Figure 2. The S. flexnerioxyR mutants show reduced viability in LB under aerobic growth conditions.

Figure 2

Overnight cultures of the each strain were diluted to an OD650 of 0.015 in LB and grown at 37°C under aerobic conditions for 8 hours. Serial dilutions of each culture were spotted on Congo Red plates containing 40 units of catalase per plate to determine viable bacterial colony forming units (CFU) per ml. The data presented are the means of three experiments, and the standard deviations of the means are indicated. The difference between SM100 and UR021 and between SM100 and UR025 was significant (p<0.05).
