Abstract

PURPOSE: To prepare the titled substance in high yield, by cultivating a variant strain which belongs to the genus Bacillus, Brevibacterium, Corynebacterium, Arthrobacter, etc. and has the resistance to indolmycin, etc.
CONSTITUTION: A variant strain, which belongs to the genus Bacillus, Brevibacterium, Corynebacterium, Arthrobacter, Microbacterium or Escherichia, and has the resistance to at least indolmycin or N-demethyl-C-demethyl-indolmycin, e.g. Bacillus subtilis AJ11488, Brevibacterium flavum AJ11490 or Corynebacterium glutamicum AJ11492, is cultivated in an ordinary liquid culture medium aerobically. L-Trypthophan in then isolated from the culture by the ion exchange resin method, etc.
