| Description | Lactobacillus animalis KCTC 3501 = DSM 20602 is a Gram-positive, rod-shaped bacterium that thrives in mesophilic temperatures, categorizing it as a heterotroph and functioning as a facultative anaerobe. This microbe is primarily found in various body sites of animals, most notably the gastrointestinal tract, where it plays a crucial role in digestion and gut health, as well as in fermented dairy products. Being Gram-positive, Lactobacillus animalis possesses a thick peptidoglycan layer, which contributes to its structural integrity and ability to withstand environmental pressures. The rod shape allows for efficient nutrient absorption and colonization of host environments. As a mesophilic organism, it prefers moderate temperatures, typically ranging from 30°C to 37°C, making it well-suited for the warm environments found in the intestines of mammals. Lactobacillus animalis is a heterotroph, meaning it relies on organic compounds for energy and carbon, which it derives from the fermentation of sugars present in its environment. This metabolic flexibility enables it to adapt to varying conditions within the gut. As a facultative anaerobe, it can survive in both oxygen-rich and oxygen-poor conditions, utilizing aerobic respiration when oxygen is available and switching to fermentation processes in anaerobic environments. This bacterium also has significant applications in the food industry, especially in the production of yogurt and probiotic supplements. It is recognized for its health benefits, including improving lactose digestion, enhancing immune function, and potentially combating pathogenic bacteria in the gut. Lactobacillus animalis has garnered attention in research for its role in modulating gut microbiota and promoting overall health, making it a valued candidate in the study of probiotics and gut health management. |
