the enhancement of divalent cation uptake in yeast provoked by the membrane atpase inhibitors trifluoperazine , miconazole , compound 48/80 , ethidium , dio-9 and calmidazolium should be ascribed to an increase in cation permeability of the yeast rather than to hyperpolarisation of the yeast cell membrane .
