The nitritation-anammox process, which involves partial aerobic oxidation of the ammonium to nitrite and following oxidation of ammonium by nitrite to molecular nitrogen, is an efficient and cost-effective approach for biological nitrogen removal from wastewater. To characterize the microbial communities involved in the nitrogen and carbon cycles in wastewater treatment bioreactors employing this process, we sequenced the metagenome of a sludge sample collected from the lab-scale nitritation-anammox sequencing-batch reactor. At the phylum level, Proteobacteria and Chloroflexi were the most numerous groups. Anammox bacteria belonged to the genus Brocadia. The obtained data will help to investigate the taxonomical and functional diversity the microbial communities involved in nitritation-anammox process, and will be used for genome-based analysis of uncultured bacterial lineages. The raw sequencing data is available from the NCBI Sequence Read Archive (SRR9831403) database under the BioProject PRJN0A55627.
亚硝化-厌氧氨氧化工艺涉及将铵部分好氧氧化为亚硝酸盐，随后亚硝酸盐将铵氧化为分子氮，是一种从废水中生物脱氮的高效且经济有效的方法。为了表征采用该工艺的废水处理生物反应器中参与氮和碳循环的微生物群落，我们对从实验室规模的亚硝化-厌氧氨氧化序批式反应器收集的污泥样品的宏基因组进行了测序。在门水平上，变形菌门和绿弯菌门是数量最多的类群。厌氧氨氧化菌属于布罗卡德氏菌属。所获得的数据将有助于研究参与亚硝化-厌氧氨氧化工艺的微生物群落的分类和功能多样性，并将用于对未培养细菌谱系进行基于基因组的分析。原始测序数据可从NCBI序列读取存档（SRR9831403）数据库获取，生物项目编号为PRJN0A55627。
