Bioluminescent bacteria are light-producing bacteria that are predominantly present in sea water, marine sediments, the surface of decomposing fish and in the gut of marine animals. While not as common, bacterial bioluminescence is also found in terrestrial and freshwater bacteria. [ 1 ]
The bioluminescence can be produced from compounds during the digestion of prey, from specialized mitochondrial cells in the organism called photocytes ("light producing" cells), or, similarly, associated with symbiotic bacteria in the organism that are cultured.
Bioluminescence is the emission of light during a chemiluminescence reaction by living organisms. [1] Bioluminescence occurs in diverse organisms ranging from marine vertebrates and invertebrates, as well as in some fungi, microorganisms including some bioluminescent bacteria, dinoflagellates and terrestrial arthropods such as fireflies.
A photocyte is a cell that specializes in catalyzing enzymes to produce light (bioluminescence). [1] Photocytes typically occur in select layers of epithelial tissue, functioning singly or in a group, or as part of a larger apparatus (a photophore). They contain special structures called photocyte granules.
Marine dinoflagellates at night can emit blue light by bioluminescence, a process also called "the phosphorescence of the seas". Light production in these single celled organisms is produced by small structures in the cytoplasm called scintillons. Among bioluminescent organisms, only dinoflagellates have scintillons.
L-luciferin is able to emit a weak light even though it is a competitive inhibitor of D-luciferin and the bioluminescence pathway. [13] Light is emitted because the CoA synthesis pathway can be converted to the bioluminescence reaction by hydrolyzing the final product via an esterase back to D-luciferin. [3]
Bioluminescence is a chemical reaction regulated by a gene or bacteria that enables living organisms to produce light naturally. Over 90 percent of marine organisms are bioluminescent -- algae ...
Bioluminescence occurs when an organism emits light through a chemical reaction [8] with the majority of the world's bioluminescent organisms living in the ocean. [9] The production of bioluminescence by P. fusiformis is thought to be a defense mechanism that startles grazers which would otherwise eat them [5] or to illuminate grazers so that they, in turn may be more visible to their own ...
