Figure 4. Nutrient starvation model of nonreplicating persisters.
The viability of mid-log phase (black bars) or nutrient-starved (gray bars) after exposure to DMSO carrier (1% v/v), 1 µg/mL of isoniazid (INH), or 1 µg/mL of 9a. Averaged results and SEM from two biologically independent experiments are presented.
