Abstract
    In fluidized bed reactors, applied for nitrate removal in an aquaculture unit, denitrification of nitrate was found to result in an accumulation of nitrite. Isolation of denitrifying bacteria from these reactors revealed that most of these isolates produced nitrite from nitrate under controlled laboratory conditions. Two of the isolates, one which accumulated nitrite while respiring on nitrate, and the other not, were subject to further studies. It was found that nitrite accumulation in one of these isolates could be adequately explained by differences in the relative rates of nitrate and nitrite reduction. Inhibiting concentrations of nitrite were lower for the isolate which did not accumulate nitrite. Incubation of the nitrite-accumulating isolate with different carbon sources resulted in differences in the relative nitrite accumulation (as compared with the amount of nitrate reduced).
