Abstract
The present invention relates to a long-chain dibasic acid with low content of hydroxyl acid impurity and a production method thereof, in particular to a method for producing a long-chain dibasic acid with low content of hydroxyl acid impurity by fermenting a long-chain dibasic acid producing strain prepared by homologous recombination method. The present invention relates to a recombinant long-chain dibasic acid producing microorganism, having increased alcohol dehydrogenase activity and optionally decreased acyl-CoA oxidase activity. The present invention also relates to a method of producing a long-chain dibasic acid by the recombinant long-chain dibasic acid producing microorganism and use thereof.
