Escherichia coli M114

Escherichia coli M114 is a Gram-negative, rod-shaped bacterium that typically exists in pairs or as single cells. This strain is categorized as a facultative anaerobe, indicating its ability to survive in both aerobic and anaerobic environments. It thrives optimally at a temperature of 37.0°C, which aligns with the body temperature of many warm-blooded hosts, suggesting its adaptation to a host-associated habitat. E. coli M114's Gram-negative cell wall structure, characterized by a thin peptidoglycan layer and an outer membrane containing lipopolysaccharides, contributes to its resilience in diverse environments and may influence its interactions with the host's immune system. The arrangement of cells in pairs or singles may facilitate rapid colonization and adaptability in various niches within a host organism. The facultative anaerobic nature of E. coli M114 allows it to exploit different metabolic pathways depending on the availability of oxygen, which can provide a competitive advantage in fluctuating environments within the gastrointestinal tract and other host-associated habitats. This metabolic versatility highlights the ecological importance of E. coli M114 in microbial communities, where it may play roles in nutrient cycling and the maintenance of gut homeostasis. Understanding the traits of this strain can offer insights into the broader ecological dynamics of host-associated microbial populations.
