概要
- 論文の詳細を見る
5-Fluorotryptophan (5FT), indolmycin (IM), 4-fluorotryptophan and 7-azatryptophan were found on screening to be tryptophan antagonists among various chemically synthesized and naturally occurring tryptophan analogues for the isolation of L-tryptophan (L-Trp) producing mutants of Bacillus subtilis K. From among 5FT resistant mutants, potent L-Trp producers were abtained using an improved isolation medium. Growth of the isolated 5FT-resistant L-Trp prducer, AJ 11709, was inhibited by IM. From among 5FT and IM resitant mutants, the best strain, AJ 11979, which produced 9.0g/liter of L-Trp from 13% glucose on 120hr cultivation, was selected.
