PROCESSO PARA PROVOCAR A SOBREPRODUCAO DE L-FENILALANINA EM MICROORGANISMOS E PARA A PRODUCAO DO GENE DE TRANSAMINASE TYR B

摘要

Isolation of the tyrB gene present in E. coli ATCC 11303 and cloning thereof in a multicopy plasmid results, after the transformation of the initial strain with this plasmid, in a 10-fold increase in the yield of L-phenylalanine.
