FIG. 4.

Effects of CORM-3 on E. coli and S. aureus cell viability. (A) E. coli cells were grown in MS medium either aerobically or anaerobically and treated with 400 μM CORM-3. S. aureus cells were grown aerobically or microaerobically in LB medium to which 500 or 400 μM CORM-3 was added, respectively. (B) Sensitivity tests were conducted by plating dilutions of cultures grown as described in Materials and Methods after exposure to CORM-3 (+) or no treatment (−) in the absence or in the presence of Hb. The concentrations of CORM-3 used were the same as those indicated in the legend to panel A.
