Progress in research on molecular modification of xylanase thermostability

Xylanase has been widely used in the processing of food, pharmaceuticals, the clarification of wine, the bleaching of pulp and other industries, of which the thermostability plays a vital role in its application in industrial field.According to the catalytic domain of amino acid composition, xylanase is divided into F / 10 and G / 11 families. This article summarizes the method and technique for molecular modification of xylanase thermostability of the two families and provides a reference for further improvement of the thermostability.
