Abstract excerpt
Saccharomyces cerevisiae baker's yeast mutants which produce 3 to 17 times as much lysine as the wild type, depending on the nitrogen source, have been selected. The baker's yeast strain was growth in a pH-regulated chemostat in minimal medium with proline as the nitrogen source, supplemented with increasing concentrations of the toxic analog of the lysine S-2-aminoethyl-L-cysteine (AEC). The lysine-overproducing...
