Abstract
For mass production of lactic acid, we newly constructed a transgenic wine yeast strain that included six copies of the bovine l-lactate dehydrogenase gene on the genome. On fermentation in inexpensive cane juice-based medium, l-lactate production of this recombinant reached 122 g/liter and the optical purity was 99.9% or higher.Keywords
