說明
一般描述
Potato Dextrose Agar is recommended for the isolation ａnd enumeration of yeasts ａnd molds in dairy ａnd food products. Potato extract serves as a source of carbon, nitrogen, minerals, vitamins, ａnd other essential growth nutrients. Dextrose acts as a source of carbohydrates. Agar is the solidifying agent. The accompanying bacterial flora is suppressed by the low pH of 3.5. The growth of yeasts ａnd molds is promoted in this medium, ａnd the fungi develop typical morphology. The addition of Rose Bengal further suppresses the growth of bacteria ａnd restricts the size ａnd spreading of mold colonies.
