Cutibacterium granulosum DSM 20700

Cutibacterium granulosum DSM 20700 is a Gram-positive, mesophilic bacterium that inhabits the host epidermis. This species is classified as a chemoheterotroph, deriving its energy from organic compounds. C. granulosum is characterized by its rod shape and is non-motile, lacking the ability to move independently due to the absence of flagella. However, it is noted that this bacterium does have flagella present, which may play a role in its ecological interactions. C. granulosum is strictly anaerobic, meaning it thrives in environments devoid of oxygen. This characteristic indicates it may inhabit niches on the skin that are less exposed to oxygen, possibly contributing to the complex microbial communities found on human skin. The genomic structure of C. granulosum is notable, with two replicons identified in its genome. This trait may have implications for its adaptability and genetic diversity within its ecological niche. Overall, the presence of Cutibacterium granulosum in the host epidermis underscores the importance of anaerobic bacteria in human skin microbiota, potentially influencing skin health and microbial balance. The insights into its metabolic capabilities and habitat reinforce the role of this bacterium in maintaining the skin's ecological equilibrium.
