Research progress of fusion glycoside hydrolase in biomass conversion

The abundant biomass polysaccharides in nature can be degraded into oligo-oligosaccharides or monosaccharides. These sugars with small molecule used to produce ethanol, pharmaceutical products and other chemical materials. structure of plant is very complex, its degradation involves the synergistic catalysis various glycoside hydrolases, such as xylanase, glucanase, cellulose. Compared a single enzyme simple mixed enzymes, efficiency by fusion higher. expression level, activity stability could also improved choosing appropriate strategy construct enzyme. This achieve process integration when using energy substances materials, which would simplify production steps save costs. Therefore, hydrolase effectively solve bottleneck problem utilization biomass. article reviews research progress hydrolases modification technology, including construction strategies, capability application hydrolase, practical applications prospects for fundamental this field. It provides reference further development degradation.
