Abstract

The invention relates to a process for the fermentative preparation of L-threonine in which an L-threonine-producing microorganism of the Enterobacteriaceae family is cultured by the feed process, and a portion of the fermentation broth is then separated off in order to be utilized for inoculation of further media.
