Pseudobutyrivibrio ruminis DSM 9787

Pseudobutyrivibrio ruminis DSM 9787 is a Gram-positive, anaerobic bacterium that is part of the intestinal microflora in animals. As a chemoheterotroph, it derives energy from organic compounds, which aligns with its ecological role in the gut environment where it contributes to the fermentation of dietary fibers and other nutrients. This species has a mesophilic temperature range, with an optimal growth temperature of 39°C, indicating that it thrives in warm environments typical of the animal intestinal tract. Pseudobutyrivibrio ruminis possesses mobility, facilitated by the presence of flagella, which likely aids in its colonization and interaction within the complex microbial communities of the gut. Notably, Pseudobutyrivibrio ruminis is nonsporulating and possesses a single replicon, suggesting a relatively simple genetic organization. The lack of sporulation indicates that this bacterium relies on its anaerobic environment for survival and reproduction rather than developing spores as a means to withstand adverse conditions. In terms of ecological insight, the presence of Pseudobutyrivibrio ruminis within the gut microbiota underscores its potential role in maintaining gut health and contributing to the fermentation processes that produce beneficial short-chain fatty acids (SCFAs). These SCFAs are important for host energy metabolism and overall gut homeostasis, highlighting the significance of this bacterium in the symbiotic relationship between animals and their gut microbiota.
