Streptococcus anginosus str. CALM001

Streptococcus anginosus strain CALM001 is a Gram-positive, nonsporulating coccus that thrives optimally at 37.0°C, making it well-suited to its habitat within the host gut. As a chemoheterotroph, this strain derives its energy from organic compounds, reflecting its adaptation to the nutrient-rich environment of the gastrointestinal tract. Furthermore, as a facultative anaerobe, S. anginosus CALM001 can respire in both the presence and absence of oxygen, allowing it to survive in the varying oxygen conditions found within the gut microbiome. The presence of S. anginosus in the gut suggests a potential role in the complex microbial community and may contribute to metabolic processes that benefit the host. Its adaptability to oxygen levels in the gut ecosystem may facilitate interactions with other microbial species, possibly influencing gut health and homeostasis. This strain exemplifies the diverse metabolic capabilities of gut-dwelling bacteria, highlighting the intricate balance of microbial life that supports host physiology.
