Abstract:It is the main trend of green and energy saving utilization of resources to degrade cellulose, lignin and other polymers by using active enzyme system produced by microorganisms. In this study, XLGL201709099 and XLGL201709112 were isolated from Xilingol area and identified by ITS sequence analysis. Four different solid media were used, and the growth capacity and final biomass of mycelia were used as evaluation indexes to screen the optimal solid media. The total antioxidant capacity(ABTS) and filter paper enzyme activity(FPA) of two strains of trichoderma were determined respectively to evaluate the laccase and cellulase production capacity. The results showed that XLGL201709099 was the Trichoderma aureoviride strain, and GPY was the optimal solid medium. The laccase production activity of the strain was 6.319 U/L, and the total cellulase activity was 0.538 U/g.XLGL201709112 was the Trichoderma koningii strain, and GPY medium was the optimal solid medium. The laccase production activity of the strain was 6.138 U/L, and the total cellulase activity was 0.888 U/g. The laccase and cellulase production capacity of two strains of trichoderma were studied in order to provide useful reference for the degradation of cellulose and lignin in this area.
