The present invention relates to a microorganism having L-tryptophan production ability and a method for producing L-tryptophan using the same. More specifically, the present invention provides tryptophan obtained by genetic engineering through release of chromosomal tryptophan requirement from E. coli mutant strain (KFCC 10066) having L-phenylalanine production capacity, blocking L-phenylalanine biosynthesis and enhancing tryptophan biosynthesis related genes. It relates to a recombinant E. coli strain CJ600 (KCCM 10812P) having a production capacity and a method for producing L-tryptophan using the same.n n n Escherichia coli, L-tryptophan, tryptophan depletion, pheA, trpR, mtr, tnaAB, aroG, trpE, mutation |
