Lactobacillus delbrueckii subsp. lactis strain FAM 21784

Lactobacillus delbrueckii subsp. lactis strain FAM 21784 is a Gram-positive, rod-shaped bacterium that thrives in multiple habitats, demonstrating its versatility and adaptability. This strain is classified as a facultative anaerobe, meaning it can grow in both the presence and absence of oxygen. It typically forms chains and exhibits no mobility, indicating a static lifestyle within its environments. The optimal growth temperature for strain FAM 21784 is 42°C, placing it within the mesophilic temperature range, which generally encompasses organisms that prefer moderate temperature environments. This adaptation may allow it to thrive in specific niches where temperature fluctuations occur, such as in fermented foods or certain human-associated environments. Lactobacillus delbrueckii subsp. lactis strain FAM 21784 has a single replicon and a single membrane, which is characteristic of many lactic acid bacteria. It is free-living and has been identified as a host to Homo sapiens, suggesting its potential role in human-associated microbiomes. The presence of flagella has been noted, although the specific functional implications of this feature in relation to its ecological interactions remain to be fully characterized. Overall, the traits of Lactobacillus delbrueckii subsp. lactis strain FAM 21784 reflect its adaptability and potential significance in various ecological contexts, particularly in relation to human health and food fermentation processes.
