主　　题：biodegradation biostimulation catechol 2,3-dioxygenase enzyme activity polycyclic aromatic hydrocarbons 

摘      要：Bacterial-feeding nematodes can promote the bacterial activity through *** abundance and their activity affect the degradation of polycyclic aromatic hydrocarbons(PAH) such as *** effects of bacterial-feeding nematodes,bacteria,and their interactions on the degradation of phenanthrene with or without glucose were studied through a microcosm *** results showed that up to 57.0%of phenanthrene in mineral medium contaminated with phenanthrene was degraded in the control with bacteria alone and bacteria with the presence of nematodes and/or glucose increased the degradation of phenanthrene by 25.6%to 36.6%.Although both nematode and bacteria abundance decreased gradually,catechol 2,3-dioxygenase(C230) activity increased during the incubation *** with bacteria alone,the presence of nematodes significantly increased C230 activity as well as the abundance of bacteria;this effect was more pronounced when glucose was *** results imply that nematodes might promote the removal of phenanthrene from medium by stimulating bacteria and C230 activities.
