废菌糠及其辅料对香菇培养料中木质纤维素降解的影响

香菇培养料中含有２０％的废菌糠。在营养生长阶段可以加速木质纤维素复合体的解体，并将木质纤维素的降解率提高７％以上，辅料中还原糖和氮素的含量水平不同，木质纤维素率也不同，从１７．５０％到２０．１２％不等，辅料２＃对木质纤维素降解促进作用最明显，辅料３＃次之，辅料１＃和辅料４＃相近，为最低。

Effect of Spent Artificial Log and Supplement on Biodegradation of Lignocellulose in the Substrate of L. edodes

The decomposition of the lignocellulose complex was sped up, while the lignocellulose biodegradation rate (LBR) was increased over 1% by 20% spent artificial log in the substrate of L. edodes at mycelial growth stage. The LBR affected by the content of reductic sugar and nitrogen in supplement varied from 17.50% to 21.12% resp.. It was found that the LBR of the substrate with supplement 2* was the highest, followed by the substrate with supplement 3, and that the LBR of the substrate with supplement 4* and 1* was at the lowest level.
