Used as a culture medium in microbiology for cultivating microorganisms that require starch as a carbon source. Supports the growth of bacteria and fungi capable of producing amylase enzymes, which break down starch into simpler sugars. Commonly used in laboratory testing to identify starch-hydrolyzing microbes through iodine staining, where a clear zone around microbial growth indicates starch degradation. Also utilized in industrial fermentation processes for screening enzyme-producing strains.
