The food industry must always be vigilant for bacteria that can survive the methods they try to use to keep the food safe. Let’s
explore that a little in this question. A. There’s always danger from psychrophiles or facultative psychrophiles. How have these bacteria adapted to survive in their environment?
Psychrophile is a type of organism and bacteria that can grow and reproduce in very low temperatures. Besides low and cold temperatures these organisms adapt to high pressure and high concentrations of salt. Their body has adapted to these types of harsh environments by having a body that keeps them from freezing. Their enzymes had evolved to engage in activities such as activity-stability-flexibility as a method for adapting to the cold. This type of bacteria can grow in refrigerated temperatures and they could be found in foods and dairy products.
Selective breeding involves choosing parents with particular characteristics to breed together and produce offspring with more desirable characteristics. Humans have selectively bred plants and animals for thousands of years including: crop plants with better yields.
