摘要： The method of acclimating aerobic denitrifying bacteria is studied from activated sludge by MBR system on treatment of aquaculture waste water. After 60 day, one strain aerobic denitrifying bacteria (named F28 strain), is isolated from the activated sludge. It was identified as pseudomonas sp based on its biochemical/morphological characteristics and physiological analysis of its 16SrRNA sequence. The denitrifying capability of the strain is studied in batch culture under aerobic condition. The results showed that the nitrate in the culture could be efficiently removed by F28 strain. Denitrification process of F28 strain mainly occurred in the exponential phase, and the nitrogen removal rate was up to above 70% in 24 hours. Nitrogen is obviously removed by the strain F28 strain on the aquaculture waste water.F28 strain is significant for the practical engineering.
