title: Oxygen and nitrate reduction kinetics of a nonflocculating strain of Zoogloea ramigera.
abstract: The oxygen and nitrate reduction kinetics of a nonflocculating strain of Zoogloea ramigera were determined. Axenic, nitrate-reducing bacterial suspensions were acclimated to various oxygen levels in a chemostat while measuring nitrate reduction in the presence of high ammonium nitrogen concentrations. Significant nitrate reduction was observed at oxygen concentrations up to 8 mg L-1. Oxygen consumption was inhibited by oxygen concentrations in excess of 2 mg L-1.
