The mechanisms of bactericidal action of hydrogen peroxide on E.coli were studied. It was found that incorporation of take up of
14C-glutamic acid,
3H-uracil, glucose, and galactose by E.coli was inhibited by H
2O
2 treatment and the inhibitory effect increased with the amount of hydrogen peroxide on cellular nitrogen. Membrane fragility of H
2O
2-treated cells of E.coli increased with increasing amount of H
2O
2 and this increase was assumed to be due to changes in the cell membrane. When the H
2O
2-injured cells (H
2O
2/N mg>50) were placed in bouillon and incubated at 37° with shaking, the injury and the growth rate were recovered gradually.
