Lactococcus lactis subsp. lactis strain 275

Lactococcus lactis subsp. lactis strain 275 is a gram-positive bacterium characterized by its cocci shape and tendency to form chains. This strain is classified as a facultative anaerobe, indicating its ability to survive in both the presence and absence of oxygen. It does not exhibit mobility, lacking flagella, and is nonsporulating, which means it does not form spores as a means of survival. This strain has an optimal growth temperature of 40°C and falls within the mesophilic temperature range, making it well-suited for environments that are neither too hot nor too cold. The bacterium is free-living, indicating its independence from a host for survival, yet it is associated with various hosts, including Homo sapiens (humans), Bos taurus (cattle), Metazoa (multicellular animals), and the plant Chrysophyllum oliviforme. Genomic analysis reveals that Lactococcus lactis subsp. lactis strain 275 contains four replicons and possesses a single membrane. These traits suggest a relatively simple cellular structure, characteristic of many lactic acid bacteria. In an ecological context, the presence of Lactococcus lactis subsp. lactis strain 275 in diverse habitats and its association with multiple hosts highlight its potential role in microbial ecosystems, particularly in fermentation processes and nutrient cycling. The strain's ability to thrive in various environments reflects its ecological versatility and importance in both natural and agricultural settings.
