“…This is an evidence for unique and efficient dioxygenase system in this isolate and also bringing to focus the increasing concern about the toxicity of biphenyl to microorganisms (Rodrigues et al 2006). Although contrary to our observations, several workers have investigated the addition of biphenyl to significantly enhance the biodegradation of PCB commercial mixtures (Clark et al 1979;Baxter et al 1975;Brunner et al 1985;Bedard et al 1987;Kohler et al 1988;Mondello 1989;Seto et al 1995). Therefore, the degradation dynamics of SA-5 could have resulted from combined toxicity of Aroclor 1242 and biphenyl.…”

“…Although it has not been studied in mammalian systems, there is at least one report (45) that studies of individual chlorinated biphenyls do not accurately predict the rates of metabolism of the same compound in simple mixtures. Therefore, the overall problem of metabolic degradation of the commercial mixtures may be complicated by the possibility that certain PCBs are potent enzyme inducers but poor substrates and vice versa, with various degrees in between.…”

“…Yakın bir zamanda sedimentin olmadığı ortamda PCB'lerdeki klor bağlarını kıran mikroorganizmaların saf kültürlerinin üretilmesi için çalışmaların sürdüğü Cutter et al (1998) ve Wu et al (2000 tarafından belirtilmiştir (Robertson ve Hansen 2001). PCB'lerin Nocardia veya Pseudomonas türleri ile parçalanması Baxter et al (1975) tarafından çalışılmıştır. Deneysel koşullar altında düşük oranda klorlanmış olan bifenillerin birçoğu kolay şekilde parçalanırken yüksek oranda klor atomu ihtiva eden bazı bifenillerin ise eğer koşullar uygunsa parçalandıkları, bununla beraber saf izomer olarak 12 gün boyunca aynı bakteriye maruz kaldığında ise hemen hemen hiç etkilenmediği bulunmuştur.…”

“…PCB'lerin Nocardia veya Pseudomonas türleri ile parçalanması Baxter et al (1975) tarafından çalışılmıştır. Deneysel koşullar altında düşük oranda klorlanmış olan bifenillerin birçoğu (<= 3 klor atomu/molekül) kolay şekilde parçalanırken 6 tane klor atomu ihtiva eden bazı bifeniller ise eğer koşullar uygunsa parçalanabilmektedirler.…”
