Escherichia coli KK-NP011

Escherichia coli KK-NP011 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. The optimal growth temperature for E. coli KK-NP011 is 37.0 °C, aligning with the typical thermal preference of many enteric bacteria and suggesting its adaptation to host-associated habitats, such as the gastrointestinal tract of warm-blooded animals. The Gram-negative nature of E. coli KK-NP011 is significant, as it features a double membrane structure that includes an outer membrane containing lipopolysaccharides, which can play a role in its interactions with host organisms. The presence of this structural feature may influence its survival strategies and metabolic flexibility in fluctuating environmental conditions. Given its facultative anaerobic capability, E. coli KK-NP011 can adapt to varying oxygen levels, which is particularly advantageous in host-associated environments where oxygen concentration may differ across niches. This adaptability may also provide insights into its potential roles in microbial communities within the host, including nutrient cycling and maintaining gut homeostasis. Understanding the traits of E. coli KK-NP011 can contribute to broader studies on microbial interactions in host-associated ecosystems.
