中文摘要：

对水体／沉积物中蒽的生物降解及铜的生物吸附作用进行了研究。烟曲霉A10对蒽、铜有良好的降解、吸附能力。水体中，蒽的质量浓度为10mg／L时，铜的质量浓度的增加导致其吸附率降低，但均处于80％以上；当铜的质量浓度处于0．60-6．09mg／L时，蒽降解率从62．01％升至82．45％，之后随铜的质量浓度的升高而下降。沉积物中，铜的质量浓度的变化对蒽降解的影响与水体中的情况类似，但蒽降解率总体高于水中的情况；蒽质量浓度的增加对铜吸附率无明显影响，均维持在95％以上，而蒽降解率在其初始质量浓度为5mg／L时最大，达88．09％，之后趋于下降。一定质量浓度的铜在一定程度上对蒽降解有促进作用，但铜质量浓度过高会使降解率下降。铜吸附率和蒽降解率均随蒽质量浓度的提高而下降，其中蒽降解率降幅较大，铜吸附率只有微弱变化。

英文摘要：

Biodegradation of anthracene and biosorption of Cu in water and sediment were investigated. The strain Aspergillus furnigatus A10 exhibited excellent ability of anthracene degradation and Cu sorption. When the concentration of anthracene in water was 10 mg/L, the biosorption rate of Cu decreased with its increasing concentration, but all exceeded 80%. On the other side, the biodegradation rate of anthracene rose from 62. 01% to 82.45% with the concentration of Cu ranging from 0. 60 mg/L to 6.09 rag/L, then, the biodegradation rate declined when concentration of Cu continued to increase. The similar phenomena occurred when it came into sediment, however, the biodegradation rate of anthracene was higher. The increase of concentration of anthracene in sediment had no significant influence on Cu biosorption rate which maintained over 95%. But biodegradation rate of anthracene was the highest （88.09%） with its initial concentration of 5mg/L, and then it tended to drop down. Certain concentration of Cu could favor the biodegradation of anthracene to some extent, however, the excessive amount of Cu couId result in the decrease of biodegradation rate. The biosorption of Cu and biodegradation of anthracene both decreased with the increasing concentration of anthracene, among which the biodegradation of anthracene had a greater reduction compared with the weak variation of Cu biosorption rate.
