Microbial metabolism is the means by which a
microbe obtains the energy and nutrients (e.g.
carbon) it needs to live and reproduce. Microbes use many different types of
metabolic strategies and species can often be differentiated from each other based on metabolic characteristics. The specific metabolic properties of a microbe are the major factors in determining that microbe’s
ecological niche, and often allow for that microbe to be useful in
industrial processes or responsible for
biogeochemical cycles.
