Research on microorganism xylanases and their applications
Xylan is the major constituent of hemicelluloses. Due to the structural heterogeneity of the xylans, xylan-degrading enzyme systems include several hydrolytic enzymes. Xylanase(EC 3.2.1.8,1,4-β-D-xylanase)can hydrolyze β-1,4-glycosidic linkages of the xylan backbone to produce short chain xylooligosacchrides of various lengths. Hence, endo-β - xylanase is the crucial enzyme component of microbial xylanolytic enzyme systems. And the microorganism xylanases system, classification, source and distribution were summarized. The microorganism xylanases including their properties, production and their applications in food, papermaking, feed industries were reviewed.
