The ozonization treatment of bactericides was examined from its growth inhibition effect on Escherichia coli. No remarkable decrease of the inhibition rate was observed for 2-ethylimidazole, tributyltin fumarate, and 2-hydroxy-2-phenylmercurioxy-3, 5, 6 : 3, 5, 6-hexachlorodiphenylethane. The inhibition rate of imidazole increased by ozonization treatment. In the case of dichloroisocyanuric acid, the inhibition rate increased with an increase in ozone consumption after it decreased once. The inhibition rate decreased in proportion to the amount of ozone consumed in the case of sodium 2-mercaptobenzothiazole, sodium trichlorophenate, sodium tetrachlorophenate, and eight other bactericides.
