    摘要:

    利用BTB培养基从实验室驯化成熟的SBR反应器的活性污泥中筛选出一株高效异养硝化-好氧反硝化菌株WYLW-X06. 通过对菌株WYLW-X06的形态观察、生理生化特征测定、Biolog鉴定,以及16S rDNA序列测定,认定菌株WYLW-X06是蜡状芽孢杆菌(Bacillus cereus) . 对菌株脱氮性能的研究结果表明:该菌株脱氮效果良好,氨氮去除率达到97.18%,总氮去除率96.63%, N2O气体总产量1.848987mg, N2O-N产量占总氮去除量的0.572%.

    Abstract:

    By using BTB medium, a heterotrophic nitrification-aerobic denitrifier was isolated from the laboratory SBR reactor fast and efficiently. The strain, coded as WYLW-X06. It was identified as Bacillus cereus according to the analysis of its morphological and physiological features and Biolog system analysis as well as 16S rDNA sequences. The results show that ammonia nitrogen loss through heterotrophic nitrification in the liquid culture medium inoculated with WYLW-X06 reached 97.18% and the removal rate of TN was 96.63%, N2O production was 1.848987mg, the production of N2O-N accounted for 0.572% of the removal TIN.
