Escherichia coli ATCC BAA-2209

Escherichia coli ATCC BAA-2209 is a Gram-negative, rod-shaped bacterium that typically exists in single or paired arrangements. This strain is a facultative anaerobe, meaning it can grow in both aerobic and anaerobic environments, which is characteristic of many E. coli strains. It thrives optimally at a temperature of 37.0°C, aligning with the average body temperature of warm-blooded hosts, suggesting a close association with host organisms. E. coli ATCC BAA-2209 is categorized as host-associated, indicating its prevalence in the gastrointestinal tracts of various animals, including humans. This habitat is critical for its role in digestion and nutrient absorption, as well as its involvement in the complex microbial ecosystems within the gut. The ability to survive in different oxygen conditions enables this strain to adapt to varying environments within the host, where oxygen levels can fluctuate. Given its optimal growth temperature and facultative anaerobic nature, E. coli ATCC BAA-2209 exemplifies the adaptability of gut microbiota. This adaptability allows it to play a significant role in maintaining intestinal health and homeostasis, as well as in the fermentation of undigested carbohydrates, contributing to the overall metabolic activities within the host's digestive system. Understanding the traits of this strain can provide insights into its ecological niche and potential applications in biotechnology and microbiome research.
