Lactococcus cremoris subsp. cremoris KW2

Lactococcus cremoris subsp. cremoris KW2 is a Gram-positive, non-motile coccus that thrives in various habitats. This bacterium is classified as a facultative anaerobe, allowing it to survive in both aerobic and anaerobic environments. It has an optimal growth temperature of 40°C and falls within the mesophilic temperature range, indicating its preference for moderate temperatures. Lactococcus cremoris subsp. cremoris KW2 is characterized by possessing a single replicon and one membrane, which is typical for many lactic acid bacteria. The organism does not undergo sporulation, indicating that it does not form spores as a means of survival under adverse conditions. Additionally, it is free-living, highlighting its independence in the ecosystem. The presence of flagella has been noted, which is unusual for many non-motile bacteria; however, in this case, it may not confer any significant mobility, as the organism is still classified as non-motile. The accession number for this strain is NC_022369.1, providing a reference for genomic studies and further research. Biologically, the ability to thrive in diverse environments and its mesophilic nature suggest that Lactococcus cremoris subsp. cremoris KW2 plays a significant role in various fermentation processes, particularly in dairy products. This versatility in habitat and optimal growth conditions may contribute to its importance in microbial ecology and food production.
