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