Escherichia coli str. 256

Escherichia coli str. 256 is a Gram-negative, rod-shaped bacterium that typically occurs in pairs or as single cells. This strain thrives optimally at 37.0°C, which is indicative of its adaptation to warm-blooded hosts, aligning with its habitat as a host-associated microbe. E. coli str. 256 exhibits facultative anaerobic respiration, allowing it to survive in both aerobic and anaerobic environments, a trait that enhances its versatility in various ecological niches within the host. This adaptability may facilitate its role in the gut microbiome, where it can contribute to digestive processes while competing with other microorganisms. E. coli is known for its ability to metabolize a wide range of substrates, which may reflect its evolutionary success in diverse host-associated environments. Understanding the traits of E. coli str. 256 not only contributes to our knowledge of this specific strain but also highlights the ecological complexities of intestinal microbiota, where such bacteria play crucial roles in maintaining host health and influencing metabolic pathways.
