👉 Pectinibranchia, also known as pectinizing bacteria, is a type of organism that plays an important role in the fermentation process. These bacteria are responsible for breaking down plant cell walls and producing enzymes that aid in the production of lactose, which is a common byproduct of cheese-making. Pectinibranchia can be found in many different types of foods, including milk products, yogurt, and kefir.
