| Description | Lactobacillus murinus is a microorganism that thrives in environments with a temperature preference category of mesophilic, meaning it prefers temperatures between 20-45°C. This bacterium is a chemoheterotroph, utilizing organic compounds as its energy source. It produces energy through anaerobic respiration, specifically via the fermentation of sugars. L. murinus is a Gram-positive bacterium, characterized by its thick peptidoglycan layer that stains purple under Gram staining. The bacterium has a rod-shaped morphology, with dimensions typically ranging from 0.5-1.5 μm in length and 0.3-0.5 μm in width. Lactobacillus murinus has been isolated from various body sites across different species, including the gastrointestinal tract, oral cavity, and female reproductive tract. Its ability to colonize these areas is thought to be influenced by its ability to adhere to epithelial cells and its production of antimicrobial compounds. L. murinus is an obligate anaerobe, meaning it is unable to survive in the presence of oxygen. This is likely due to the fact that it lacks the necessary enzymes to protect itself from oxidative damage. Furthermore, it exhibits a preference for environments with limited oxygen availability, making it well-suited to thrive in low-oxygen environments. Despite its limited adaptability to oxygen-rich environments, L. murinus has been shown to play a crucial role in maintaining the balance of the gut microbiome. Its presence helps to regulate the activity of other microorganisms and produce key vitamins. In addition, research has also highlighted its potential applications in the development of probiotics and biotherapeutics. |
