The Influence of Culture Age on the Cellular Fatty Acid Composition of Four Selected Yeasts

Summary: Cellular fatty acids were extracted from cells of Debaryomyces vanrijiae, Saccharomycodes ludwigii, Endomyces fibuliger and Metchnikowia reukaufii at different growth stages of batch growth and analysed by gas chromatography. A high degree of variation in relative concentrations, as well as in composition, of fatty acids, was observed during the exponential and early stationary growth phases. Greater reproducibility and a relatively stable fatty acid composition were obtained with cells harvested in the late stationary phase.
