Marine luminous bacteria

heterotrophic bacteria give out visible light in normal physiological condition. Many study results show that the luminescence mechanisms of variety luminous bacteria are the same. The light-emitting in bacteria involves the oxidation of reduced riboflavin phosphate (FMNH

2

) and a long-chain fatty aldehyde with the emission of blue-green light. The enzymes that catalyze the bioluminescence reaction in these organisms are called luciferases

and in most cases the substrates are designated as luciferins. However

consistent with the apparent absence of strong evolutionary relationship between many of the light-emitting systems

significant differences exist between the bioluminescence reactions as well as the structures of the luciferases (enzymes) and luciferins (substrates) from different organisms. The luminescent characte-ristics of marine luminous bacteria connect with material structure in the bacteria

marine environment elements and pollutants in the seawater etc

the connect study includes that spectrum property

light-emitting intensity

light-emitting characteristic parameter

light-emitting conditions and the structure of luciferases from different luminous bacteria. Thorough understanding these properties of marine luminous bacteria and carrying out the study of application can supply effective methods for the application of the property of marine luminous bacteria

and promote comprehensive researches on ocean biology

ocean optics and biochemistry

and show the feasibility of physics researches on marine luminous bacteria. And the predictions show the concentration and toxicity of pollutants in the water is determined by luminescent intensity of luminous bacteria

the submarine sailing exits the whirlpool and the luminescent bacteria bioluminescent makes the whirlpool to be a ray track which can be used to detect submarine

the luminescent characteristics can also be used to improve in the under water light communications and exploring

ocean water color remote sensing

bacterial classification bioluminescent immunity and antibiotic concentration determination etc. In this article

important significance of the study on luminescent characteristic of marine luminous bacteria was clarified and reference is given for further developing.
