Biodegradation of phenol and chlorophenol mixture by magnetic immobilized cells of Rhodococcus rhodochrous DSM6263. k-Carrageenan and 9 g/L Fe3O4 NPs were used as the immobilization support. The mixture contained phenol, 2-chlorophenol, 4-chlorophenol and 2,3-dichlorophenol. Each compound was added at the initial concentration of 0.25 mM, respectively. The error bars in the figure indicate the standard deviation of three parallel replicates
