摘　　要：研究平菇诱变菌株(Pleurotus ostreatus SG0056)去除菲的效果、生物降解特性,并考察不同金属离子、诱导物对菌株培养过程中漆酶的影响。结果表明:(1)Pleurotus ostreatus SG0056菌体对菲有一定的吸附作用,但贡献较小,漆酶在菲的生物降解过程中促进作用显著。(2)Cu^(2+)和木质素对漆酶分泌有明显促进作用。(3)Pleurotus ostreatus SG0056对菲的代谢途径存在多种可能。The phenanthrene removal performance,biodegradation characteristics and effects of different metal ions and inducers on laccase activity during fermentation of Pleurotus ostreatus SG0056 were observed.The results showed that:(1)Pleurotus ostreatus SG0056 had little effect on phenanthrene adsorption,biodegradation played a major role,the mycelium had some effects on phenanthrene biodegradation.(2)Laccase activity could be stimulated by Cu 2+and lignin significantly.(3)There were many possible metabolic pathways of phenanthrene by Pleurotus ostreatus SG0056.
