Dichloran Glycerol (DG-18) Agar Base is used for the selective isolation and enumeration of yeasts and molds from foods in a laboratory setting. Dichloran Glycerol (DG-18) Agar Base is not intended for use in the diagnosis of disease or other conditions in humans.
Dichloran Glycerol Agar Base is based on the formulation by Hocking and Pitt. This medium is recommended for enumeration and isolation of yeasts and molds from dried and semi-dried foods, including fruits, spices, cereals, nuts, meat, and fish products. The highly selective composition of this medium allows for enumeration of fungal growth. In a comparative study between DG-18 Agar Base and DRBC Agar, greater recovery of two molds commonly isolated in high numbers from dried foods grew poorly on DRBC Agar.
A modification of DG-18 Agar Base, enhanced with Triton-X, is described as increasing inhibition of vigorously-spreading fungi.
