【中文摘要】 采用变色圈和降解实验,结果显示供试的8个菌株均有降解云杉木屑中木质素和纤维素的能力,纤维素和木质素被食用菌降解的程度与被降解的次序无关。结果显示,用云杉木屑栽培榆黄蘑、金针菇和平菇菌株,其菌丝生长较快,生物转化率较高;茶树菇和杏鲍菇菌株的菌丝生长速度较慢,生物转化率较低;木耳、裂褶菌和柳蘑菌株,菌丝生长速度很慢,几乎无法正常出菇。上述食用菌菌株的生物转化率与其对木质素、纤维素降解率的总和呈正相关。
【英文摘要】 Circle discoloration and degradation experiments showed that all of 8 strains in the experiment have the ability to degrade lignin and fibrin of spruce chips, and the degradation degree of fibrin and lignin by edible fungi had nothing to do with the order of degradation. Cutltivation experiments showed that the mycelium of Pleurotus citrinipileatus, F. velatipes and Pleurotus ostreatus cultivated with spruce chips grew faster, and the change rate were higher. The mycelium of Agrocybe chaxingu and Pleurotus eryngii have general growth rate and lower change rate. The mycelium of Auricularia auricala, Schizophyllum commune and Pholiota adiposa grew very slowly. The biotransformation rate of edible fungi strains has the possitive correlation with the sum of lignin and fibrin degradation rate.
