摘要：A new strain, named SYF26, was isolated from the Hei He oligotrophic drinking-water reservoir in China. Based on its phenotypic and phylogenetic characteristics, the isolate was identified as a species of genus Acinetobacter. Strain SYF26 was able to grow at low NH4 +-N concentrations (5.46 mg l”1), and the nitrification rate was 0.064 mg NH4 +-N l”1 h”1. Low accumulation of nitrate and nitrite was observed throughout the ammonium removal experiment. Strain SYF26 reduced NO3 ”-N or NO2 ”-N. Nitrite reductase and periplasmic nitrate reductase were detectable. The putative nitrogen removal process carried out by the strain SYF26 is as follows: NH4 +ANH2OHANO2 ”ANO3 ”, then NO3 ”ANO2 ”AN2. Response surface methodology analysis demonstrated that the maximum removal of ammonium occurred under the following conditions: NH4 +-N concentration of 22.05 mg l”1, C/N ratio of 4.31, initial pH of 7.78 and temperature of 29.73 6C, where initial pH and temperature had the largest influence on ammonium removal.
