Description

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

Malt Extract Broth is recommended for the detection, isolation, and enumeration of fungi, particularly yeasts and molds, in various materials and for the cultivation of the strains for microbiological vitamin assays. This medium is suitable for nonselective cultivation of various fungal species, including Aspergillus spp., Candida spp., Penicillium spp., and Saccharomyces spp. It is used in food and beverage testing, environmental monitoring, and microbiological research.
