Roseburia inulinivorans DSM 16841

Roseburia inulinivorans DSM 16841 is a Gram-positive, rod-shaped bacterium classified as an obligate anaerobe. This organism thrives optimally at mesophilic temperatures, typically ranging between 30°C to 37°C, making it well-suited for the human gut environment. As a heterotroph, Roseburia inulinivorans relies on organic compounds for its energy and growth, specifically fermenting dietary fibers such as inulin, a polysaccharide commonly found in many plants. This bacterium is primarily isolated from the human gastrointestinal tract, where it plays a pivotal role in the fermentation of dietary fibers into short-chain fatty acids (SCFAs), particularly butyrate. Butyrate is significant for colonic health, serving as an energy source for colonocytes and contributing to the maintenance of gut integrity and function. Roseburia inulinivorans can also be found in the fecal microbiota of various populations, highlighting its importance in human health and the gut microbiome's diversity. With its ability to process inulin, Roseburia inulinivorans is often associated with the consumption of prebiotic-rich foods, such as artichokes, garlic, and onions. Its proliferation in the gut is linked to various health benefits, including potential anti-inflammatory properties and modulation of immune responses. Moreover, this microbe's presence is inversely correlated with conditions such as obesity and type 2 diabetes, indicating its role in metabolic health. Overall, Roseburia inulinivorans serves as a crucial player in the gut ecosystem, illustrating the intricate relationship between diet, microbial diversity, and human health.
