Profiling the Dcnitfiding Charactcdstics of three Dcnitrogcnation Bactcda Strains
Abstract：The nitrogen elimination effects of strains F4, F6 and F7 were investigated. Furthermore, nitrogen removal ability of three strains bacteria were evaluated in the treatment of actual aquaculture wastewater. The experiment results showed that strains F4, F6 and F7 grew and showed nitrogen removal ability in the medium when seignette salt, sodium acetate, sodium succinate or sodium citrate was provided as the sole carbon source respectively, and seignette salt was the most effective one. As the C/N rate was less than 12, the removal rate of the nitrogen increased rapidly with the increased of the C/N rate in cultural medium. More over, the results showed that the best pH was the weak alkaline(pH 8~9) and the best temperaatre for three strains bacteria was ranged from 25 ~C to 30 ~C. Besides, the pH value rose in the whole nitrogen removal process. Nitrogen removal capability of strains F4, F6 and F7 were relatively strong and they could exhibit broad application prospects in aquaculture wastewater treatment.
