Lactococcus lactis subsp. lactis strain 14B4

Lactococcus lactis subsp. lactis strain 14B4 is a Gram-positive, non-motile bacterium that belongs to the family of lactic acid bacteria. This strain exhibits a cocci shape and typically arranges itself in chains. It is classified as a facultative anaerobe, indicating its ability to thrive in both aerobic and anaerobic environments. The optimal growth temperature for strain 14B4 is 40°C, placing it in the mesophilic temperature range. This strain is characterized by having two replicons and a single membrane, which is a common feature among lactic acid bacteria. Lactococcus lactis subsp. lactis strain 14B4 does not form spores, which is typical for many species within this genus. Lactococcus lactis subsp. lactis strain 14B4 is known to have a free-living biotic relationship, and it has been isolated from diverse habitats, including associations with Homo sapiens (humans), Bos taurus (cattle), various Metazoa (multicellular animals), and Chrysophyllum oliviforme (a type of flowering plant). The ecological role of Lactococcus lactis subsp. lactis strain 14B4 is significant in various fermentation processes, particularly in dairy products, where it contributes to flavor and texture. Its presence in multiple hosts suggests a versatile adaptability and potential for symbiotic relationships within different ecosystems, highlighting its importance in microbial interactions and food production.
