Fungi can produce enzymes called cellulases that break down cellulose in agricultural waste into sugars. This process is important for making biofuels, paper, and other products. Using solid-state fermentation, fungi can efficiently make cellulases from agricultural waste. This method is cost-effective and environmentally friendly. By using different parts of plants, fungi can produce a complete set of cellulase enzymes. This research shows that fungi are a good source of cellulases for converting agricultural waste into useful products.
