PR1MA™ Malt Extract Agar, Powder
CAS Number: 8002-48-0
Solubility: Water with Heat
Storage Temp: Room Temperature
Malt Extract Agar is used for the isolation, cultivation, and maintenance of
yeasts and molds. Formulation is similar to Malt Extract Broth with the
addition of agar and glycerol. This broth medium was recommended by Thom
and Church for the cultivation of fungi. Its low acidity inhibits the
growth of most bacteria. The high carbohydrate content enhances the rapid
growth of fungi and yeasts.
