Lactobacillus farciminis strain CNCM-I-3699-S.

Lactobacillus farciminis strain CNCM-I-3699-S is a nonsporulating, rod-shaped bacterium classified as a chemoheterotroph, indicating it derives energy from organic compounds. This strain is a facultative anaerobe, meaning it can grow in both the presence and absence of oxygen, which allows it to thrive in diverse environments. It is mesophilic, with an optimal growth temperature of 37°C, making it well-suited for environments that reflect mammalian body temperatures. Lactobacillus farciminis strain CNCM-I-3699-S has a single replicon and lacks mobility, as it does not possess flagella. This characteristic suggests a stable lifestyle, likely adapted to specific habitats where it can exploit available nutrients without the need for motility. The ecological significance of Lactobacillus farciminis may lie in its role in various microbial communities, particularly in fermentation processes or as part of the gut microbiota in mammals. Its ability to function both in aerobic and anaerobic conditions enables it to participate in different metabolic pathways, contributing to nutrient cycling and potentially influencing host health. The strain’s adaptability to multiple habitats further emphasizes its ecological versatility and importance in microbiological and biotechnological applications.
