Cellulolytic enzymes are specialized proteins that break down cellulose, a complex carbohydrate found in the cell walls of plants. These enzymes play a crucial role in the digestion of plant materials, making them essential for various organisms, including fungi, bacteria, and some animals. By hydrolyzing cellulose into simpler sugars, cellulolytic enzymes facilitate the recycling of organic matter in ecosystems. In industrial applications, cellulolytic enzymes are used in processes like biofuel production, where they help convert plant biomass into fermentable sugars. They are also utilized in the textile and paper industries to improve the quality of products by breaking down cellulose fibers.
