Cellulase is a crucial enzyme utilized in various industries, including biofuel production, textile processing, and animal nutrition. This enzyme plays a pivotal role in breaking down cellulose, a major component of plant cell walls, into simpler forms such as glucose. In animal agriculture, cellulase is included in feed formulations to improve the digestibility of fibrous feed ingredients like grasses, soybean hulls, and corn stover, thereby enhancing nutrient availability for livestock and poultry. By promoting efficient fiber digestion, cellulase serves as an essential component in animal nutrition and feed manufacturing.
