Escherichia coli strain FWSEC0438

Escherichia coli strain FWSEC0438 is a Gram-negative, rod-shaped bacterium that typically exists in pairs or as single cells. This strain thrives optimally at a temperature of 37.0°C, which aligns with its habitat as a host-associated microbe, commonly found within the gastrointestinal tract of warm-blooded animals, including humans. As a facultative anaerobe, FWSEC0438 possesses the metabolic versatility to grow in both aerobic and anaerobic environments, allowing it to adapt to varying conditions within its host's digestive system. The ability of E. coli strain FWSEC0438 to survive and proliferate in the host's gut highlights its potential role in the complex microbial community, contributing to nutrient metabolism and gut health. Additionally, its facultative anaerobic nature suggests that it can effectively compete for resources within fluctuating oxygen levels, further emphasizing its ecological significance. Understanding the specific traits of FWSEC0438 can provide insights into its interactions within the microbiome and its potential contributions to host physiology.
