PURPOSE:To obtain the titled compound useful as a raw material of sweetener, in high efficiency, by utilizing a microbial strain capable of producing L-aspartyl-L-phenylalanine by the condensation of L-aspartic acid and L-phenylalanine. CONSTITUTION:The objective L-aspartyl-L-phenylalanine (abbreviated as AP) useful as a raw material of a sweetener, L-aspartyl-L-phenylalanine methyl ester, can be prepared by condensing L-aspartic acid with L-phenylalanine in an aqueous medium by the action of a microbial strain belonging to Alcaligenes genus, Achromobacter genus, Corynebaterium genus, etc. and capable of condensing L-aspartic acid and L-phenylalanine to produce AP. |
