【中文摘要】 采用變色圈和降解實驗,結(jié)果顯示供試的8個菌株均有降解云杉木屑中木質(zhì)素和纖維素的能力,纖維素和木質(zhì)素被食用菌降解的程度與被降解的次序無關(guān)。結(jié)果顯示,用云杉木屑栽培榆黃蘑、金針菇和平菇菌株,其菌絲生長較快,生物轉(zhuǎn)化率較高;茶樹菇和杏鮑菇菌株的菌絲生長速度較慢,生物轉(zhuǎn)化率較低;木耳、裂褶菌和柳蘑菌株,菌絲生長速度很慢,幾乎無法正常出菇。上述食用菌菌株的生物轉(zhuǎn)化率與其對木質(zhì)素、纖維素降解率的總和呈正相關(guān)。

【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.
