“…cerevisiae for a sterol and an unsaturated fatty acid (Andreasen & Stier, 1953, 1954. Both of these nutritional requirements are fairly broad (Light et al, 1962;Proudlock et al, 1968) and this permits specific enrichments to be made in the sterol (Hossack & Rose, 1976) and fatty-acyl composition of plasma membranes (Thomas et al, 1978) without altering the content and composition of other types of lipid in organisms (Rose, 1977).…”

“…The change in lipid composition between aerobic and anaerobic yeasts has earlier been reported (Kovâc et al, 1967;Jollow et al, 1968;Castelli et al, 1969b;Hunter and Rose, 1972;Watson and Rose, 1980) and reviewed by Rattray et al (1975). Since anaerobic yeast cells can be supplemented with a variety of fatty acids, sterols, and their derivatives, the requirements for both UFA and sterols were initially thought to be fairly nonspecific (Light et ai, 1962;Meyer et ai, 1963;Proudlock et al, 1969;Hossack and Rose, 1976). This is because oxygen is essential for the synthesis of the two cellular constituents, viz.…”

“…The only limitation with such studies has been that environmentally induced alterations have led to gross lipid changes. The normal growth of anaerobic cells could ensue if the cells were supplemented with unsaturated fatty acids and ergosterol (Light et al, 1962;Proudlock et al, 1969). S. cerevisiae, if grown under strict anaerobic conditions, becomes auxotrophic for UFAs and ergosterol Stier, 1953, 1954).…”

“…For growth to occur, the medium must be supplemented with these components, and these are incorporated into the membranes of the growing cells. The lipid composition of cells and promitochondria then reflects the nature of the growth supplements used (Bloomfield & Bloch, 1960;Proudlock, Wheeldon, Jollow & Linnane, 1968;Gordon & Stewart, 1971). Within certain limits, variation of the degree of supplementation, as well as the type of lipid provided, results in a corresponding change in the chemical composition of the membranes.…”
