Latest Patents

Christoserdov holds a patent for "L-threonine-producing microbacteria and a method for the production of." This invention introduces a novel microbial strain capable of effectively producing L-threonine. The strain, identified as E. coli BKIIM B-5318, can grow on a medium containing molasses, which is a more cost-effective raw material compared to sucrose. The strain bears the plasmid pPRT614, which contains threonine biosynthesis genes (thr A, B, and C). The expression of these genes is regulated by a lambda-phage PR promoter and a temperature-sensitive C1 repressor. Notably, this microorganism is prototrophic concerning isoleucine and can produce over 70 g/l of L-threonine when cultured at temperatures between 38-41°C for 32 hours in a molasses medium.
