Principle
- Malt Extract Broth is recommended for the examination of yeasts and molds in the U.S. Food and Drug Administration’s Bacteriological Analytical Manual (2005). The media is composed of mycological peptone and malt extract. Mycological peptone provides nitrogen, vitamins, minerals, amino acids, and growth factors.
- Malt extract provides an energy source for the growth of microorganisms and provides an acidic environment for the growth of yeasts and molds. The low pH favors fungal growth and inhibits contaminating bacteria and makes it useful for cultivating fungi and aciduric microorganisms.
- Mycological peptone rapidly gives a luxuriant growth with typical morphology and pigmentation. Malt Extract Broth Base has been widely used in the maintenance, isolation, and identification of fungi and it is also proposed in several pharmacopeias as a medium for the control of sterility in pharmaceutical products, though it is mostly used for comparative morphological studies.
