The lignin, cellulose and hemicellulose contained in corn straw need to be degraded before reuse. Therefore, it is urgent to explore a new strategy that can enhance the degradation effect of lignin, cellulose and hemicellulose. is one of the corn pests feeding on corn straw, which can degrade and consume corn straw by digestive enzyme secreted in the midgut. Herein, the degradation efficiency of lignin, cellulose and hemicellulose was tested by a stain of white rot fungus combined with digestive enzyme of extracted from its midgut. It was proved that the selected strain of white rot fungus could degrade lignin, cellulose and hemicellulose effectively. The contents of lignin, cellulose and hemicellulose decreased with the extension of degradation time, with the lowest level reached at 35 d with 9 ml digestive enzyme solution of added. Compared with the control group, digestive enzyme of could improve the degradation effect of the selected white rot fungi on lignin, cellulose and hemicellulose. The effect of degradation was enhanced with the extension of degradation time and the increase in the amount of digestive enzyme added. The results provide a new strategy and a basis for strengthening the degradation effect of white rot fungi on corn straw.
玉米秸秆中含有的木质素、纤维素和半纤维素在再利用之前需要进行降解。因此，迫切需要探索一种能够提高木质素、纤维素和半纤维素降解效果的新策略。[某种生物]是一种以玉米秸秆为食的玉米害虫，它可以通过中肠分泌的消化酶降解和消耗玉米秸秆。在此，通过一种白腐真菌菌株与从其中肠提取的[某种生物]消化酶相结合，测试了木质素、纤维素和半纤维素的降解效率。结果证明，所选的白腐真菌菌株能够有效降解木质素、纤维素和半纤维素。随着降解时间的延长，木质素、纤维素和半纤维素的含量降低，在添加9毫升[某种生物]消化酶溶液的情况下，35天时达到最低水平。与对照组相比，[某种生物]的消化酶能够提高所选白腐真菌对木质素、纤维素和半纤维素的降解效果。随着降解时间的延长和消化酶添加量的增加，降解效果增强。这些结果为增强白腐真菌对玉米秸秆的降解效果提供了一种新策略和依据。
