摘要：

Alcaligenes faecalis strain WT14 is heterotrophic nitrification and aerobic denitrification bacterium, newly isolated from a constructed wetland, and its feasibility in nitrogen removal was investigated. The result showed sodium citrate was more readily utilized by WT14 as a carbon source. The response surface methodology model revealed the highest total nitrogen removal by WT14 occurred at 20.3 °C, 113.5 r·min−1, C/N 10.8, and pH 8.4. Under adapted environmental conditions, up to 55.9 mg·L−1·h−1 of ammonium nitrogen (NH4+-N) was removed...
