黄孢原毛平革菌对松木、稻草和芦苇去木质化作用的研究

为确定黄孢原毛平革菌对不同植物材料的去木质化作用，以pH、干物质重、半纤维素、纤维素和木质素为主要技术指标，比较黄孢原毛平革菌对松木、稻草和芦苇降解能力的差异。松木、芦苇在发酵过程中pH呈下降趋势，稻草呈上升趋势。在干物质重、半纤维素、纤维素降解率三个指标上皆为松木〈芦苇〈稻草，在木质素降解率上则为松木〈稻草〈芦苇，且差异显著。表明黄孢原毛平革菌对不同植物材料去木质化能力有较大差异，其中芦苇的木质素降解率为13％，是三种材料中最易于被去木质化的。

Study on Delignification of Pine,Rice Straw and Reed by Phanerochaete Chrysosporium

To study the delignification of Phanerochaete chrysosporium (BHK-F-1767) for different substrates, the marked changes of pH, weight loss, degradation of hemicellulose, cellulose and lignin in pine, rice straw and reed under solid-state fermentation were observed. The trends in the fermentations of pine and reed were toward lowering of pH, while that of rice straw was raised. Weight loss degradation rate of hemicellulose and cellulose is in the order: pine
