The effects on the A. niger fermentation of sucrose and molasses exerted by various concentrations of ethanol, acetate and pyruvate are examined in presence of the optimum concentrations of ferrocyanide and phosphate. Such mixtures gave appreciable increases in the yields of citric acid with also traces of oxalic acid and the time of incubation could be reduced. The behaviour of two potent citric‐acid‐producing strains of A. niger on molasses medium supplemented with methanol was also studied. The results are discussed in the light of well‐known metabolic pathways.
