| 英文摘要 | BACKGROUNDThe anoxygenic photosynthetic bacteria (APB) process is considered the most promising candidate for cost-effective wastewater treatment and resource recovery. One major problem in the APB process with sulfate-containing wastewater is the overgrowth of sulfate-reducing bacteria. In this study, the humic analog anthraquinone-2,6-disulfonate (AQDS) was used to selectively inhibit sulfate-reducing bacteria (SRB) in an SRB and APB coculture. RESULTSThe addition of 1.0mmolL(-1) AQDS to the SRB and APB coculture resulted in significant decreases in the amount of SRB and the sulfide concentration, whereas the number of APB increased from 3.7x10(3) to 3.1x10(8) CFU mL(-1). A high concentration of AQDS negatively affected the growth of both SRB and APB but more strongly inhibited the growth of SRB. The inhibition of SRB by AQDS relies on an electron donor and is enhanced by illumination. AQDS treatment at 1.0mmolL(-1) induced significant membrane depolarization and superoxide production in SRB cells but not in APB cells, and this may be responsible for the selective inhibition of SRB in the coculture. CONCLUSIONAt appropriate concentrations, AQDS can decrease the concentration of sulfide and induce oxidative stress for SRB, effectively allowing APB to out-compete SRB under microaerobic conditions.
