WebOn the basis of optimal growth temperature, thermophiles can be classified into three categories: moderate (50–64°C), extreme (65–79°C), and hyper (above 80°C) ( Eram and Ma, 2013 ). Longer half-life and high transition temperature allows the microorganisms to remain stable at high temperatures ( Satyanarayana et al., 2013 ). WebProteolytic types grow between 55 and 122 degrees F, with most rapid growth occurring at 95 degrees F. Nonproteolytic types grow between 38 and 113 degrees F, with an …
