| 摘 要： | 从胶州湾沉积物中分离出1株异养硝化-好氧反硝化菌株B307,采用16S rRNA基因序列分析对该菌株进行鉴定,采用单因素实验对其进行条件优化和耐盐特性研究,并在最优条件下考察其在单一和混合氮源中的脱氮效果.结果表明,该菌为Zobellella sp.,其最佳碳源为丁二酸钠,最适C/N为5,最适初始p H为9,最适温度为35~40℃.该菌株在混合氮源体系中12 h对NH_4~+-N和NO_3~--N的去除率分别为98.35%和99.75%;在盐度为75 g·L~(-1)(以NaCl计)条件下24 h对NH_4~+-N和NO_3~--N去除率仍分别保持在97.67%和94.39%.表明该菌株具有高效的异养硝化-好氧反硝化能力和较强的耐盐特性,在高盐废水脱氮等领域具有广泛的应用前景.
