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
Noctiluca scintillans, a bioluminescent dinoflagellate. Bioluminescence is the production of light by living organisms. This list of bioluminescent organisms is organized by the environment, covering terrestrial, marine, and microorganisms.
Dinoflagellate blooms are generally unpredictable, short, with low species diversity, and with little species succession. [73] The low species diversity can be due to multiple factors. One way a lack of diversity may occur in a bloom is through a reduction in predation and a decreased competition.
It is a marine dinoflagellate commonly found in the waters of the Gulf of Mexico. [1] It is the organism responsible for the "Florida red tides" that affect the Gulf coasts of Florida and Texas in the U.S., and nearby coasts of Mexico. K. brevis has been known to travel great lengths around the Florida peninsula and as far north as the ...
The structure of the dinoflagellate luciferase catalytic domain has been solved. [10] The core part of the domain is a 10 stranded beta barrel that is structurally similar to lipocalins and FABP. [10] The N-terminal domain is conserved between dinoflagellate luciferase and luciferin binding proteins (LBPs).
Fluorescence in several wavelengths can be detected by an array detector, to detect compounds from HPLC flow. Also, TLC plates can be visualized if the compounds or a coloring reagent is fluorescent. Fluorescence is most effective when there is a larger ratio of atoms at lower energy levels in a Boltzmann distribution. There is, then, a higher ...
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.
Pyrodinium have caused more human illnesses and fatalities than any other dinoflagellates that cause Paralytic Shellfish Toxin or PST. [4] It was initially widely believed that the compressum variety was toxic and found in the Pacific while the bahamense variety was nontoxic and found in the Atlantic, but a 1972 toxic algal bloom of Pyrodinium bahamense in Papua New Guinea [5] showed this was ...
