Growth of obligate anaerobes. The mixture of necessary nutrients can be used as a liquid medium, or a solidifying agent can be added. Agar agar is a natural polysaccharide produced by marine algae and is the most commonly used solidifying agent added to media (end concentration usually 1.5 % w/v). If hydrolysis of the agar is suspected, a silica gel is used as a replacement solidifying agent.
These media contain antimicrobials, dyes, or alcohol to inhibit the growth of the organisms not targeted for study. Selective medium types include EMB agar, Mannitol Salt agar, MacConkey agar, and Phenylethyl Alcohol (PEA) agar.
