FIELD: microbiological industry. SUBSTANCE: invention relates to new strains E. coli VKPM B-7386 and E. coli VKPM B-7388 producing L-leucine that are generated by selection of strains exhibiting the resistance to L-valine, 4-azaleucine, 3-hydroxyleucine and L-leucine on the basis of the strain E. coli K-12. EFFECT: high yield of L-leucine and resistance of new strains to L-leucine. 3 ex
