Growth of C48–1, △aspA::kan, C△aspA::kan and △aspA::kan (pAL99S) in complex media under aerobic conditions. The growth curves were measured in (a) TSB, (b) LB and (c) MH. Growth of C48–1 and △aspA::kan in LB (d) and MH (e) supplemented with fumarate. The growth curves of C48–1 and △aspA::kan were determined after incubation in LB and MH with or without 20 mM fumarate at 37 °Cfor 18 h. Data analyzed by Student’s t-test. * P < 0.05; ** P < 0.01 and NS (non-significant) for P>0.05
