Escherichia coli str. SLK172

Escherichia coli strain SLK172 is a Gram-negative, rod-shaped bacterium that commonly exists in a host-associated habitat. This strain exhibits a cellular arrangement primarily in pairs and singles, reflecting its typical morphology within diverse environments. E. coli SLK172 thrives optimally at a temperature of 37.0°C, which aligns with the physiological conditions found in the intestines of warm-blooded hosts. As a facultative anaerobe, E. coli SLK172 possesses the metabolic flexibility to grow in both the presence and absence of oxygen, enabling it to adapt to varying oxygen levels within its host environment. This adaptability is crucial for survival in the dynamic conditions of the gastrointestinal tract, where oxygen availability can fluctuate significantly due to microbial activity and host physiology. The association of E. coli SLK172 with host organisms suggests potential roles in nutrient metabolism and microbial community dynamics within the gut ecosystem. Understanding the specific interactions of this strain with its host could provide insights into its contributions to health and disease, as well as its potential influence on the overall gut microbiome. Such knowledge may further illuminate the ecological significance of E. coli strains in maintaining gut homeostasis and their responses to environmental changes.
