PURPOSE:To obtain L-phenylalanine useful as a raw material for dipeptide sweetener from a medium inexpensively, by cultivating a specific variant belonging to the genus Brevibacterium or Corynebacterium. CONSTITUTION:A variant such as Brevibacterium lactofermentum [AJ3450 FERM-P1912 (Tyr<->)], Brevibacterium lactofermentum [AJ3437 FERM P-1914 (Tyr<->, 5-MT<r>, p-F-Phe<r>)], Corynebacterium acetoacidiphilum [AJ3244 ATCC21421 (p-F-Phe<r>)] belonging to the genus Brevibacterium or Corynebacterium, demanding L-arginine in growth, capable of producing L-phenylalanine, is cultivated to form and accumulate L-phenylalanine, which is collected. |
