Abstract:
ve To control and minimize the water pollution by nitrogen. Methods The autotrophic amino-oxidizing bacteria in soil were screened by enrichment and incubation. After bacterio-morphological identifica-tion their nitrifying rates were determined. Results All of the 12 screened strains were gram-negative and in the shape of brevi-rod dorminantly. The colonies with a dorminant form of short diameter in round shape, light yellow and smooth formed after 7-day incubation at 28℃ . The nitrifring rates ranged 0.40 mg/ (L?d)~1. 15 mg/ (L?d) . Conclusion The screened 12 strains all presented nitrifying function, some of them could be used to control water environment pollution by nitrogen.
