鲤鱼肠系微生物对2,4-二硝基甲苯的还原代谢

Reduction metabolism of 2,4-dinitrotoluene by the intestinal microorganisms of carp

通过体外实验研究2,4-二硝基甲苯(2,4-dinitrotoluene 2,4-DNT)在鲤鱼肠系微生物作用下的还原代谢规律,探讨了2,4-二硝基甲苯的初始浓度、温度、肠系微生物量等因素对2,4-二硝基甲苯的生物转化的影响.结果表明,鲤鱼肠系微生物对2,4-二硝基甲苯具有代谢作用,2,4-二硝基甲苯适宜的代谢浓度为10.92mg/L,适宜的代谢温度为20℃,肠系微生物量以10mg/mL为佳.

The regularity of reduction metabolism of 2,4-dinitrotoluene (2,4-DNT) by the intestinal microorganisms of carp was studied through external experiment. The effects of 2,4-DNT concentrations, temperature, intestinal microorganisms content on biotransformation of 2,4-DNT were discussed prelimilarily. The results showed that 2,4-DNT was metabolized by intestinal microorganisms of carp. The optimal concentration of 2,4-DNT for metabolism was 10.92mg/L, the optimal temperature was 20℃ and the optimal intestinal microorganisms content was 10mg/mL.
