Effect of Carbohydrates on Protease and Lipase Production in Seed-Borne Fungi of Soybean

During the process of biodeterioration, seed mycoflora produce enzymes to degrade protein, carbohydrate and oil. These enzymes are called as hydrolytic enzymes. The enzymes which degrade proteins are called protease and enzymes, which degrade oil are lipase. Among the protease activity, most of the monosaccharides and disaccharides stimulate protease production; however, among monosaccharides are xylose-inhibited protease activity of Alternaria alternata and Aspergillus flavus. Fructose-inhibited protease activity of Aspergillus glaucus. Among disaccharides, only maltose-inhibited protease production of Aspergillus flavus and A. niger.
