Fermentation results of thick juice worts. Different letters indicate significant differences (P <0.05) between the means of intake of sugars (lowercase letters) and ethanol yield (capital letters). Variants of fermentation: I, extract content of 250 g/kg, inoculum content of 1.0 g/L; (NH₄)₂HPO₄. II, extract content of 250 g/kg, inoculum content of 1.0 g/L; (NH₄)₂HPO₄ + MgSO₄ · 7 H₂O. III, extract content of 250 g/kg, inoculum content of 1.5 g/L; (NH₄)₂HPO₄. IV, extract content of 250 g/kg; inoculum content of 2.0 g/L; (NH₄)₂HPO₄. V, extract content of 280 g/kg, inoculum content of 1.0 g/L; (NH₄)₂HPO₄. VI, extract content of 280 g/kg, inoculum content of 1.0 g/L; (NH₄)₂HPO₄ + MgSO₄ · 7 H₂O. VII, extract content of 280 g/kg, inoculum content of 1.5 g/L; (NH₄)₂HPO₄. VIII, extract content of 280 g/kg, inoculum content of 2.0 g/L; (NH₄)₂HPO₄.
