What is microbial growth? - increase in the number of cells What are the two general requirements for microbial growth? - physical: temperature, pH, osmotic pressure chemical: types of nutrients, growth factors A bacterium has just encountered a new environment. What are its three basic choices with respect to growth in this new environment? - Adapt- allows growth to continue Tolerate- survive without growth DIE What are a bacterium's cardinal temperatures? Do all bacteria have the same...

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...
