Plasmid with wide host range and process of producing L. threonine using the same

摘要

This invention provides a plasmid with a wide host range, which can replicate in microorganisms belonging to the family Enterobacteriaceae. These plasmids may be used to clone the genes repsonsible for the fermentative production of various useful biochemicals. The recombinant plasmids containing these genes can be used to transform bacteria so that the fermentative production of the biochemical is enhanced.
