Environmental microbiology, in comparison, relates primarily to all- over microbial processes that occur in a soil, water or food, as examples. It is not concerned with the particular microenvironment where the microorganisms actually are functioning, but with the broader-scale effects of microbial presence and activities

Metabolically related populations constitute groupings called guilds. Sets of guilds conducting complementary physiological processes interact to form microbial communities. In a microbial ecosystem individual cells grow to form populations
