Název v původním jazyce

Sediment-free anaerobic microbial enrichments with novel dechlorinating activity against highly chlorinated commercial PCBs

Popis výsledku v původním jazyce

Reductive dehalogenation by anaerobic bacteria is a promising method of detoxifying polychlorinated biphenyls (PCBs) in aquatic sediments. PCB-contaminated sediment from Strazsky Sewer river (Slovakia) was used as an inoculum to develop stable sediment-free enrichments with dechlorination activity directed against the commercial PCB mixture Aroclor 1260. RESULTS: Characterization of the PCBs at the site revealed that 45 mol% of the PCBs were dichlorobiphenyls and 62% of the chlorines were in the ortho-position. Both findings are characteristic of extensive dechlorination in situ. Sediment-free enrichments with stable dechlorinating activity against Aroclor 1260 were developed by a series of transfers. These enrichments targeted hexa- through nonachlorobiphenyls and dechlorinated them to tri- through hexachlorobiphenyls by removal of flanked meta- and para- chlorines when pyruvate or lactate was added as a carbon source. The known haloprimers: 4,4'-dibromobiphenyl and 2,6-dibromobipheny
