Aeromonas hydrophila subsp. hydrophila

Aeromonas hydrophila subsp. hydrophila is a Gram-negative, rod-shaped bacterium that typically exists in various arrangements, including chains, pairs, and singles. This organism demonstrates a facultative aerobic metabolism, allowing it to thrive in both oxygen-rich and oxygen-poor environments. As a heterotroph, A. hydrophila subsp. hydrophila relies on organic compounds for energy, which is consistent with its adaptability to diverse habitats, including freshwater and brackish environments. The optimal growth temperature for A. hydrophila subsp. hydrophila is approximately 22.0 °C, indicating a preference for temperate conditions. This temperature preference may reflect its ecological adaptability, enabling it to inhabit a range of aquatic environments where temperatures fluctuate seasonally. The versatile nature of A. hydrophila subsp. hydrophila not only underscores its ecological resilience but also suggests its potential role in nutrient cycling within its habitats. Given its diverse habitat and growth characteristics, A. hydrophila subsp. hydrophila may contribute significantly to the microbiota of aquatic ecosystems, where it could play roles in organic matter degradation and the maintenance of ecological balance. Understanding its physiological traits can provide insights into its ecological functions and interactions within microbial communities.
