In this paper, adopted augmenting culture in nitrite bacteria culture media and the method of silica gel plate isolation,31 strains of bacteria were isolated from vegetable garden soil of our school. The color reaction test was carried out with Griess reagent and culture fluid, which was regarded as the index to determine producing NO2- or not. 13 strains which color were deep were obtained and they were further rescreened by doing nitrite test. A strain N4(coded N4,the same to the following)with higher rate of nitrosification was picked up after rescreened; A strain B08( coded B08 ,the same to the following) with higher rate of denitrification was obtained after isolated and rejuvenated from our lab conserving mixed denitrifying bacteria culture.
