Mutant Strain with improved Amino acid production by inactivating isocitrate lyase

摘要

The present invention relates to an arginine or glutamine production mutant strain comprising an inactivated isocitrate lyase and a method for producing the same. According to the present invention, it is possible to inactivate isocitrate lyase to produce a mutant strain having improved arginine or glutamine production ability and yield per unit without lowering the growth of an arginine or glutamine producing ability strain including wild type or activated isocitrate lyase, There is an effect that can produce glutamine. In addition, since the mutant strains of the present invention can be used to improve the yield and yield per unit of arginine or glutamine, there is an advantage of cost reduction when arginine or glutamine is used as a raw material.
