    • The invention relates to a method for producing L-amino acids in which the following steps are carried out: a) the recombinant coryneform bacteria which produce the desired L-amino acid and in which at least one or several of the heterologous polynucleotides of the glycerol metabolism, selected among the group comprising glpA, glpB, glpC, glpD, glpE, glpF, glpG, glpK, glpQ, glpT, glpX, gldA, dhaK, dhaL, dhaM, dhaR, fsa, and talC, is/are expressed are cultivated in a medium containing glycerol or one or several other optional C sources in conditions in which the desired L-amino acid is enriched in the medium or the cells; and, optionally, b) the desired L-amino acid is isolated, all or fractions (> 0 to 100 percent) of the components of the fermentation broth and/or biomass optionally remaining in the final product. In said method, bacteria are used in which other genes of the biosynthesis pathway of the desired L-amino acid are additionally reinforced or in which the metabolism pathways reducing the formation of the desired L-amino acid are eliminated at least in part.
    • 本发明涉及一种用于生产L- L-氨基酸,该方法包括进行下列步骤:a)所需的L-氨基酸生产重组棒状细菌的培养中,至少一个或多个所述甘油的异源多核苷酸STOF fwechsels的( 甘油代谢)选自glpA,glpB,glpC,glpD,glpE,glpF中,glpG,GLPK,glpQ,glpT,glpX,GLDA,DHAK,木豆,DHAM,达尔,FSA和滑石选择,来表示() 在甘油或任选地加入一种或条件下含有培养基更多额外的C源,其中在培养基中或在细胞中的所需L-氨基酸富集,和任选地b)分离所需的L-氨基酸,其中所述发酵液的任选成分 和/或(> 0至100%)以其整体或在最终产物水平保持生物质。 并且其中除了所需的L-氨基酸的生物合成途径进一步扩增基因的细菌,或者其中代谢途径至少部分地消除,这减少所需的L-氨基酸的形成,被使用。
