Distinctive denitrifying capabilities lead to differences in N2O production by denitrifying polyphosphate accumulating organisms and denitrifying glycogen accumulating organisms

[Display omitted] •Denitrification kinetics for a dPAO and a dGAO culture are studied separately.•N2O accumulation is higher in dGAOs than in dPAOs.•Nitrite inhibits the nitrous oxide reduction in dGAOs but not in dPAOs.•There is no electron competition in any of the cultures. This study aims at inv...
