Microbial CultivationCliffsNotes
Microbial Cultivation. When microorganisms are cultivated in the laboratory a growth environment called a medium is used. The medium may be purely chemical (a chemically defined medium) or it may contain organic materials or it may consist of living organisms such as fertilized eggs. Microorganisms growing in or on such a medium form a culture.
