(Left) Time course of the degradation of individual PCB congeners; (right) dendrogram of the PCB composition of the biofilms. Congeners are as follows: PCB 1, 2-chlorobiphenyl; PCB 3, 4-chlorobiphenyl; PCB 4, 2,2′-dichlorobiphenyl; PCB 5, 2,3-dichlorobiphenyl; PCB 6, 2,3′-dichlorobiphenyl; PCB 7, 2,4-dichlorobiphenyl; PCB 8, 2,4′-dichlorobiphenyl; PCB 9, 2,5-dichlorobiphenyl; PCB 13, 3,4′-dichlorobiphenyl; PCB 28, 2,4,4′-trichlorobiphenyl; PCB 31, 2,4′,5-trichlorobiphenyl; PCB 110, 2,3,3′,4′,6-pentachlorobiphenyl.
