This volume details methods and procedures used to detect and enumerate bacteria in food. Chapters guide readers through food and beverage matrices, techniques used to enumerate bacteria, mixed bacterial strains (naturally present or inoculated), yeast, viruses, protozoan in distinct food matrices, and freshwater.
Authoritative and cutting-edge, Detection and Enumeration of Bacteria, Yeast, Viruses, and Protozoan in Foods and Freshwater aims to provide a basic understanding on detection and enumeration of microorganisms in foods.
