Product number: NCM0132

OGYE Agar Base is used with oxytetracycline in the detection and isolation of yeasts and molds from foods. OGYE Agar Base is not intended for use in the diagnosis of disease or other conditions in humans.

A selective medium for the enumeration of yeasts and molds in food, introduced by Mossel in 1970. Unlike many selective media for yeasts OGYE has a neutral pH and it has been shown to give better recovery rates than those media with a low pH. Oxytetracycline is used to inhibit bacteria and certain high protein foods may reduce the effectiveness of this antibiotic as a selective agent. Rose Bengal Chloramphenicol Agar (NCM0135) is recommended in these instances.
