Abstract

A process for the production of L-isoleucine using the microorganism, Escherichia coli H-8670 (FERM BP-4051) which has resistance to 0.2 g/l S-(2-aminoethyl)-L-cysteine or Escherichia coli H-8683 (FERM BP-4052) which has a resistance of 20 g/l of D-serine. The microorganism is cultured in a nutrient medium for a time and under conditions sufficient to produce L-isoleucine and the L-isoleucine is recovered from the medium.
