摘　　要：通过驯化、发酵筛选等方法,从供试的5株侧耳菌(Pleurotus)中选育到1株具有较高降解木质素的白腐类真菌P802,接种发酵10d后,木质素降解率为38%,对麦秸中纤维素降解率为8.10%。该菌株降解麦秸粉木质素的最适pH为4.0～4.5,最适温度30.4℃。A good Pleurotus ostreatus strain,P802,was obtained from the five acclimated Pleurotus strains by screening its capability in lignin degradation from wheat straws.The strain had the highest lignin degradation rate(38%) and the lowest cellulose degradation rate(8.10%) in wheat straw after 10 days fermentation at 30 ℃.The optimal degradable conditions of lignin was pH 4.0~4.5 at 30 ℃.
