Webbpsychrotrophic bacteria in the dairy industry are also described. Psychrotrophic bacteria Psychrotrophic bacteria are not the specific taxonomic group of microorganisms, but are defined as group of different bacterial species that are able to grow at 7 °C or less regardless of their optimal temperature of growth (IDF Bulletins, 1976). WebbThe thermophiles are the microorganisms that grow at high temperature of 55°C or more (min. 45°C, optimum between 55-65°C, maximum 80°C). Some micro-organisms grow even at more high temperature, the optimum between 80°C and about 113°C, and are called hyper-thermophiles. The later usually do not grow well below 55°C.
