Abstract
A process for producing L-tryptophan in which a suitable substrate such as a carbohydrate, indole or anthranilic acid is contacted with Coryneform bacteria, where the Coryneform bacteria bear recombinant DNA constructed by connecting a gene coding for tryptophan synthetase with a plasmid vector capable of proliferating in Coryneform bacteria.
