| 英文摘要 | It is neither comprehensive nor appropriate that the bioremediation of a benzo[a] pyrene (BaP)-contaminated environment be assessed only by its high degradation extent because its metabolites' chemical structures are similar to the parent compound and maybe equally toxic. Therefore, further degradation of BaP metabolites is significant. Three methods, combining the Zoogloea sp. with potassium permanganate, combining the Zoogloea sp. with H2O2, Zoogloea sp. alone, were investigated to degrade cis-BP4,5-dihydrodiol and cis-BP7,8-dihydrodiol, which are the metabolites of BaP formed by bacterium-Zoogloea sp. Optimum parameters of degradation in the best method are that: of the three methods, coupling the Zoogloea sp. and KMnO4 is the best; compared with cis-BP7,8-dihydrodiol, cis-BP4,5-dihydrodiol is the more liable to be accumulated in pure cultures; the degradation effect of the two metabolites is optimal when the initial concentration of KMnO4 in the cultures is 0.05%; initial concentration of cis-BP4,5-dihydrodiol and cis-BP7,8-dihydrodiol is 4 mg L-1, 8 mg L-1, respectively; cometabolic substance is salicylic acid or sodium succinate. The degradation extent of cis-BP 4,5-dihydrodiol and cis-BP 7,8-dihydrodiol using combining the Zoogloea sp. and KMnO4 reach 76.1% and 85.9% after 12 days of cultivation, respectively, which were more than twice compared with conventional method. |
