Screening and identification of two heterotrophic nitrifying bacteria and characterization of their capacity for nitrogen removal
|
Abstract:
Objective] Two heterotrophic nitrifying bacteria,P2 and P9 isolated from piggery wastewater,were studied for their capacity of nitrification and nitrogen removal.Methods] Physiological characteristics and phylogenetic analysis based on 16S rDNA sequences of strains P2 and P9 were analyzed.The ammonia removal characteristics of strains P2 and P9 were investigated.Furthermore,nitrogen removal ability of strains P2 and P9 individually or mixed were evaluated in the treatment of actual piggery wastewater.Res...
