摘要：

采用批式实验探究了碳源、抗生素、重金属对好氧反硝化苯胺降解菌株同步脱氮降解苯胺特性的影响。结果表明：经生理生化反应和16S rDNA测序，鉴定为不动杆菌属（命名为Acinetobacter sp.H3）。在30℃、90 r/min振荡培养条件下，异养硝化率、TN去除率、苯胺降解率最大分别达57.98%、54.24%、100%。在35 μg/L抗生素和80 mg/L重金属胁迫下，苯胺仍能完全转化降解，好氧反硝化则受到了不同程度的抑制。

Abstract:

Batch experiments were conducted to investigate the effects of carbon source, antibiotics and heavy metals on the characteristics of the simultaneous aerobic denitrification and aniline degradation of an aerobic denitrifier. The results showed that it was identified as a member of the genus Acinetobacter (named Acinetobacter sp. H3) by physiological and biochemical reaction and its 16S rDNA gene sequence analysis. Under the shaking culture conditions of 30℃ and 90 r/min, the heterotrophic nitrification rate, TN removal rate and aniline degradation rate reached 57.98%, 54.24% and 100%, respectively. Under the stress of 35 μg/L antibiotics and 80 mg/L heavy metals, aniline could still be completely transformed and degraded, and aerobic denitrification was inhibited to varying degrees.

Key words: Acinetobacter sp. H3, aerobic denitrification, aniline degradation
