In the process of cheese making a “starter” culture of lactic acid bacterium,
Staphylococcus lactis, is added to the milk. The starter culture ferments the carbohydrates via
the glycolytic pathway to pyruvate, which is then reduced to lactic acid. The fermentation of lactose to lactic acid is fundamental to cheese making and is carried out by both
Streptococcus and Lactobacillus bacteria
