title: [Effect of magnesium concentration in the culture medium on the trace element requirement of yeasts].
abstract: The effect of different magnesium concentrations in the culture liquid (ranging from 2=6 to 220 mg/l) on the accumulation of Mg and Mn ions in the yeast Candida guilliermondii was studied during their continuous cultivation on purified liquid paraffins. A reverse correlation between the accumulation of magnesium and manganese in the yeast biomass was established. The magnesium content in the biomass increased with an increase of its concentration in the nutrient medium. The biomass yield was optimal at a concentration of magnesium ions in the nutrient medium of 10=25 mg/l. Under these conditions the content of magnesium ions was 0.4 mg % and that of manganese ions (upon their concentration in the nutrient medium of 1=2 mg/l) was 20 mg%.
