Improved Preparation of El (L)-tryptophan by Tryptophan Synthase Using Organic Solvents

摘要

In the present invention, the initial indole concentration in the enzyme reaction system is increased by appropriately mixing a water-miscible organic solvent which has a relatively low solubility in the water-immiscible organic solvent and indole and has a relatively low solubility to the indole but improves the stability of the enzyme Tryptophan to increase the production concentration of L-tryptophan as an end product.
