Product Overview

Lactococcus lactis is a well-known lactic acid bacterium central to the fermentation of dairy products. When introduced into milk, it converts lactose into lactic acid, acidifying and coagulating the milk to form curds that are further processed into cheese and whey. In addition to its long-standing use in dairy fermentation, Lactococcus lactis is also valued as a beneficial probiotic with potential health-supporting properties.
