摘要：The impact of the bio-pretreatment for Larix kaempferi was assessed after its exposure to three white-rot fungi, namely Corticoid caeruleum, Het-erobasidion insulare^ and Pseudotrametes gibbosa. Their changes in chemical composition and microstructure, as well as their predisposition to enzymatic saccharification and wood decomposition were investigated. Three white-rot fungi were tested. H. in-sulare selectively reduced this wood lignin and cellulose, instead of the whole assembly. After an 8-week pretreatment with H. insulare, the weight loss was 10.7%, and the test sample of lignin lost 14.52%. In comparison, all cellulose was lost due to C. caer-uleum and P. gihhosa by 7.81% or less. Data show that the enzyme secreted outside exhibits cellulase from H. insulare concentrations higher than other strains of white-rot fungi. Thus, lignin and cellulose activities depend on the total weight loss of L. Besides, kaempferi and other chemical composition of the sample with three white-rot fungi showing good correlation. According to the experimental analysis, X-ray diffraction (XRD) and pore size distribution of the sample timber obtained from the degradation of the physical data reported an optimistic forecast of H. insulare; these could be processed using potential fungal strain targets through woody biomass pretreatment. Compared with the non-disaccharide yield, pretreatment with a control sample greatly increased to 21.01%. Experimental results also show that white-rot fungal strain H. insulare in the lignin degradation process does not provide the necessary biomass. Nevertheless, disaccharide provides an effective method.
