The Basic Xylanase (BAX) Activity Assay Kit is widely used in research and industrial applications to measure xylanase enzyme activity. It is essential in the biofuel industry, where xylanase enzymes break down xylan in plant biomass, facilitating the conversion of cellulose into fermentable sugars for ethanol production. In the paper and pulp industry, the kit helps optimize processes by monitoring xylanase activity, which improves pulp bleaching and reduces the need for harsh chemicals. Additionally, it is utilized in the food and feed sectors to enhance the nutritional value of animal feed by breaking down non-starch polysaccharides, improving digestibility. The kit also supports academic and biotechnological research focused on enzyme kinetics, protein engineering, and the development of efficient enzymatic processes.
