Enterococcus faecalis str. HA-1

Enterococcus faecalis str. HA-1 is a Gram-positive, nonsporulating coccus that exhibits facultative anaerobic metabolism and thrives optimally at 37.0°C. This strain is classified as a chemoorganotroph, indicating that it derives energy by oxidizing organic compounds, which allows it to inhabit diverse environments. Enterococcus faecalis, as a species, is known for its versatile metabolic capabilities, enabling it to survive in various ecological niches, including the gastrointestinal tracts of humans and animals, as well as in hospital settings. The coccal morphology of E. faecalis str. HA-1 contributes to its resilience in different habitats, where it can adapt to varying levels of oxygen availability. Its facultative anaerobic nature allows it to switch between aerobic respiration and fermentation depending on the oxygen conditions, further enhancing its survival and proliferation in fluctuating environments. In summary, Enterococcus faecalis str. HA-1 exemplifies a microbe well-adapted to diverse habitats through its metabolic flexibility and robust morphological characteristics. This adaptability may play a significant role in its ecological interactions and survival strategies, suggesting a nuanced relationship with its environment that warrants further investigation.
