Polybrominated diphenyl ethers (PBDEs) are persistent organic pollutants prevalent in the environment. Organohalide-respiring bacteria (OHRB) can attenuate PBDEs via reductive debromination, but often producing toxic end-products. Debromination of to ether remains a rare phenomenon and is so far specifically associated with Dehalococcoides isolated from e-waste polluted sites. The occurrence PBDE debromination other ecosystems underpinning OHRB underexplored. Here we found that common trait sewage sludge microbiota, was produced as end-product at varying quantities (0.6-52.9% mol parent PBDEs) 76 84 cultures established bioreactor sludge. Diverse pathways converting ether, including several new routes, were identified. Although contributed Dehalogenimonas, Dehalobacter, uncultivated Dehalococcoidia likely played more important roles than previously recognized. Multiple dehalogenase genes (including bdeA, pcbA4, pteA, tceA) also coexisted Collectively, these findings contribute enhancing our comprehension environmental fate PBDEs, expanding diversity microorganisms catalyzing developing consortia for bioremediation application.

Many polycyclic aromatic hydrocarbons (PAHs) in the environment resulting from crude oil spills and incomplete combustion of organic matter are highly toxic, mutagenic, or carcinogenic to microorganisms humans. Bioremediation PAHs using that encode biodegradative genes is a promising approach for environmental PAH cleanup. However, viability exogenous often limited due competition with native microbial community. Instead relying on survival one few species bacteria, genetic bioaugmentation harnesses conjugative plasmids spread functional microbes. In this study, two plasmid backbones differ copy number regulation, replication, mobilization were engineered contain dioxygenase gene (bphC) conjugated soil bacteria including Bacillus subtilis, Pseudomonas putida, Acinetobacter sp., as well synthetic community assembled these bacteria. Fitness effects transconjugants significantly impacted rates transfer biotransformation model (2,3-dihydroxybiphenyl). A synergistic effect was observed which communities bioaugmented bphC had higher degradation than grown monocultures. Finally, conjugation associated relative abundances communities, underscoring how fitness impacts can shape structure function.
