Description
DRBC Agar Base is a selective medium for enumerating yeasts and moulds.
Dichloran restricts colony spreading, rose bengal limits rapidly growing moulds and bacterial growth, and chloramphenicol further suppresses accompanying bacterial flora. Yeast colonies may take up rose bengal and appear pink.
The PDF describes surface inoculation followed by aerobic incubation at 25°C for up to five days, with daily examination beginning after two days.
