Enterococcus faecalis strain AR99-84

Enterococcus faecalis strain AR99-84 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 its ability to utilize organic compounds as energy sources. Enterococcus faecalis is known to inhabit a variety of environments, which suggests its ecological versatility. The coccal morphology of E. faecalis contributes to its resilience in diverse habitats, including the gastrointestinal tracts of humans and other animals, as well as in soil and water. The facultative anaerobic nature of this strain allows it to survive in both aerobic and anaerobic conditions, enhancing its adaptability to fluctuating environmental oxygen levels. Furthermore, the ability to thrive at an optimal temperature of 37.0°C aligns with its association with warm-blooded hosts, where it frequently plays a role in the complex microbiota. This adaptability and metabolic flexibility may facilitate its persistence in various niches, potentially influencing microbial community dynamics and nutrient cycling in those ecosystems. Understanding the traits of Enterococcus faecalis strain AR99-84 may provide insight into its ecological roles and interactions within microbial communities, particularly in environments where organic matter is abundant.
