Rose Bengal Agar Base is used in isolating and enumerating yeasts and molds. Used in combination with Rose Bengal Antimicrobic Supplement C.

Principles Peptone provides the carbon and nitrogen sources required for good growth of a wide variety of organisms. Dextrose is an energy source. Monopotassium phosphate provides buffering capability. Magnesium sulfate provides necessary trace elements. Rose bengal is included as a selective agent that inhibits bacterial growth and restricts the size and height of colonies of the more rapidly growing molds. The restriction in growth of molds aids in the isolation of slow-growing fungi by preventing overgrowth by more rapidly growing species. Rose bengal is taken up by yeast and mold colonies, thereby facilitating their recognition and enumeration. Rose Bengal Antimicrobic Supplement C (not included, sold separately) is a lyophilized antimicrobic supplement containing chloramphenicol which inhibits bacteria. Agar is the solidifying agent.
