Cutibacterium acnes JCM 18909

Cutibacterium acnes JCM 18909 is a Gram-positive, anaerobic bacterium characterized by its rod shape and non-motility. It is associated with host environments, indicating its presence in biological systems, particularly on human skin. This species thrives optimally at a temperature of 37°C, which aligns with the typical human body temperature, suggesting a specialized adaptation to its niche. As a mesophilic organism, C. acnes operates effectively within a temperature range conducive to growth and metabolic activity that aligns with that of warm-blooded hosts. It possesses a single membrane and a single replicon, indicating a relatively simple cellular organization, which is typical for many anaerobic bacteria. C. acnes is classified as non-sporulating, suggesting that it does not form spores as a means of survival under adverse conditions. Instead, it maintains a free-living biotic relationship, indicating its independence from other organisms for survival, despite its close association with human skin. The presence of flagella in C. acnes indicates potential for motility, although it is noted to be non-motile in practice. This could imply adaptation strategies that allow it to thrive in stable environments without the need for movement. Overall, Cutibacterium acnes JCM 18909 plays a significant role in the human microbiome, contributing to skin health and potentially influencing ecological dynamics in microbial communities on the skin’s surface. Its ability to thrive in anaerobic conditions highlights its evolutionary adaptation to host-associated habitats.
