Xylanases are crucial hydrolase enzymes that catalyze the breakdown of β-1, 4 glycosidic bonds of the xylan backbone polymeric chain that comprises xylose monomers. There are a variety of industrial implementations as commercial enzyme for heat-stable xylanase. Thermostable xylanases were utilized in a wide range of industries, for instance, in the pulp and paper industry industries; biofuels; and food and feed manufacturing industries; and textiles industries. Improvement of the thermostability of xylanase employed commercially or industrially will improve their efficiency and business success due to improved enzymatic abilities and cost-effectiveness. This study discusses the development of xylanases industrial stability. Even the different approaches of protein engineering and metabolic engineering were developed to enhance the operational stability of xylanase. To improve the nutrient content of livestock feed, thermostable xylanases have been reported. We do have employed directly in bakeries and breweries including significant use as a bio-bleaching agent in the paper and pulp industries. This review focuses on a few uses of thermostable xylanase in bioengineering.
