Roseburia intestinalis strain AF31-21AC

Roseburia intestinalis strain AF31-21AC is a gram-positive, non-motile, rod-shaped bacterium primarily found in the intestinal microflora of animals, specifically Homo sapiens. As a chemoheterotroph, it utilizes organic compounds as its energy source. This strain is an anaerobe, thriving in environments devoid of oxygen, which is characteristic of the gastrointestinal tract. The optimal growth temperature for R. intestinalis strain AF31-21AC is 37°C, placing it within the mesophilic temperature range. It has a simple genomic structure, possessing only one replicon. This bacterium does not undergo sporulation, which is consistent with its adaptation to a stable intestinal environment. The presence of flagella suggests potential motility, although the strain is classified as non-motile. This contradiction may indicate a structural trait without functional significance in its natural habitat. The accession number for this strain is QRQN00000000.1, which allows for further reference and study. The ecological role of Roseburia intestinalis strain AF31-21AC in the human gut is likely significant, contributing to the maintenance of intestinal health and homeostasis. Its presence in the gut microflora may play a role in digestion and nutrient absorption, underscoring the importance of anaerobic bacteria in the complex ecosystem of the human microbiome. Understanding such strains can provide insights into gut health and the implications of microbial diversity in relation to human physiology.
