WebbStarch mites are too large at enter the infectious cell, so only fungus that secrete exoenzymes (α -amylase and oligo-1,6-glucosidase) are able to hydrolyze starch into subunits (dextrin, maltose, or glucose). These molecules are readily transported into the biological cell to must used in metabolism.

WebbAn amylase ligand-binding assay was used to assess the expression of AbpA in culture supernatants and on bacterial cells from S. gordonii grown in defined medium supplemented with 1% starch, 0.5 mg ml(-1) amylase, with starch and amylase together, or with various linear malto-oligosaccharides. WebbAlpha-amylase is an enzyme that breaks down starch molecules into smaller components such as glucose and maltose. These smaller components can then be fermented by yeast to produce carbon dioxide gas which is essential for dough expansion and helps to create a fluffy texture in baked goods.
