CEPA DE E.COLI RECOMBINANTE CJ600 QUE POSSUI PRODUTIVIDADE DE L-TRIPTOFANO E PROCESSOS PARA A PRODUÇÃO DA REFERIDA CEPA E PARA A PRODUÇÃO DE L-TRIPTOFANO

摘要

The present invention relates to a microorganism having L-tryptophan productivity and a method for producing L-tryptophan using the same. More precisely, the present invention relates to the recombinant E , coli strain CJ600 (KCCM 10812P) having tryptophan productivity produced from the mutant form (KFCC 10066) of E . coli having L-phenylalanine productivity, wherein tryptophan auxotrophy is released, L-phenylalanine biosynthesis is blocked but tryptophan productivity is enhanced by reinforcing the gene involved in tryptophan biosynthesis, and a method of producing L-tryptophan using the same.
