説明
<jats:p>The uneven distribution of Mg2+, K+, and phosphate in Saccharomyces carlsbergensis was demonstrated by the differential extraction of ions. Their concentrations were 5, 60, and 1 mM in the cytoplasm and 73, 470, and 110 mM in vacuoles, respectively. The intracellular gradients of these ions were 1:15, 1:8, and 1:110, respectively, across the tonoplast. The determination of free Mg2+ (1.35 mM in the cytosol and 20 mM in vacuoles) showed that the ion accumulation in vacuoles could not be explained by the higher degree of ion complexing in these organelles.</jats:p>
