Fig 4. Effect of CORM-2 exposure on viability in E. coli K12 strain MG1655.

Fig 4

MG1655 was grown to early log phase in MS-medium and then exposed to A) CORM-2 (500 μM) for 1, 2 or 24 h or to B) CORM-2 (250 μM) for 1, 2, 4, 8 or 24 h. C) Bacteria with a recovered growth after 24 h of exposure to 250 μM CORM-2 (see panel B) were re-exposed to a higher concentration of CORM-2 (500 μM) and the viability evaluated. Data show viability after first-time exposure and after pre-exposure 10 or 20 times to CORM-2 (250 μM) or vehicle (2.5% DMSO). Viability is presented as log CFU/ml of CORM-2 exposed bacteria compared with the initial starting inoculum. The data are shown as mean ± SEM from three independent experiments.
