title: Lectin mediated agglutination of Candida kefyr cells and their spheroplasts grown in sterol enriched growth medium and its correlation with lipid composition.
abstract: Supplementation of the growth medium with erosterol, cholesterol and lanosterol enriched the Candida kefyr cells, presumably cell membranes with sterols. Sterol enriched C. kefyr cells showed a decrease in percentage of PHA and Con-A mediated agglutination. Sterol supplementation also increased the sterol: phospholipid ratio and in such cells unsaturated fatty acids predominated over saturated ones. The overall effect of these changes resulted in rigidifying the cell membranes as indicated by shift of break in Arrhenius plots of Mg2+ ATPase. This showed that lectin mediated agglutination of yeast cells may be affected by its membrane fluidity.
