Escherichia coli str. NUBRI-E

Escherichia coli strain NUBRI-E is a Gram-negative, rod-shaped bacterium that typically exists in pairs or as single cells. This strain is classified as a facultative anaerobe, indicating its ability to thrive in both aerobic and anaerobic environments. E. coli NUBRI-E has an optimal growth temperature of 37.0 °C, which aligns with the physiological temperature of many mammalian hosts, suggesting a potential adaptation for survival within host-associated habitats. The ability of E. coli NUBRI-E to inhabit host-associated environments reflects its versatile metabolic capabilities, allowing it to utilize various substrates for energy production. This adaptability may enhance its survival in diverse ecological niches, particularly within the gastrointestinal tracts of warm-blooded animals. The facultative anaerobic nature of this strain further implies that it can efficiently switch between aerobic respiration and fermentation, providing a competitive advantage in fluctuating oxygen conditions commonly found in host environments. Understanding the traits of E. coli NUBRI-E can offer insights into its role in microbial communities associated with hosts, where it may contribute to essential processes such as nutrient cycling and maintaining gut homeostasis. The strain's metabolic flexibility and optimal growth temperature suggest a sophisticated adaptation to host-associated life, highlighting the intricate relationships between microbial inhabitants and their hosts.
