  • L-threonine-producing microbacteria and a method for the production of L-threonine
    Patent number: 6132999
    Abstract: The present invention provides a novel microbial strain and a method for effectively producing L-threonine. The novel strain can grow on a medium containing molasses, a much cheaper raw material than sucrose. The exemplary novel strain E. coli BKIIM B-5318 bears the plasmid pPRT614, which has threonine biosynthesis genes (thr A, B and C), the expression of which is regulated by a lambda-phage PR promoter and temperature-sensitive C1 repressor. The present microorganism is prototrophic with regard to isoleucine. The strain E. coli BKIIM B-5318 produces more than 70 g/l of L-threonine when cultured at 38-41.degree. C. for 32 hours in a medium containing molasses.
