Abstract
Enzyme synthesis of tryptophan from indole, pyruvate and ammonium salts was studied using Escherichia coli cells exhibiting a significant tryptophanase activity. In addition to the effect of cultivation medium composition and cultivation conditions, factors affecting the course of the conversion were investigated. Production of 32.4 g/L of L-tryptophan was reached after 48 h under optimal conditions.Entities:
