Abstract
The invention provides transgeniccells comprising a mutation in cydAB gene, and/or cyoABCD gene, and/or cbdAB gene, and/or ygiN gene, wherein the mutation reduces (preferably, but not necessarily, by 100%) the cytochrome oxydase activity of a protein encoded by cydAB gene, and/or cyoABCD gene, and/or cbdAB gene, and/or ygiN gene. In a preferred embodiment, the mutation is a deletion of the cydAB gene, cyoABCD gene, and cbdAB gene. In another embodiment, the mutation is a deletion of the cydAB gene, cyoABCD gene, cbdAB gene, and ygiN gene. In another embodiment, the transgeniccell, which comprises a deletion of cydAB gene, and/or cyoABCD gene, and/or cbdAB gene, and/or ygiN gene a) has substantially the same level of growth in oxic conditions as the level of growth in anoxic conditions ofthat lacks said deletion of cydAB gene, and/or cyoABCD gene, and/or cbdAB gene, and/or ygiN gene, and b) is capable of converting glucose to D-lactate and/or amino acid and/or 2,3-butanediol (2,3-BDO) under one or both of oxic conditions and anoxic conditions.
