Molar fraction (%) of 4-chlorobiphenyl (CB), 2′-hydroxy- (OH-), 3′-OH-, 4′-OH-4-CB, and the metabolite, 4-chlorobenzoate (4-CBA), recorded in cell suspensions of B. xenovorans LB400 growing on succinate (1,180 mg L⁻¹, 10 mM) and biphenyl (770 mg L⁻¹, 5 mM). Results are presented as mean and standard deviation of three replicates

^a100% corresponded to 10 mg L⁻¹ of 4-CB, 2′-OH-, 3′-OH-, and 4′-OH-4-CB.

^b100% corresponded to 2 mg L⁻¹ of 4-CB, 2′-OH-, 3′-OH-, and 4′-OH-4-CB.
