PURPOSE:To prepare L-phenylalanine in high yield, by cultivating a bacterium belonging to the genus Brevibacterium or Corynebacterium having resistance to glutamine analogs. CONSTITUTION:A bacterium such as Brevibacterium lactofermentum AJ11821 (FERM-P6442), Corynebacterium acetoacidophilum AJ11823 (FERM-P6444), etc. belonging to the genus Brevibacterium or Corynebacterium, obtained by variation treatment from a bacterium capable of producing L-phenylalanine, having resistance to glutamine analogs is cultivated in a nutritive medium under aerobic conditions, and L-phenylalanine is collected from the culture solution. |
