The name scintillon was first used to describe cytoplasmic particles isolated from a bioluminescent species of dinoflagellate that were able to produce a flash of light in response to a decrease in pH. [4] Scintillons were first observed in L. polyedra by fluorescence microscopy, [5] where
English-language taxonomic monographs covering large numbers of species are published for the Gulf of Mexico, [45] the Indian Ocean, [46] the British Isles, [47] the Mediterranean [48] and the North Sea. [49] The main source for identification of freshwater dinoflagellates is the Süsswasser Flora. [50]
Luminescent dinoflagellate ecosystems are present in warm water lagoons and bays with narrow openings to the ocean. [42] A different effect is the thousands of square miles of the ocean which shine with the light produced by bioluminescent bacteria, known as mareel or the milky seas effect .
Noctiluca scintillans is a marine species of dinoflagellate that can exist in a green or red form, depending on the pigmentation in its vacuoles.It can be found worldwide, but its geographical distribution varies depending on whether it is green or red.
Dinoflagellates are microbial eukaryotes that link bioluminesce and toxin production in algal blooms. [39] They use a luciferin-luciferase reaction to create a blue light emission glow. [ 40 ] There are seventeen major types of dinoflagellate toxins, in which the strains, Saxitoxin and Yessotoxin, are both bioluminescent and toxic.
A light micrograph of an ocelloid-containing dinoflagellate. The nucleus is marked n, the ocelloid is indicated with a double arrowhead, and a posterior cell extension is indicated with an arrow; scale bar = 10 μm. [1]
Due to longstanding pushback and controversial health studies surrounding the ingredient, many processed food manufacturers have already shifted away from using Red Dye No. 3, opting instead for ...
Pyrocystis fusiformis is a non-motile, tropical, epipelagic, marine dinoflagellate (flagellate microorganisms), reaching lengths of up to 1 millimetre (0.039 in). P. fusiformis display bioluminescence when disturbed or agitated. In coastal marine waters, this dinoflagellate causes glowing effects after dark.
