ABSTRACT:
An L-valine-producing microorganism which is constructed by incorporation into a host strain of the genus Escherichia of a hybrid plasmid having inserted therein a DNA fragment with genetic information related to L-valine production which is derived from a donor strain of the genus Escherichia which is resistant to a valine analogue, is useful for the production of high levels of L-valine by fermentation.
