glow only shows up when the water is disrupted. Its bioluminescence is produced throughout the cytoplasm of this single-celled protist, by a luciferin-luciferase reaction in thousands of spherically shaped organelles, called scintillons. Prof Hallegraeff, from the University of Tasmania, said it could also disrupt the food chain. 2. Mr Chatwin said he had not seen the algae near his home before. You can even see the digested algae cells as greenish flecks when you look at it under a microscope. Though the species does not produce a toxin, it was found to accumulate toxic levels of ammonia, which is then excreted into the surrounding waters, possibly acting as the killing agent in blooms.
