Bioreactors for air pollution control are expected to encounter fluctuating conditions or periods without
pollutant supply. In the present study, we compare the performance of a two phase partitioning bioreactor(TPPB) and an
ordinary bioreactor (OB) after being exposed to hexane starvation period. In OB, after 3 of days starvation period the
removal efficiency was reduced by 99%, and about 6 days were needed to recover the initial removal efficiency when
the hexane feeding resumed. In contrast, in the TPPB the hexane removal efficiency was not changed significantly and
recovered to its initial removal efficiency within 10 hours. The results of this study show that the TPPB system can
effectively sustain the biological treatment of waste gas during starvation periods of hydrophobic pollutants.
