摘要(Abstract)：

从胶州湾湿地污染土壤中筛选出2株BaP降解菌—JB1和JB2,以改性煤渣、改性PVA为载体材料,将JB1、JB2混合菌通过包埋的方式制成固定化生物煤渣球并投加到种植了芦苇的BaP污染土壤中进行室外降解实验,42d后,BaP的降解率达到69.3%,降解效果好于生物煤渣球或芦苇单独作用时的降解效果。投加固定化微生物后,土壤中微生物群落的多样性明显减少,细菌的群落结构以PAHs降解菌为主,如Pseudomonas sp.,Mycobacteriumsp.,Achromobacter sp.;降解结束18d后,土壤中微生物群落的多样性增加,细菌的群落结构也得到一定程度的恢复。

关键词(KeyWords)： 苯并[a]芘;固定化微生物;芦苇;多样性;群落结构
