Glucosidase from Aspergillus niger is widely used in the food industry for the hydrolysis of starch into simple sugars, enhancing the sweetness and texture of products like syrups and baked goods. In the brewing and fermentation industries, it aids in breaking down complex carbohydrates into fermentable sugars, improving alcohol yield and flavor profiles. This enzyme is also utilized in the production of bioethanol, where it converts cellulose into glucose, which is then fermented into ethanol. Additionally, it plays a role in the pharmaceutical sector for the synthesis of certain drugs and in research for studying carbohydrate metabolism. Its ability to efficiently break down glycosidic bonds makes it valuable in various biotechnological applications.
