Biological nitrogen removal has been focused on in wastewater treatment field recently. A strain X7 was isolated from the sediment of pickle foodstuff wastewater. Based on its 16S rDNA sequence analysis, X7 was identified as Bacillus cereus. At NaCl concentration of 20 g/L, NH4+-N removal rate achieved 99.18%, when NO2--N and NO3--N removal rates were 77.24% and 68.6%, respectively. When NaCl concentration ranged from 0 to 40 g/L, the removal rate of NH4+-N was more than 97.59%. Therefore, due to the high nitrogen removal rate and excellent salt tolerance, Bacillus cereus X7 had a broad application prospect in the biodenitrification of brine wastewater.
