This is a medium for the cultivation of yeasts and moulds. The high carbohydrate content is said to ensure rapid growth while the low pH (5.4) inhibits most bacteria. Malt Extract Agar can also be used for the cultivation of fungi although with the prolonged incubation necessary cultures may become overgrown by bacteria. -
Malt Extract Agar is a medium for the isolation of many yeasts and moulds. The low pH inhibits most bacteria and further selectivity can be achieved by lowering the pH even more by adding lactic acid to the molten cooled, medium. This formulation is customer specific with a request for an additional 5g/L of agar from the customer. It should be noted that excess heating of the medium could result in hydrolysis of the agar resulting in softening of the agar.
