Abstract:
A method for improving a strain of microorganisms capable of converting glycine to L-serine by selecting for strain-improving mutations such that the improved strain is serine dehydratase negative and is resistant to at least one of the amino acid analogs serine hydroxamate, glycine hydroxamate or methionine hydroxamate.
