Process for producing L-tryptophan, and a pure culture of a microorganism strain used in said process

In a process for producing L-tryptophan which comprises cultivating an L-tryptophan-producing mutant of Bacillus subtilis under aerobic conditions in a nutrient culture medium containing anthranilic acid, a carbon source, a nitrogen source and a mineral source, and recovering the resultant L-tryptop...

Zusammenfassung:	In a process for producing L-tryptophan which comprises cultivating an L-tryptophan-producing mutant of Bacillus subtilis under aerobic conditions in a nutrient culture medium containing anthranilic acid, a carbon source, a nitrogen source and a mineral source, and recovering the resultant L-tryptophan from the culture broth, the improvement wherein the mutant is a strain resistant to 5-fluorotryptophan and 8-azaguanine; and a pure culture of a microorganism strain used in said process.
