Aeq[Y!c$m0【摘要】:筛选对高浓度NH3-N养殖废水具有高效硝化能力的菌株,研究其硝化性能。通过比较几种已报道的筛选方法和不同生境中异养硝化细菌筛选效果,确定了以乙酰胺为唯一碳源和氮源,从高氨氮生境中可以筛选到高效的异养硝化细菌;进一步通过富集培养分离,从沼气池出水口水中分离到一株异养硝化细菌,并根据部分长度的16S rDNA序列进行了系统发育分析。该菌株具有高效异养硝化功能,在初始氨氮浓度为104mg·L-1的异养氨化培养基中培养12h后,氨氮和总氮去除率分别达81.7%和53.7%,最终氨氮和总氮去除率可达90.1%和61.3%,且培养液中无明显的硝酸盐氮和亚硝酸盐氮累积。16S rDNA的序列分析鉴定,该菌株与Paracoccus denitrificans具有99%相似性,结合生理生化分析认定该菌株是一株脱氮副球菌,命名为Paracoccus denitrificans FJAT-14899。筛选出的菌株Paracoccus denitrificans FJAT-14899对氨氮具有高效的去除率,显示了良好的应用前景。水利论文Vqe'P a(r5{%F
