Escherichia coli K-12 strain 71 GCID_CRE_0142_NODE_147

Escherichia coli K-12 strain 71, identified by the accession number SSTS00000000.1, is a Gram-negative bacterium characterized by its rod shape and the presence of flagella, which contribute to its mobility. This strain is classified as a facultative anaerobe, allowing it to thrive in both aerobic and anaerobic environments. It typically resides in host-associated habitats, indicating a close relationship with various living organisms. E. coli K-12 strain 71 is mesophilic, with an optimal growth temperature of 37°C, which is consistent with the normal human body temperature, suggesting its adaptation to warm-blooded hosts. The bacterium exhibits a unique cellular arrangement, primarily found in singles and pairs, and possesses two membranes, a trait common to Gram-negative bacteria. It has a single replicon, simplifying its genetic organization. The ecological role of E. coli K-12 strain 71 is significant, as it is classified as free-living. This indicates that, while it has associations with hosts, it can also exist independently in the environment. The ability to adapt to various oxygen conditions and its mesophilic characteristics suggest that this strain plays a critical role in nutrient cycling and microbiome dynamics, particularly in gut ecosystems where it may contribute to metabolic activities and interactions with other microbial communities.
