Encyclopedia Article for culture medium

solution freed of all microorganisms by sterilization (usually in an autoclave, where it undergoes heating under pressure for a specific time) and containing the substances required for the growth of microorganisms such as bacteria, protozoans, algae, and fungi. The medium may be solidified by the addition of agar.

These include enriched media, which contain nutrients in addition to those found in the usual growth medium, and selective media, which contain substances that prevent the growth of certain organisms but not others
