The adsorption of phenols and esters of acid antiseptics by the bacterial cell (Escherichia coli and Staphylococcus aureus) was investigated in relatoin to their toxic effect, and it has been observed that the definite quantity of antiseptics must be adsorbed on the solid phase of the bacterial cell in order to give the definite toxic effect, and the toxic effect is independent of the quantity dissolved in the inner cell fluid or in the lipid phase of the cell. The result shows that the toxic effect of these antiseptics on either bacteria and yeast, is exclusively limited by the adsorbed quantity.
The adsorbed quantity required for the definite toxic effect was nearly the same as that previously observed in the case of the yeast, and the mechanism of the toxic action of these antiseptics was assumed to be same with each other in any case of microbes.
