Escherichia coli strain KCJK3945

Escherichia coli strain KCJK3945 is a Gram-negative, rod-shaped bacterium characterized by its occurrence in pairs and singles. This strain thrives optimally at a temperature of 37.0°C, aligning with the typical human body temperature, which suggests its potential association with warm-blooded hosts. As a facultative anaerobe, E. coli strain KCJK3945 can survive in both aerobic and anaerobic environments, allowing it to adapt to varying conditions within its host-associated habitat. The Gram-negative nature of this strain indicates the presence of an outer membrane, which plays a critical role in its interactions with the host's immune system and may influence its physiological responses. The rod shape of E. coli facilitates motility and colonization, which are essential for its survival and function within host environments. Given its habitat, E. coli strain KCJK3945 may contribute to the complex microbiota of the gastrointestinal tract, where it can play roles in nutrient absorption and synthesis of essential vitamins. The ability to thrive in both oxygen-rich and oxygen-poor areas of the gut suggests a versatile metabolic capacity, which may help maintain its presence and function in diverse microenvironments. The ecological significance of E. coli strain KCJK3945 may extend to its interactions with other microbial species, contributing to the overall homeostasis of the gut microbiome.
