Abstract

o-Chlorobenzylchloride, a simple aromatic halogen compound, was found to inhibit the growth of Saccharomyces cerevisiae and to lower the contents of sterols and fatty acids. The growth inhibition was considerably alleviated by the presence of sterols such as ergosterol and cholesterol and of unsaturated fatty acids such as oleate and linolenate. Inspection of effect of the inhibitor on the electron transport system related to the biosyntheses of these compounds revealed that the cytochrome contents and some enzyme activities in the system of the inhibited cells were much lower than those of the control cells. The features of the inhibition were similar to those of inhibition for other organisms by the hypocholesterolemic compounds such as triparanol and benzmalecene.
