Biotransformation of 5-chloroindole to 5-chlorotryptophan using planktonic cells of four strains. Concentrations of 5-chlorotryptophan and 5-chloroindole were measured using HPLC and percentage 5-chlorotryptophan accumulation (a), percentage 5-chloroindole depletion (b) and the selectivity of the 5-chloroindole to 5-chlorotryptophan reaction (c) were plotted against time. All cells contained pSTB7.
