Roseburia intestinalis strain AM22-21LB

Roseburia intestinalis strain AM22-21LB is a Gram-positive, non-motile, rod-shaped bacterium that resides in the intestinal microflora of Homo sapiens. This strain is classified as a chemoheterotroph, relying on organic compounds as its energy source. It is strictly anaerobic, thriving in environments devoid of oxygen, which is consistent with its habitat in the gut where such conditions are prevalent. The optimal temperature for the growth of R. intestinalis strain AM22-21LB is 37°C, placing it within the mesophilic temperature range. This preference aligns well with the physiological temperature of the human body, further supporting its role in the intestinal microbiome. Notably, this strain has one replicon, indicating a relatively simple genetic organization. R. intestinalis is recognized for its potential contributions to gut health, including the fermentation of dietary fibers and the production of short-chain fatty acids, which are beneficial for colonic health and metabolic processes. The presence of this bacterium in the human gut may play a role in maintaining a balanced microbiota, which is essential for optimal digestive function and overall health. In summary, Roseburia intestinalis strain AM22-21LB exemplifies the characteristics of a specialized gut bacterium, adapted to its anaerobic environment and contributing to the complex ecosystem of the human intestinal microflora.
