Biodegradation of chlorophenols by immobilized cells of Rhodococcus rhodochrous DSM6263 with different immobilization supports. a 2-chlorophenol, b 4-chlorophenol and c 2,3-dichlorophenol. The initial chlorophenol concentrations were 0.25 mM. The free active cells and inactive cells (autoclaved at 115 °C for 5 min) were used as positive and negative controls, respectively. The error bars in the figure indicate the standard deviation of three parallel replicates
