“…The surrounding broth was completely clear and devoid of cells and fatty acid. Considering the problems that we encountered in estimating the cell population in broths containing low concentrations of fatty acids by means of optical density measurements and colony counts, it is difficult to understand how others (1,9) have applied these methods to broth cultures containing considerably higher concentrations of fatty acids without any difficulties that were worthy of mention.…”

The effect of supplementing nutrient substrate with various combinations of concentrations of oleic and linoleic acids on the growth of 11 strains of Staphylococcus aureus was assessed. Whereas increasing the concentration of linoleic acid by itself greatly diminished the growth of all 11 strains, concomitant increases in oleic acid greatly diminished the inhibitory effect of linoleic acid. With oleic acid in the nutrient substrate, most of the strains were induced to produce slime which surrounded the cells. Since the slime incorporated oleic but not linoleic acid, such slime production isolated the cells from direct contact with the growth inhibitor, linoleic acid.
