Of the 62 kinds of compounds tested, 2, 4-dihydroxy-5-amylbenzaldehyde 4-p-tolyl-thiosemicarbazone and 2-cyclohexylphenol completely inhibited the growth of Staphylococcus aureus 209P in 1:80, 000 dilution, while 2-chloro-4-cyclohexylphenol and 2, 4-dihydroxy-5-chlorodiphenylethane arrested the growth of Bacillus subtilis completely in 1:80, 000 dilution. None of the compounds tested were effective in preventing the growth of Escherichia coli commuuior. Furacin used as the control was able to completely inhibit the growth of the three bacteria in 1:80, 000 dilution.
