Description

General description

ReadyPlate^™ CT DG 18 Agar contact plates provide a ready-to-use method for environmental monitoring of surfaces in critical clean rooms and isolators. Dichloran Glycerol Medium is recommended for the isolation and enumeration of xerophilic molds from dried and semi-dried foods. The glycerol at 18% (w/w) lowers the water activity (aw) from 0.999 to 0.95 without causing any problem. Peptone provides carbon, nitrogen, vitamins, and minerals. Dextrose (Glucose) is a carbohydrate source. Phosphate buffers the medium. Magnesium sulfate provides divalent cations and sulfates. Dichloran is an antifungal agent added to the medium to reduce colony diameters of spreading fungi. Chloramphenicol is included to inhibit the growth of accompanying bacteria in the sample. Inhibiting the growth of bacteria and restriction of colony diameter of more-rapidly growing molds helps in the isolation of slow-growing fungi by preventing their overgrowth by more-rapidly growing species

Application

ReadyPlate^™ CT Dichloran Glycerol Chloramphenicol Glucose Agar is used for the enumeration of yeast and molds from food and environmental samples with less water activity.
