Cobalt activation of fatty-acid synthesis in yeast homogenates.

The incorporation of acetate into lipids in homogenates of Saccharomyces cerevisiae was inhibited at low concentrations of ethylenediaminetetraacetate, under both aerobic and anaerobic conditions. Of various cations tested, none could effectively reverse this inhibition. However, Co(++) completely restored the synthesis of fatty acids, but not of nonsaponifiable lipids.
