| Description | Bacteroides barnesiae DSM 18169 = JCM 13652 is a Gram-negative, anaerobic bacterium belonging to the Bacteroides genus. It is typically found in the gut microbiome of various hosts, where it plays a crucial role in digestion and nutrient absorption. This bacterium is nonsporulating, existing primarily as individual cells or in pairs, which facilitates its adaptation within the complex gut environment. Bacteroides barnesiae is a chemoorganotroph, relying on organic compounds for energy, and it primarily utilizes fermentation as its metabolic pathway. The optimal growth temperature for this organism is around 37°C, aligning with the physiological temperature of its mammalian hosts. This adaptation enables it to thrive in the gastrointestinal tract, where it contributes to the degradation of complex carbohydrates, thus aiding in nutrient breakdown and absorption. The presence of Bacteroides barnesiae in the gut microbiome is significant for maintaining a balanced microbial ecosystem. It aids in fermenting dietary fibers, producing short-chain fatty acids (SCFAs) that are beneficial for host health, including anti-inflammatory effects and enhancing gut barrier function. The interactions between Bacteroides barnesiae and other gut microorganisms may influence the host's immune response and overall well-being. This highlights the importance of understanding gut microbiota composition and function, as disturbances in these populations can lead to health issues such as obesity, diabetes, and inflammatory bowel diseases. |
