Membrane damage associated with inositol-less death in Saccharomyces cerevisiae.
The effect of inositol deficiency was studied on fermentation, respiration, and sugar and amino acid transport. It was found that the loss of fermetnation and respiration and sugar transport activity parallel the loss of cell viability. The loss of sugar transport activity is associated with the development of cell membrane damage. It is concluded that the ultimate cause of cell death is cell membrane leakiness.
