WebSpore-forming bacteria are ubiquitous in nature. The resistance properties of bacterial spores lie at the heart of their widespread occurrence in food ingredients and foods. Webfour types of spores are produced by a number of representative groups of bacteria. The most widely studied are the endospores, which are found in three genera—Bacillus, Clostridium and Sporosarcina.Endospores are essentially dormant or resting cells and their formation does not represent a reproductive process.
