Escherichia coli strain FWSEC0439

Escherichia coli strain FWSEC0439 is a Gram-negative, rod-shaped bacterium that typically exists in pairs or as single cells. This strain is adapted to a host-associated environment, indicating its presence in association with living organisms, which is characteristic of many E. coli strains. E. coli FWSEC0439 demonstrates facultative anaerobic metabolism, allowing it to thrive in both aerobic and anaerobic conditions, which is advantageous for its survival in various host environments. The optimal growth temperature for E. coli FWSEC0439 is 37.0°C, which aligns with the average body temperature of warm-blooded hosts, further supporting its adaptation to a host-associated niche. This temperature preference suggests that the strain may be well-suited to inhabit the intestinal tract of mammals, where it can play a role in digestion and nutrient absorption. Understanding the traits of Escherichia coli strain FWSEC0439 contributes to our knowledge of its potential functions in microbial communities within host organisms. Its facultative anaerobic nature and optimal growth conditions highlight the adaptability of this strain in host-associated environments, which may influence microbial dynamics and interactions within the gut microbiome.
