%X Method of isolating the heterotrophic nitrifiers and the characterization of the heterotrophic nitrification were studied.Two heterotrophic nitrifiers were newly isolated from a membrane bioreactor(MBR) in which the TN removal efficiency was 80.1%.The batch test results indicate that Bacillus sp.LY and Brevibacillus sp.LY could utilize the organic carbon as the source of assimilation when they grew on glucose and ammonium chloride medium companying the formation of oxidized-nitrogen.After 24 days incubation,the removal efficiencies of the COD by Bacillus sp.LY and Brevibacillus sp.LY were 71.7% and 52.6%,respectively.The removal efficiencies of ammonium nitrogen by the two isolates were 78.2% and 51.2% and the TN removal efficiencies by the two isolates were 61.2% and 35.6%,respectively.
