Production of D-lactic acid with yeast

摘要

A yeast strain, wherein the yeast strain is transformed with at least one copy of a gene coding for D-lactate dehydrogenase functionally linked to a promoter sequence allowing the expression of the gene in the yeast strain and the yeast strain has undergone disruption of one or more pyruvate decarboxylase genes or pyruvate dehydrogenase genes. Also, a method of producing D-lactic acid including culturing such a yeast strain in a medium and recovering D-lactic acid.
