    摘要: A method of producing L-amino acids by fermentation. Microorganisms of the genus Corynebacterium which exhibit an auxotrophy relative to an amino acid are used as biocatalysts. The method is characterized in that the carbon source on the one hand and the limiting amino acid on the other hand are fed in two or more different infeed currents to the process. The infeed profiles have, for example, a concave (saccharose) and an exponential (amino acid) form or a convex (saccharose) and likewise a convex (amino acid) form, with specific differing degrees of increase of the currents relative to each other over time.
