Streptococcus gordonii strain KCOM 1506 (= ChDC B679)

Streptococcus gordonii strain KCOM 1506 (also known as ChDC B679) is a Gram-positive, coccoid bacterium that typically arranges itself in chains and pairs. This strain is a facultative anaerobe, indicating its ability to grow in both aerobic and anaerobic environments. Optimal growth occurs at a temperature of 37.0°C, which aligns with its habitat in host-associated environments. As a member of the Streptococcus genus, S. gordonii is often found as part of the normal flora in the human oral cavity, contributing to the complex microbial community present in this niche. Its status as a facultative anaerobe suggests that it plays a versatile role in the metabolic processes occurring within the host, particularly in the dental biofilm where it may interact with other microbial species. The ability of S. gordonii to thrive at body temperature makes it well-suited for life in mammals, where it can engage in various symbiotic relationships. This strain's specific ecological niche may reflect its evolutionary adaptations, enabling it to participate in the maintenance of oral health and potentially influencing host-microbe interactions. Additionally, its arrangement in chains and pairs may facilitate communication and cooperation among cells, which could play a critical role in its survival and function within the host-associated habitat.
