Aliivibrio fischeri ES114

Aliivibrio fischeri ES114 is a Gram-negative, rod-shaped bacterium that exhibits a facultative anaerobic metabolism, allowing it to thrive in various environments. This organism is classified as a heterotroph, utilizing organic compounds as its energy source. It has a unique cellular arrangement characterized by single cells and possesses flagella, indicating motility potential. However, it is noted to be immobile in specific contexts. A. fischeri ES114 is mesophilic, with an optimal growth temperature of 20°C, indicating that it thrives in moderate temperature conditions. This bacterium contains three replicons and is surrounded by two membranes, which is typical of Gram-negative bacteria. One of the notable traits of A. fischeri ES114 is its symbiotic relationship with marine organisms, particularly in association with the Hawaiian bobtail squid, Euprymna scolopes. This symbiosis is significant as it plays a crucial role in bioluminescence, aiding the squid in camouflage against predators. The presence of A. fischeri in the light organs of the squid not only highlights the ecological importance of this bacterium but also underscores the intricate relationships formed between microorganisms and their hosts in marine ecosystems. The accessions for A. fischeri ES114 include NC_006840.2, NC_006841.2, and NC_006842.1, which provide genomic information for further research and understanding of its biological functions and ecological roles.
