The fermentation ability of a strain of Kluyveromyes fragilis, already selected for rapid lactose-fermenting capability, was improved dramatically by the addition of unsaturated fatty acids and ergosterol to the medium. The fermentation time of a 20% whey-lactose medium was decreased from over 90 hours to less than 60 hours. The lipids were shown to be taken up by the organism, and the effects on specific growth rate and biomass production were determined. (Refs. 23).
