【摘要】 经过驯育得到具有降解芳香硝基化合物能力的混合菌群及6种单一菌株。在好氧条件下,芳香硝基化合物浓度为600mg/L肘,混合菌群对其降解率,24h为77.6％,48h为88.2％以上。而6种单一菌株对芳香硝基化合物的降解率,48h均在20.0％～21.6％间。该驯育菌群降解芳香硝基化合物的适宜条件为:好氧.温度25～30℃,不加外源碳、氮营养,只加少量磷酸盐及镁盐。更多还原

【Abstract】 The bacterial mixed population and six strains isolated from the ditch deposit were domesticated,and the bacteria could degradate the nitroaromatic compounds. Under air condition, when the concentration of nitroaromatic compounds in wastewater was 600 mg/ L,the rate of degradation was 77. 6% within 24 h and 88. 2% within 48 h respectively for mixed bacteria and 20. 0%-21. 6% within 48 h for any of the six sigle bacteria.更多还原
