''Vibrio campbellii'' is a Gram-negative, curved rod-shaped, marine bacterium closely related to its sister species, ''Vibrio harveyi''. It is an emerging pathogen in aquatic organisms. ==Biology== Quorum sensing allows the bacterium to communicate with autoinducers, a chemical signaling molecule that is secreted. Some strains of ''V. campellii'' are known to be not luminescent; these strains are thought to be less virulent than the luminescent strains. Bioluminescence in bacteria is due to the reaction: FMNH− + H+ + RCHO + O2 → FMN + RCOOH + H2O + hν and is catalyzed by the enzyme luciferase. A new luciferase was isolated from ''V. campbellii'' (Lux_Vc) and is similar to that of the Lux_Vh found in ''V. harveyi'', but is more thermodynamically stable due to the binding of reduced FMN. The ''V. campbellii'' strains PEL22A, BAA-1116, AND4 are known to be mixotrophic or more specifically photo(organo)heterotrophic. This is considered a rare phenotype in ''Vibrio'' and is thought to be caused by their exploitation of lateral gene transfer during adaptation. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Vibrio campbellii」の詳細全文を読む スポンサード リンク
