| Description | Collinsella tanakaei is a Gram-positive, rod-shaped bacterium that thrives in a mesophilic temperature range, categorizing it as a heterotroph and an obligate anaerobe. This microbe is primarily found in the human gut, particularly in the intestinal microbiota, where it plays a significant role in nutrient metabolism and maintaining gut health. Its presence has been linked to various physiological processes, including the fermentation of dietary fibers and the production of short-chain fatty acids, which are crucial for colon health. As a Gram-positive organism, Collinsella tanakaei retains the crystal violet stain used in Gram staining procedures, indicating a thick peptidoglycan layer in its cell wall. This structural characteristic provides resilience in anaerobic environments, where it can thrive without the presence of oxygen, using alternative electron acceptors during metabolism. Being a rod-shaped bacterium, it exhibits a unique morphology that facilitates its motility and colonization within the gut environment. Collinsella tanakaei is an important member of the human microbiome due to its role in digestion and its influence on the immune system. Recent studies have suggested associations between Collinsella tanakaei levels and various health conditions, including obesity and metabolic disorders. Its ability to adapt to the anaerobic conditions of the gut and metabolize complex carbohydrates demonstrates its ecological significance in maintaining a balanced microbiota. Further research into Collinsella tanakaei could shed light on its therapeutic potential in the management of gastrointestinal health and overall metabolic function. |
