<p>The invention relates to a process for fermentatively preparing L-amino acids, in particular L-threonine, in which the following steps are carried out: a) the microorganisms which produce the desired L-amino acid and in which the yodA ORF, for nucleotide sequences or alleles encoding its gene product, is/are potentiated, in particular overexpressed, are cultured in a medium under conditions under which the desired L-amino acid is enriched in the medium or in the cells, and b) the desired L-amino acid is isolated, with, where appropriate, constituents of the fermentation broth, and/or the biomass, in its entirety or in portions (>= 0 to 100%), remaining in the isolated product or being completely removed.</p> |
