Quick Answer: What are five environmental conditions that effect the growth of microorganisms and how does each one specifically effect microbial growth?

The rate of growth or death of a particular microbial species is influenced by a variety of physical factors in its environment including temperature, osmotic pressure, pH, and oxygen concentration.

What are five environmental conditions that affect the growth of microorganisms and how does each one specifically affect microbial growth?

There are a variety of environmental factors that affect microbial growth. The most important physical factors are pH, temperature, oxygen, pressure, and salinity. pH measures how acidic or basic (alkaline) a solution is, and microbes may grow in either acidic, basic, or neutral pH conditions.

What are the environmental conditions that support the growth of bacteria?

Bacteria can live in hotter and colder temperatures than humans, but they do best in a warm, moist, protein-rich environment that is pH neutral or slightly acidic. There are exceptions, however. Some bacteria thrive in extreme heat or cold, while others can survive under highly acidic or extremely salty conditions.
