Aliivibrio fischeri is a Gram-negative, rod-shaped bacterium found globally in marine environments. A. fischeri has bioluminescent properties, and is found predominantly in symbiosis with various marine animals, such as the bobtail squid. It is heterotrophic and moves by means of flagella. Free-living A. fischeri survive on decaying organic matter (see saprotroph). The bacterium is a key research organism for examination of microbial bioluminescence, quorum sensing, and bacterial-animal symbiosis. It is named in honor of Bernhard Fischer, a German microbiologist.
rRNA comparison led to the reclassification of this species from genus Vibrio to the newly created Aliivibrio in 2007.
