中文摘要：
以黄孢原毛平革菌（Phanerochaete chrysosporium,Pc）为代表,研究了死体和活体Pc菌球对水中菲、芘等多环芳烃（PAHs）的生物吸附和生物降解作用及其相对贡献,探讨了碳源、氮源浓度和共存Cu2＋的影响,考察了连续多次输入下菲的生物吸附和生物降解作用,试图为准确掌握微生物作用下PAHs的迁移转化行为及其调控作用提供理论指导.结果表明,死体Pc菌球对水中菲、芘的去除机制为生物吸附,分配系数分别为4040和17500L/kg.活体Pc菌球的去除机制包括生物吸附和生物降解,3d时生物吸附对水中菲、芘的去除率分别为19.71%和52.21%;随着作用时间延长（3～40d）,生物降解对菲、芘的去除作用逐渐增大（20.40%～60.62%和15.55%～49.21%）,且菌体中PAHs残留量不断下降.富碳限氮营养条件下,活体Pc菌球对PAHs的去除作用和降解效果最优,在60d时分别为99.55%和92.77%（菲）,99.47%和83.97%（芘）,主要源于富碳增加Pc菌体生物量而增强生物吸附、限氮则触发Pc对PAHs的生物降解作用.活体Pc菌球在富碳限氮强化条件下可连续多次去除和降解新输入的PAHs,其中单次生物降解率随循环次数（6d/次）增加而增大,循环3次后菲的生物降解率高达90%.
