Beschreibung

General description

Malt Extract Broth is a liquid culture medium specifically designed for the cultivation of yeasts and molds. It contains malt extract and mycological peptone, which provide essential nutrients for fungal growth. Malt extract contains polysaccharides, which are used as an energy source. It also makes the medium acidic. Mycological peptone serves as a nitrogen source. Lactic acid, tartaric acid, or antibiotics suppress bacterial growth, making the medium more selective. Reiss recommends a modified malt extract medium for the selective cultivation of Aspergillus flavus. According to Rapp, the addition of certain indicator dyes to malt extract agar allows differentiation of yeast and bacterial colonies.

Application

Flüssigmedium zur Kultivierung von Hefen und Schimmelpilzen.
