Degradation with an aerobic consortium was used to evaluate the bioremediation trichloroethylene (TCE) as a model substrate. After one week, 228-1186 mg TCE l(-1) was degraded at rates of 20-50 microg TCE l(-1) h(-1). The introduction of 10 mg toluene l(-1) enhanced the degradation rates for TCE when greater than 600 mg l(-1). Using isolated enzymes, a TCE degradation intermediate(s) appears inhibitory to the oxygenase enzymes thereby diminishing the overall degradation.
使用好氧菌群进行降解,以三氯乙烯(TCE)作为模型底物来评估生物修复效果。一周后,228 - 1186毫克/升的三氯乙烯以20 - 50微克/升·小时的速率被降解。当三氯乙烯浓度大于600毫克/升时,添加10毫克/升的甲苯可提高其降解速率。使用分离出的酶时,三氯乙烯降解中间产物似乎对加氧酶有抑制作用,从而降低了整体降解效果。
