FIELD: biotechnology.
SUBSTANCE: group of inventions relates to biotechnology. Disclosed is a bacterium of the type Escherichia coli, having the ability to produce L-threonine, characterized by that in it the gene yifK is inactivated. Disclosed is a method for microbiological synthesis of L-threonine using said bacteria. Disclosed is Escherichia coli strain VKPM V-13240 – a threonine producer.
EFFECT: group of inventions widens the range of Escherichia coli-type bacteria capable of producing L-threonine, and an arsenal of methods for microbiological synthesis of L-threonine, and also increases production of L-threonine in said modified microorganism as compared to a control parental microorganism.
