ABSTRACT:
L-phenylalanine is produced by fermentation by culturing in a culture medium an L-phenylalanine producing microorganism constructed by incorporating a hybrid plasmid in a recipient strain of the genus Escherichia and recovering the L-phenylalanine which accumulates in the culture medium, said hybrid plasmid containing a deoxyribonucleic acid fragment possessing genetic information related to L-phenylalanine production and obtained from a phenylalanine analogue resistant mutant of the genus Escherichia.
