| Abstract: | The xylanase system of microbes is an important tool to investigate the use of the second most abundant poly saccharide (xylan) in nature. Recent studies on microbial xylanolytic systems have generally focused on induction of enzyme production under different conditions, purification, characterization, gene cloning and expression, and use of enzymes predominantly for pulp bleaching. This review highlights complex xylan structure, microbial xylanolytic enzymes including their biosynthesis, immobilization, solid state fermentation, synergistic action, and molecular cloning of the genes as well, with special reference to application in biobleaching. |
