Ruminococcus bromii strain ATCC 27255

Ruminococcus bromii strain ATCC 27255 is a Gram-positive, cocci-shaped anaerobic bacterium predominantly found in feces and associated with the rectal mucosa of hosts. This strain is part of the diverse microbiota inhabiting the gastrointestinal tract, where it plays a significant role in the fermentation of complex carbohydrates. As an anaerobe, R. bromii thrives in oxygen-depleted environments, which is characteristic of the intestinal lumen. The presence of this bacterium in fecal samples suggests its adaptation to the gut environment, where it may contribute to the breakdown of dietary fibers, thus facilitating nutrient absorption and influencing the overall metabolic health of the host. Ruminococcus bromii is particularly notable for its ability to degrade resistant starches, which are otherwise indigestible by human enzymes. This capability not only highlights its potential role in dietary fermentation but also underscores its significance in shaping the gut microbiome's composition and functionality. Understanding the specific interactions and contributions of R. bromii within the complex ecosystem of the gut may provide insights into its role in human health and disease, particularly in relation to dietary habits and gastrointestinal function.
