| Abstract: | Despite its simple chemical composition,cellulose exists in a number of crystalline and amorphous topologies.Its insolubility and heterogeneity makes native cellulose a recalcitrant substrate for enzymatic hydrolysis.On the basis of the hydrolysis of cellulosic biomass,in this review the basic research on crystalline cellulose-degrading enzyme was concerned.Main avicelase-producing organisms were described.A mechanistic model for the action of enzyme complexes on the surface of insoluble substrates,some opportunities of cellulase improvement by means of gene and protein engineering and its biotechnological perspectives were discussed. |
