Abstract: Efficient degradation and conversion of the polysaccharides in the plant cell wall of straw is of great significance for green and sustainable development of agriculture economy in China. But the enzymatic hydrolysis process of the polysaccharides was restricted by the complex structures of plant cell wallsformed in the long-term evolution process. In this paper, the diversity of plant cell wall polysaccharides synthetases, the complexity of cell wall polysaccharides, and the heterogeneity of supramolecular structures are reviewed from the perspective of the reasons causing plant cell wall recalcitrance;in addition, the variety of plant cell wall degradation enzymes of fungi, and the discrepancy among different strains in degrading different biomass were also summarized, which provide theoretical support for reasonable recompounding of fungi degradation enzymes in industrial to improve the utilization efficiency of straw biomass.

Key words: plant cell wall, recalcitrance, polysaccharides synthetases, fungi degradation enzymes, green and sustainable development
