What are the physical requirements for microbial growth? Temperature, pH, and osmotic pressure Temperature Most microorganisms grow well at the temperatures that humans favor; but there are three major ranges of temperature: psychorophiles, meosphiles, thermophiles psychorophiles cold-loving microbes (-10 to 20) Mesophiles moderate-temperature loving microbes (10 to 50) Thermophiles heat loving microbes (40 to 73) Maximum growth temperature highest temperature at which growth is possi...
