RESUMO
Razin, S. (University of Connecticut, Storrs), M. E. Tourtellotte, R. N. McElhaney, and J. D. Pollack. Influence of lipid components of Mycoplasma laidlawii membranes on osmotic fragility of cells. J. Bacteriol. 91:609–616. 1966.—Lipid composition of Mycoplasma laidlawii membranes could be significantly changed by variations in the growth medium. The effect of these changes on the osmotic fragility of the cells was studied. Cholesterol, incorporated into the membrane from the growth medium, had no significant effect on osmotic fragility. Carotenoids, synthesized by the cells from acetate, were likewise without effect. Unsaturated long-chain fatty acids increased markedly the resistance of M. laidlawii to osmotic lysis and promoted growth. The fatty acids of the growth medium were incorporated mainly into membrane phospholipids. The ratio between saturated and unsaturated fatty acids in membrane lipids depended on that of the growth medium.
