How does Lactobacillus bulgaricus function as a catalyst?
In the context of biocatalysis, Lactobacillus bulgaricus acts as a biological catalyst by accelerating the fermentation process. During fermentation, this bacterium produces enzymes that break down lactose into glucose and galactose, which are then further converted into lactic acid. This conversion is essential for the thickening and souring of milk, resulting in the formation of yogurt. The lactic acid produced lowers the pH of the milk, which inhibits the growth of harmful bacteria and extends the shelf life of the product.
