ABSTRACT



Three variants of citric acid (CA) biosynthesis on sugar beet molasses by the yeast Y. lipolytica were investigated: (I) single cultures of Suc– strains on inverted molasses, (II) single culture of Suc+ recombinant strains on non-inverted molasses, (III) mixed cultures of Suc– and Suc+ strains on non-inverted molasses.

Key words: citric acid, sugar beet molasses, Yarrowia lipolytica, mutant strains, invertase-positive transformants, mixed cultures.
