Thermophilic spore formers
WebbSpore-forming bacteria are heat-resistant microorganisms capable of surviving and germinating in milk after pasteurization. They have been reported to affect the quality of dairy products by the production of enzymes (lipolytic and proteolytic) under low-temperature conditions in fluid milk, and hav … Webb1 dec. 2024 · Spore formers are prevalent in dairy environments and are common spoilage-causing microflora in milk and dairy products. Their spore-forming ability increases their survivability during heat treatment, which leads to their presence in pasteurized products.
