Lactococcus Lactis Subsp

Lactococcus lactis subsp. is a type of bacteria commonly used in food production. It is a lactic acid bacterium, meaning it produces lactic acid as part of its metabolic process. These bacteria are often grown in milk or other nutrient-rich media for use as starter cultures.

This bacterium is widely used as a starter culture in the fermentation of dairy products like yogurt, cheese, and kefir. It contributes to the characteristic tangy flavor and texture of these foods by producing lactic acid. It can also be found in some fermented beverages and as a source of probiotics.

Lactococcus lactis subsp. is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) for use in food. It is often consumed as part of fermented foods and is considered a source of beneficial bacteria. International bodies like the European Food Safety Authority (EFSA) have evaluated similar lactic acid bacteria, often finding them to be safe for consumption. Evidence suggests these bacteria may contribute to gut health, though research is ongoing.
