| Description | Lacticaseibacillus paracasei subsp. paracasei is a Gram-positive, nonsporulating bacterium that exhibits a bacilli shape and typically forms chains. This mesophilic microorganism thrives optimally at 30°C and operates as a facultative anaerobe, allowing it to adapt to varying oxygen levels in its environment. L. paracasei subsp. paracasei is a chemoheterotroph, primarily utilizing fermentative metabolism to derive energy from organic substrates, with a notable ability to ferment lactose and other sugars. This microbe is commonly found in diverse habitats, including fermented dairy products such as yogurt and cheese, where it plays a crucial role in the fermentation process. It can also be isolated from the gastrointestinal tracts of animals and humans, contributing positively to gut health by enhancing the microbial balance. Its probiotic properties have garnered attention for potential health benefits, including modulation of the immune system, improvement of lactose digestion, and production of bioactive compounds. Interestingly, Lacticaseibacillus paracasei subsp. paracasei demonstrates resilience under various stress conditions, including acid and bile salts, making it a candidate for probiotic formulations aimed at enhancing gut microbiota diversity. This adaptability not only benefits its survival in challenging environments but also highlights its potential role in promoting human health and supporting the microbiome during antibiotic treatments or digestive disturbances. |
