Abstract
The bactericidal efficiencies of phenol, orthocresol, paracresol, orthobutylphenol, parabutylphenol, resorcinol, ethyl alcohol, and n-butyl alcohol against Staphylococcus aureus and Eberthella typhosa were detd. by a modified Rideal-Walker technique. Parallel tests were made with each disinfectant and test organism at temps. 10[degree]C apart, and temp. coefficients were calculated by dividing the disinfection time in min. at the lower temp. by the disinfection time at the higher temp. By averaging results from several concs. in individual expts. and the results obtained in a considerable number of expts., it was possible to obtain average temp. coefficients of sufficient accuracy to permit their use in calculating disinfection time at one temp. from results obtained at another. The exptl. evidence presented indicates that the effect of temp. on bactericidal activity varies with each disinfectant and each test organism.
