Escherichia coli str. PF9285

Escherichia coli strain PF9285 is a Gram-negative, rod-shaped bacterium that exhibits a cell arrangement predominantly in pairs and singles. This strain thrives optimally at a temperature of 37.0°C, which is characteristic of many mesophilic organisms, particularly those associated with warm-blooded hosts. As a facultative anaerobe, E. coli PF9285 possesses the metabolic versatility to utilize both aerobic and anaerobic respiration, allowing it to adapt to varying oxygen conditions within its host-associated habitat. The ecological niche of E. coli PF9285 underscores its potential role in host microbiomes, where it may contribute to essential processes such as nutrient metabolism and gut homeostasis. The ability of this strain to grow in both oxygen-rich and oxygen-depleted environments suggests that it can occupy diverse microenvironments within the host, potentially influencing microbial community dynamics. This adaptability not only highlights the metabolic resilience of E. coli PF9285 but also emphasizes its significance in the complex interactions that occur within host-associated microbial ecosystems. Further research may elucidate the specific functions and interactions of this strain within its ecological context.
