Abstract

This investigation is concerned primarily with the growth and virulence of pathogenic bacteria introduced into soluble oil emulsions. The soluble oils are petroleum or fatty oils emulsified with soaps of petroleum sulfonic acids, naphthenic acids, fatty acids, rosin, or tall oil. When mixed with water, the soluble oils form stable oil-in-water emulsions and, as such, are used in machine shops as coolants and lubricants in the cutting and grinding of metals. Unfortunately, they serve as excellent substrates for the growth of bacteria.
