中文摘要
翻译
我们成功地通过批转移富集了耐nh4丙酸氧化菌。在5 gNH4-N/L条件下，富集培养可以氧化丙酸盐。下一代测序结果显示丙酸氧化菌占主导地位，包括Pelotomaculum和Cryptanaerobacter。此外，产氢甲烷菌的数量也有所增加，说明耐nh4丙酸氧化菌与产氢甲烷菌之间存在共生关系。
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.
