Parasutterella excrementihominis YIT 11859

Parasutterella excrementihominis YIT 11859 is a gram-negative, rod-shaped bacterium that thrives in anaerobic environments, classified as an obligate anaerobe. It prefers mesophilic temperatures, typically growing optimally between 30°C and 37°C. As a chemoheterotroph, this microbe derives its energy from organic compounds, specifically within the complex environment of the human gut. This species is predominantly found in the intestines of healthy humans, where it plays a significant role in the gut microbiome. Its presence is linked with the fermentation of dietary fibers and the metabolism of complex carbohydrates, contributing to the overall health of the gut ecosystem. The ability to utilize a wide range of organic substrates allows *Parasutterella excrementihominis* to adapt to different dietary regimens, which is crucial for maintaining gut homeostasis. As a gram-negative bacterium, *Parasutterella excrementihominis* possesses a thin peptidoglycan layer and an outer membrane rich in lipopolysaccharides. This structural characteristic not only plays a role in its pathogenicity and immune evasion but may also influence its interactions with the host's immune system. Research suggests that the microbiota composition, including species like *Parasutterella excrementihominis*, can impact metabolic functions and might even be linked to various health conditions, such as obesity and inflammatory bowel disease. Emerging studies indicate that, due to its metabolic capabilities, *Parasutterella excrementihominis* could potentially be harnessed in therapeutic applications aimed at restoring dysbiosis in the human gut microbiota. Its involvement in complex biochemical pathways further highlights the intricate relationships between gut microbes and human health.
