From: The significance of proline and glutamate on butanol chaotropic stress in Bacillus subtilis 168

Butanol tolerance of B. subtilis 168. Cells were inoculated in LB medium and exposed to butanol at various concentrations (vol/vol). Cell growth was measured to evaluate butanol tolerance in comparison to that of a non-butanol exposed cell control. Data are means of the results from at least three individual experiments. Error bars indicate standard errors
