Metabolic Synergy of Dehalococcoides Populations Leading to Greater Reductive Dechlorination of Polychlorinated Biphenyls

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(5), P. 2384 - 2392

Polychlorinated biphenyls (PCBs) are dioxin-like pollutants that cause persistent harm to life. Organohalide-respiring bacteria (OHRB) can detoxify PCBs via reductive dechlorination, but individual OHRB potent in dechlorinating only specific PCB congeners, restricting the extent of dechlorination. Moreover, low biomass frequently leads slow natural attenuation at contaminated sites. Here we constructed defined microbial consortia comprising various combinations PCB-dechlorinating Dehalococcoides strains (CG1, CG4, and CG5) successfully enhance Specifically, consisting CG1 CG4 removed 0.28–0.44 0.23–0.25 more chlorine per from Aroclor1260 Aroclor1254, respectively, compared strains, which was attributed emergence new dechlorination pathways consortia. Notably, different populations exhibited similar growth when cocultivated, temporal differences expression dehalogenase genes indicated their metabolic synergy. Bioaugmentation with or led greater wetland sediments, augmentation consortium resulted greatest These findings collectively suggest simultaneous application multiple catalyze complementary pathways, is an effective strategy accelerate

Interspecies Mobility of Organohalide Respiration Gene Clusters Enables Genetic Bioaugmentation

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: unknown

Published: Feb. 19, 2024

Anthropogenic organohalide pollutants pose a severe threat to public health and ecosystems. In situ bioremediation using respiring bacteria (OHRB) offers an environmentally friendly cost-efficient strategy for decontaminating organohalide-polluted sites. The genomic structures of many OHRB suggest that dehalogenation traits can be horizontally transferred among microbial populations, but their occurrence anaerobic has not yet been demonstrated experimentally. This study isolates characterizes novel tetrachloroethene (PCE)-dechlorinating Sulfurospirillum sp. strain SP, distinguishing itself by showcasing mechanism essential horizontal dissemination reductive capabilities within populations. Its genetic characterization identifies unique plasmid (pSULSP), harboring dehalogenase de novo corrinoid biosynthesis operons, functions critical respiration, flanked mobile elements. active mobility these elements was through analyses spontaneously emerging nondehalogenating variants SP. More importantly, bioaugmentation microcosms with pSULSP DNA triggered PCE dechlorination in taxonomically diverse bacterial Our results directly support the hypothesis exposure anthropogenic drive emergence dehalogenating populations via gene transfer demonstrate which remediation could achieved environments.

Published: March 16, 2024

Abstract Background Massive amounts of sewage sludge are generated during biological treatment and commonly subjected to anaerobic digestion, land application, landfill disposal. Concurrently, persistent organic pollutants (POPs) frequently found in disposal systems, posing significant risks both human health wildlife. Metabolically versatile microorganisms originating from inevitably introduced potentially affecting the fate POPs. However, there is currently a dearth comprehensive assessments regarding capability microbiota geographically disparate regions attenuate POPs underpinning microbiomes. Results Here we report global prevalence organohalide-respiring bacteria (OHRB) known for their capacity sludge, with an occurrence frequency ~50% investigated samples (605 1186). Subsequent laboratory tests revealed microbial reductive dechlorination polychlorinated biphenyls (PCBs), one most notorious categories POPs, 80 out 84 microcosms via various pathways. Most chlorines were removed para - meta -positions PCBs; nevertheless, ortho -dechlorination PCBs also occurred widely, although lower extents. Abundances several well-characterized OHRB genera ( Dehalococcoides , Dehalogenimonas Dehalobacter ) uncultivated Dehalococcoidia lineages increased incubation positively correlated PCB dechlorination, suggesting involvement dechlorinating PCBs. The previously identified dehalogenase (RDase) genes pcbA4 pcbA5 tended coexist microcosms, but low ratios these RDase abundance indicated existence undescribed RDases sludge. Microbial community analyses positive correlation between biodiversity activity was apparent threshold co-occurrence network complexity beyond which decreased. Conclusions Our findings that exhibited nearly ubiquitous indicate widespread nonnegligible impacts on systems. diverse suggests as alternative source obtain POP-attenuating consortia calls further exploration populations
