Abstract:	A nitrous oxide (N2O)-consuming bacterium isolated from farmland soil actively consumed N2O under high pH conditions. An acetylene inhibition assay did not show the denitrification of N-2 to N2O by this bacterium. When N2O was injected as the only nitrogen source, this bacterium did not assimilate NN2O. A polymerise chain reaction demonstrated that this bacterium did not have the typical nosZ gene. This bacterium belonged to Chitinophagaceae, but did not belong to known families that include bacteria with the atypical nosZ. This is the first study to show that a non-denitrifier actively reduces N2O, even under high pH conditions.
