Abstract
Provided are an engineered strain for synthesizing a dibasic organic acid and preparation and application of same. The engineered strain introduces or up-regulates expression of a positive regulator gene for synthesis of a dibasic organic acid, and/or down-regulates expression of a negative regulator gene for synthesis of a dibasic organic acid, as compared with the origin strain of the engineered strain, the producing capability for producing the dibasic organic acid is improved. The dibasic organic acid comprises malic acid, succinic acid, fumaric acid, oxaloacetic acid, glutaric acid, and adipic acid; the expression product of the positive regulator gene comprises aspartate aminotransferase, glutamic acid-aspartate transporter, C4-dicarboxylic acid transporter, pyruvate carboxylase and malate dehydrogenase, glucose transporter; the expression product of the negative regulatory gene comprises succinyl-CoA synthase, and malic acid-alpha ketoglutarate transporter, and the original strain comprises, and
