Degradation activities of strain JAB1 towards PCB congeners. Biphenyl-induced JAB1 cells were co-incubated with commercial PCB mixture Delor 103 for 48 h, with individual congener depletion being determined by GC-MS. Degradation of the following biphenyl derivatives was monitored but not observed: 2,2′-diCl, 2,2′,3-triCl, 2,2′,5-triCl, 2,2′,4-triCl, 2,2′,4,6′-tetraCl, 2,2′,3,6-tetraCl, 2,2′,3,6′-tetraCl, 2,2′,5,5′-tetraCl, 2,2′,4,5′-tetraCl, 2,2′,4,5 tetraCl, 2,2′,4,4′-tetraCl, 2,2′,3,5′-tetraCl, 2,2′,3,4′-tetraCl, 2,3′,4′,6-tetraCl, 2,2′,3,4 tetraCl, 2,3,4′,6-tetraCl, 2,4,4′,5-tetraCl, 2,3′,4′,5-tetraCl, 2,3′,4′,5′-tetraCl, 2,3′,4,4′-tetraCl, 3,3′,4,4′-tetraCl, 2,2′,3,4′,6-pentaCl, 2,2′,3,4,6′-pentaCl, 2,2′,4,5,5′-pentaCl, 2,3,3′,5′,6-pentaCl, 2,2′,4,4′,5 pentaCl, 2,2′,3,4′,5′-pentaCl, 2,2′,3,4,5′-pentaCl, 2,3,3′5,5′-pentaCl, 2,3,3′,4′,6-pentaCl, 2,2′,3,3′,4-pentaCl, 2,3′,4,4′,5-pentaCl, 2,3,3′,4,4′-pentaCl
