Enterococcus faecalis strain 13-2-19

Enterococcus faecalis strain 13-2-19 is a Gram-positive, nonsporulating coccus that exhibits facultative anaerobic metabolism, indicating its ability to grow in both aerobic and anaerobic environments. This strain thrives optimally at a temperature of 37.0°C, which is consistent with the conditions found in the mammalian gut, where Enterococcus species are commonly encountered. As a chemoorganotroph, E. faecalis strain 13-2-19 utilizes organic compounds as its energy source, which further supports its role in diverse habitats, including those associated with human and animal microbiomes. The ability of E. faecalis to occupy multiple habitats suggests a versatile ecological niche, potentially contributing to its persistence and adaptability in various environments. This strain's metabolic capabilities may facilitate its survival and proliferation in complex microbial communities, where it can engage in interactions with other microorganisms. Furthermore, the facultative anaerobic nature of this strain highlights its ecological flexibility, allowing it to thrive in fluctuating oxygen conditions, which are characteristic of many environments, including the gastrointestinal tract. Overall, the traits of Enterococcus faecalis strain 13-2-19 underscore its potential role in microbial ecology, particularly within environments rich in organic substrates where it may contribute to nutrient cycling and microbiota stability.
