Abstract
A process for preparing alanine by culturing a genetically modified microorganism that produces alanine from glucose. The microorganism is one that has been modified to result in an overexpression of an endogenous alanine dehydrogenase gene, expression of a heterologous alanine dehydrogenase gene, or a combination of both. The source of alanine dehydrogenase may be The modified microorganisms may be a homofermentative microorganism, such as a strain of . The process can be used for in situ and stereoscopic preparation of alanine. The invention also relates to the microorganisms and the recombinant DNA molecules that can be used in the invention, as well as to alanine and alanine-containing products obtained according to the process of the invention.
