BACTERIUM BELONGING TO THE GENUS ESCHERICHIA BEING TRANSFORMED BY THE GENE ENCODING PYRUVATE CARBOXYLASE AND WHICH PRODUCES L-AMINOACID, AND FERMENTATIVE METHOD FOR PRODUCING L-AMINOACID

摘要

L-amino acid such as L-threonine and L-glutamic acid is produced by cultivating a bacterium belonging to the genus Escherichia which is transformed with a gene coding for pyruvate carboxylase and has L-amino acid productivity, producing and accumulating L-amino acid in the medium and collecting the L-amino acid from the medium.
