摘要: 为提高有害物质2,4,6-三溴苯酚(TBP)的有效生物降解效果,在比较了不同菌株对TBP的降解状况的基础上,着重考察了诱变菌株TBPY UMP-f与粘质沙雷氏菌株SMA混合降解TBP的效果.结果表明,混合菌株比单一菌株降解效果好.考察影响混合降解相关因素的结果表明,适宜条件为两菌接种比例1∶1,SMA适于在TBPY UMP-f接种22 h后添加,最适pH 7.0,温度30 ℃,装液量60 mL,摇床转速175 r·min-1.在此条件下,作用2 d混合菌株对100 mg·L-1 TBP的降解率达到96.5%.在研究范围内,混合降解TBP的浓度可达600 mg·L-1,是已知报道的2倍,且4 d内降解率可达65.3%.

Abstract: In this paper, in order to find an effective biodegradation treatment for harmful substance 2,4,6-tribromophenol (TBP), the effect of TBP biodegradation with mixed strains (Pseudomonas aeruginosa TBPY UMP-f and Serratia marcescen SMA) was investigated extensively, based on the comparison of TBP degradative ability with different strains. Some factors on the TBP biodegradation with the mixed strains were studied, and the results showed that TBP degradation with the mixed strains was better than the single strain. Under the optimal conditions of the inoculation proportion of TBPY UMP-f and SMA 1∶1, the interval inoculation time of SMA 22 h, the temperature 30 ℃, the liquid volume 60 mL, the shaker rotary speed 175 r·min-1, the degradation rate for 100 mg·L-1 TBP in 2 days reached 96.5%. In addition, the mixed strains degraded TBP with concentration of 600 mg·L-1, which was twice as much as that reported before, and TBP degradation rate in 4 days was 65.3%.
