Escherichia coli strain CRE1540

Escherichia coli strain CRE1540 is a Gram-negative, rod-shaped bacterium, commonly found in pairs or as single cells, that thrives at an optimal temperature of 37.0°C. This strain is classified as a facultative anaerobe, allowing it to grow in both aerobic and anaerobic environments, which is a typical characteristic of many E. coli strains. E. coli CRE1540 is host-associated, indicating a close relationship with its host organism, likely residing within the gastrointestinal tract, where it plays a role in nutrient metabolism and microbial community dynamics. The ability to adapt to varying oxygen levels enables this strain to exploit different ecological niches within the host environment, promoting its survival and proliferation. The physiological traits of E. coli CRE1540 suggest that it may participate in complex interactions within the gut microbiome, potentially influencing host health and digestion through its metabolic activities. Understanding the specific roles and behaviors of this strain within its host-associated habitat could provide insights into microbial ecology and the functional diversity of gut microbiota.
