Isolation and Characterization of an Aerobic Denitrifier
一株好氧反硝化菌的分离及特性研究

An aerobic denitrifying bacterial strain CY1 was isolated from soil. The denitrifying experiment results showed that under anaerobic or aerobic conditions the reduction efficiency within 30 hours was up to 99.98% (anaerobic) and 60.16% (anaerobic) respectively with initial NO3-N concentration of 137.25 mg/L. According to its morphologica, physiological and biochemical characters, as well as 16S rDNA sequence homology comparison, strain CY1 was identified as a member of Paracoccus pantotrophus.
