Proof of principle for biotechnological indole production in C. glutamicum C1*. Schematic view of TNA reaction for indole production (A). Production of indole upon expression of E. coli tnaA and Trp importer genes tnaB and aroP (B). Strains were grown in minimal medium CGXII supplemented with 40 g L⁻¹ glucose and 1 g L⁻¹ Trp . EV: empty vector pGold; EcTNA: TNA derived from E. coli; EcTnaB: Trp permease from E. coli; CgAroP: aromatic amino acid permease from C. glutamicum
