Studies on Yeast Differentiation Using Organic Acid Metabolites Part 3. Studies on the Metabolites Produced by Yeasts Grown on a Selection of Single Carbon Substrates

Abstract

A study of the organic metabolites produced by four selected strains of yeast when grown on single carbon substrates is described. The products were chromatographed on Aminex HPX-87H resin as described previously (Part 1). Examples are given for glycerol, raffinose, cr-methyl glucoside, ethanol, lactate and succinate to illustrate how the methodology can be used to differentiate yeast strains.Some of the results obtained are in conflict with generally accepted classification.
