Abstract

PURPOSE: To collect the titled substance in a large a mount from a culture, by cultivating a variant strain of the genus Brevibacterium or Corynebacterium having a glutamic acid requirement and the ability to produce L-phenylalanine in a liquid culture medium.
CONSTITUTION: A variant strain, e.g. Brevibacterium lactofermentum AJ11554 or Corynebacterium acetoacidophilum AJ11557, which belongs to the genus Brevibacterium or Corynebacterium, requires glutamic acid for the growth thereof and has the ability to produce L-phenylalanine is cultivated in an ordinary liquid culture medium containing a carbon source, a nitrogen source, an inorganic salt, etc. at a pH of about 5W9 and about 20W40°C for about 1W4 days, and the L-phenylalanine is isolated by the conventional isolating method.
