Figure 3

Production of gaseous nitrogen by P. stutzeri UFV5 bacteria during the ammonium removal under aerobic conditions. The positive control of the technique was performed by the injection of pure atmospheric air, the positive control of the biological process was HNM medium inoculated with nitrifying activated sludge, and negative control was HNM medium without inoculum. Axis X = time, in minutes, of gas detection, and axis Y = signal intensity, the larger the peak, the greater the amount of gaseous nitrogen produced.
