Expression of the cytosolic NoxE enzyme for consumption of excess NADH and downregulation of glycerol production. A Production of 2,3-BDO from glucose in the HGS8 strain expressing the NoxE gene from Lactococcus lactis encoding a water-forming NADH oxidase. B Production of 2,3-BDO from 10% glucose in the HGS15 strain with deletion of GPD1 and GPD2. C Production of 2,3-BDO from 19% glucose in the HGS15 strain with deletion of GPD1 and GPD2. D Production of 2,3-BDO from 19% glucose in the HGS17 strain with replacement of the GPD1 with the CYC1 promoter. E Production of 2,3-BDO from 19% glucose in the HGS28 strain with expression of GPD1 from the CYC1 promoter in the Mk20 site
