| Description | Lactobacillus plantarum subsp. plantarum ATCC 14917 is a gram-positive, rod-shaped bacterium that thrives at mesophilic temperatures, demonstrating its adaptability as a facultative anaerobe and a chemoheterotroph. This versatile microbe is commonly isolated from various body sites, including the gastrointestinal tract, oral cavity, and vaginal microbiota, making it a key player in human health and the gut microbiome. As a gram-positive organism, L. plantarum subsp. plantarum exhibits a thick peptidoglycan layer in its cell wall, which is characteristic of its classification within the Firmicutes phylum. This structural feature not only protects the bacterium but also influences its interaction with the host immune system. Its rod shape and capability to form biofilms contribute to its resilience and ability to colonize various niches in the human body. L. plantarum subsp. plantarum's mesophilic temperature preference indicates optimal growth at moderate temperatures, typically between 30°C and 37°C. This characteristic aligns with the conditions found in the human digestive tract. As a facultative anaerobe, it can thrive in both aerobic and anaerobic conditions, making it highly adaptable to fluctuating environments within the host. Its classification as a chemoheterotroph highlights its reliance on organic compounds for energy and growth, allowing it to utilize a variety of substrates, including sugars, derived from dietary sources. This strain has garnered attention for its probiotic properties, contributing to gut health by producing lactic acid, which helps maintain an acidic environment that inhibits pathogenic bacteria. Additionally, L. plantarum subsp. plantarum is known for its capacity to ferment a wide range of carbohydrates, making it valuable in food applications such as the production of fermented dairy products and plant-based foods. Its role in promoting a balanced gut microbiota also links it to potential benefits in immune modulation and digestive health. |
