Pseudomonas sp. BCNU 106 isolated from industrial wastewater was able to produce indigo from indole by utilizing various organic solvents. BCNU 106 produced indigo effectively when grown in the presence of a large volume of p-xylene, propylbenzene, and mesitylene and a high level of indole. The present study demonstrated that the maximal yield was achieved with 20% (v/w) p-xylene and 4 g/l indole. Under these conditions, the indigo yield and the transformation efficiency of indole were 315.5 mg/l and 97%, respectively. The results suggest that Pseudomonas sp. BCNU 106 might be a potential candidate for industrially important indigo production.
