Anaerobic growth of C48–1, △aspA::kan, C△aspA::kan and △aspA::kan (pAL99S). The final OD₆₀₀ values were determined after incubation in TSB under aerobic or anaerobic conditions with or without 20 mM fumarate at 37 °C for 16 h. Data analyzed by Student’s t-test. * P < 0.05; ** P < 0.01 and NS for P>0.05
