中文摘要
翻译
我们通过批量转移的方法成功地浓缩了耐氨丙酸氧化菌。富集菌在5gNH4-N/L条件下能氧化丙酸。下一代测序表明，丙酸氧化菌的优势菌包括尖顶杆菌和隐气杆菌。此外，还观察到了产氢甲烷菌数量的增加，表明耐氨丙酸氧化细菌与产氢产甲烷菌之间存在着合养关系。
英文摘要
We have successfully enriched NH4-tolerant propionate-oxidizing bacteria by batch transfers. The enrichment culture can oxidize propionate under 5 gNH4-N/L. Next-generation sequencing showed the dominance of propionate-oxidizing bacteria, including Pelotomaculum and Cryptanaerobacter. In addition, the increase of hydrogenotrophic methanogens Methanoculleus was also observed, indicating the syntrophic relationship between NH4-tolerant propionate-oxidizing bacteria and hydrogenotrophic methanogens.
