Lactococcus lactis subsp. lactis CNCM I-1631

Lactococcus lactis subsp. lactis CNCM I-1631 is a Gram-positive, nonsporulating cocci that exhibits facultative anaerobic metabolism and thrives optimally at a temperature of 40.0°C. This strain is part of a diverse group of lactic acid bacteria commonly found in various habitats, including dairy environments, where it plays a crucial role in fermentation processes. As a member of the Lactococcus genus, L. lactis subsp. lactis CNCM I-1631 is notable for its ability to ferment lactose, producing lactic acid, which contributes to the preservation and flavor development in fermented dairy products. The strain's adaptability to both aerobic and anaerobic conditions allows it to flourish in environments with fluctuating oxygen levels, further enhancing its utility in food biotechnology. The ecological versatility of L. lactis subsp. lactis CNCM I-1631 underscores its significance in both natural and industrial fermentation processes. Its presence in multiple habitats suggests a robust capacity for survival and adaptation, potentially enabling it to interact with various microbial communities. This characteristic may contribute to its functional applications in food science, particularly in the development of starter cultures for cheese production and other fermented products, where specific metabolic traits can influence the overall quality and characteristics of the final product.
