概要
- 論文の詳細を見る
Washed cells of a newly-developed double auxotroph for lipoic acid and thiamine, Enterobacter aerogenes LT-94,produced about 30 g/l of pyruvic acid from 5% glucose, and subsequently converted the acid to tryptophan in a yield of 16.7 g/l by the reverse reaction of tryptophanase, which had been induced under derepressed conditions. These yields were higher than those of the parent strain, L-12,showing only lipoic acid auxotrophy.
