Pseudobutyrivibrio ruminis strain JK626

Pseudobutyrivibrio ruminis strain JK626 is a Gram-positive anaerobic bacterium that resides in the intestinal microflora of animals, specifically within the digestive systems of Bos (cattle) and Ovis aries (sheep). This strain is classified as a chemoheterotroph, deriving its energy from organic compounds, which is typical for bacteria inhabiting the gut environment where diverse nutrients are available. This organism is motile, possessing flagella, which may facilitate its movement within the viscous intestinal environment. Pseudobutyrivibrio ruminis strain JK626 thrives at an optimal temperature of 39°C and falls within the mesophilic temperature range, indicating its adaptation to the warm conditions often found in animal intestines. Notably, this strain does not form spores, which could suggest a reliance on stable environments provided by its host. With a singular replicon, the genomic simplicity may reflect a streamlined adaptation to its specific ecological niche. The presence of Pseudobutyrivibrio ruminis in the intestines of ruminants plays a significant role in the fermentation processes associated with the digestion of complex carbohydrates, contributing to the overall health and metabolic efficiency of its hosts. Understanding the characteristics of this strain can provide insights into its contributions to the gut microbiome, particularly in relation to energy extraction and nutrient cycling within ruminant digestive systems.
