Abstract
A oligotrophic heterotrophic nitrifying bacterium Y21 was isolated from Songhua River at low temperature. The influence of temperature, pH, rotating speed of shaker as well as the carbon sources on the strain Y21 was investigated in this study. The experimental results showed that for the strain Y21, the optimum conditions were found to be temperature of 15 °C, pH of 7.4~8.2, shaking speed of 140 rmp respectively, with sodium acetate as carbon source. The strain Y21 has high activity under the culture condition at low temperature. The basic dynamic equation for the degradation of ammonia-nitrogen was obtained.
