title: Combined effects of diphenyliodonium chloride, pine oils, and mustard oil soaps on certain microorganisms.
abstract: Bactericidal and bacteriostatic activities of an emulsion containing 10.0% (v/v) terpineol, 0.5% (w/v) diphenyliodonium chloride, 11.0% (v/v) ethyl alcohol, and 5.62% saponified mustard oil were tested against a number of different types of organisms. The bactericidal concentration for Salmonella typhosa was 1:400. In the presence of 5.0% horse serum, it increased to 1:250. The bacteriostatic concentration varied from organism to organism; Escherichia coli and Staphylococcus aureus required 4,000 mug/ml for complete bacteriostasis, whereas Corynebacterium diphtheriae, Salmonella paratyphi-A, and Shigella required only 2,000 mug/ml for complete inhibition. A 4.0% concentration of the emulsion killed the spores of Bacillus subtilis within 6 hr.
