Aliivibrio fischeri MJ11

Aliivibrio fischeri MJ11 is a Gram-negative, rod-shaped bacterium that exists as single cells and demonstrates facultative anaerobic metabolism. This microorganism is a heterotroph, utilizing organic compounds as its energy source, which allows it to thrive in a variety of habitats. The optimal growth temperature for A. fischeri MJ11 is 20.0°C, suggesting a preference for cooler environments, which may reflect its adaptation to marine or brackish ecosystems. The ability of A. fischeri MJ11 to function as a facultative anaerobe indicates its metabolic versatility, allowing it to survive in both oxygen-rich and oxygen-poor conditions. This trait is particularly advantageous in fluctuating environmental conditions, enhancing its ecological resilience. In summary, the unique combination of its Gram-negative cell structure, rod shape, and heterotrophic lifestyle positions Aliivibrio fischeri MJ11 as a potentially important player in nutrient cycling within its habitats, as it may contribute to the breakdown of organic matter and the overall health of microbial communities.
