Aeromonas hydrophila

Aeromonas hydrophila is a Gram-negative, rod-shaped bacterium characterized by its ability to form chains, pairs, or exist as single cells. It is motile, possessing true flagella that facilitate its movement. This microbe has a complex cellular structure, featuring two cellular membranes and a genome comprised of two replicons, with relevant genomic accessions including NZ_AP019193.1 and NZ_CP038464.1. As a facultative aerobe, A. hydrophila can thrive in the presence or absence of oxygen, utilizing a heterotrophic mode of nutrition to obtain energy. The optimal growth temperature for this mesophilic organism is around 22.0°C, allowing it to flourish in a variety of environmental conditions. It is notably free-living, occupying multiple habitats, which underscores its ecological versatility. The adaptability of A. hydrophila to different environments and its motility suggest a potential role in nutrient cycling within aquatic ecosystems. This organism's ability to thrive in varied habitats positions it as a significant player in microbial communities, particularly in freshwater environments where it may influence the dynamics of both biotic and abiotic interactions.
