Hemicellulase from Aspergillus niger is widely used in various industries due to its ability to break down hemicellulose into simpler sugars. In the food industry, it is employed to improve the texture and clarity of fruit juices by breaking down polysaccharides, enhancing filtration and stability. It also plays a role in baking, where it modifies dough properties, improving volume and texture of baked goods.

In the biofuel sector, this enzyme is crucial for the pretreatment of biomass, converting hemicellulose into fermentable sugars for ethanol production. Additionally, it is used in animal feed to enhance digestibility and nutrient absorption by breaking down complex plant fibers.

In the paper and pulp industry, hemicellulase aids in the bleaching process, reducing the need for harsh chemicals and improving paper quality. Its versatility makes it a valuable tool in biotechnology and industrial processes.
