Catalog Number: | AS-1212
 
Dichloran Rose Bengal Chloramphenicol (DRBC) Agar is a selective culture medium designed to isolate and count yeasts and molds, especially in food samples. It is a variation of Rose Bengal Chloramphenicol Agar, adding dichloran to further inhibit fungal growth. The medium comprises peptone as a nitrogen source, dextrose as a carbon source, phosphate buffer, magnesium sulfate, and the selective agents dichloran and chloramphenicol and Rose Bengal. The acidic pH (5.6) favors yeast and mold growth while inhibiting many bacteria. The medium’s composition encourages distinct colony morphology, making counting easier.
