摘要:
A method is provided for overexpressing an amino acid in a microorganism comprising the step of altering the chromosomal DNA of host microorganisms or transforming the host microorganisms with at least one expression vector such that the resultant microorganism will overexpress certain operons and be inactive with respect to the other operons in the biosynthetic pathway of the amino acid, whereby overexpression of the amino acid will occur.
