Isolation and characterization of an aerobic denitrifier

An aerobic denitrifying bacterial strain F6 was isolated from soil. The denitrifying experiment results showed that under aerobic conditions the reduction efficiency within 30 hours was up to 64.40% respectively with initial NO2-N concentration of 250 mg/L. On the basis of its physiological and molecular properties, strain F6 was identified as Paracoccus alcaliphilus.
