| Abstract: | Escherichia coli and Pseudomonas aeruginosa grown in the presence of certain harmful organic solvents become susceptible to these solvents during the cultivation. This
susceptibility is conspicuous in the stationary phase of growth. The organic solvent tolerance levels of these microorganisms
were maintained when the oxygen concentration was kept high. The tolerance levels were maintained also when these organisms
were grown with nitrate present under anaerobic respiratory conditions.
