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.

本研究采用亚硝化细菌富集培养基选择培养和硅胶平板分离法，从本校农场菜园土中分离到31株细菌，以格利斯试剂对培养液的反应颜色深浅作为指标衡量其产NO_2~-的多少，经初筛从分离株中筛选出13株格利斯试剂反应颜色较深的菌株，再对这13株菌作亚硝化试验，最终选出一株亚硝化速率较高的菌株(编号为N_4，下同)；另外，通过对本实验室保存的反硝化细菌混合菌液进行分离复壮，筛选出一株反硝化速率高的菌株编号为B_
