Paraburkholderia Xenovorans Strain LB400 Significantly Decreased Volatilization of Polychlorinated Biphenyls (PCBs) from Freshwater and Saline Sediments.

ABSTRACT: Airborne PCB emissions from contaminated sediments pose a public health risk and are frequently cited as a concern for communities located near PCB-contaminated bodies of water. We assessed the potential to decrease the emissions of lower-chlorinated (LC)-PCBs (<3 chlorines) through bioaugmentation with aerobic PCB-degrading Paraburkholderia xenovorans strain LB400 in laboratory microcosms using historically PCB-contaminated sediments from a wastewater lagoon (Altavista, VA; AVL) and an estuary (New Bedford Harbor, MA; NBH). We compared the impact of nonshaken vs shaken conditions on airborne PCBs in LB400-bioaugmented AVL sediment (51% LC-PCBs) to better replicate field conditions. After 35 days, airborne LC-PCBs decreased by 54% in nonshaken bioaugmented AVL sediments, compared to
