Temperature and microbial growth
WebThis encourages growth of the culture without growing human pathogens which thrive at body temperature (37°C). For safety reasons, plates and equipment should be sterilised … WebAnswer (1 of 3): Microbes lack high defined homeostasis. Thus, they cannot regulate their internal temperature and are susceptible to environmental changes. The increase or decrease in the temperature of the surrounding affects the enzyme-catalyzed reaction. Below the optimum temperature range, t...
