Liao et al. provided a timely bibliometric analysis of OHRB research over the past four decades, highlighting remarkable expansion this field and extensive collaboration among researchers (Liao al., 2024). Their study identified two primary foci, namely mechanistic exploration their interplay with environment. Looking ahead, they outlined several priorities for advancing research, including OHRB's role in biogeochemical cycles, enhancement capabilities through synthetic biology, investigation ecological interactions evolutionary pathways, as well potential other microorganisms (e.g., archaea) to perform dehalogenation.Lu explored critical roles cobamides, an essential co-factor reductive dehalogenases (RDases), microbial dehalogenation (Lu Specifically, review detailed structural diversity influence on activity, underlying catalytic mechanisms organohalide respiration. Additionally, it underscored importance interspecies between cobamides-producing OHRB. The cobamide producers supply cofactors that modify assemble into functional RDases, need consider these cobamides-producers when designing robust dehalogenating consortia.Electron transfer processes are fundamental dehalogenation.Eberwein discovered is feasible use cobalt-containing metal complexes (cobalt chelates) anode mediators replace halogenated compounds cultivation Dehalococcoides mccartyi CBDB1 bioelectrochemical systems (Eberwein cobalt chelates can putatively shuttle electrons respiration complex anode, coupling D. cells electrode via mediated extracellular electron transfer. This provides promising alternative traditional methods OHRB, eliminating its reliance toxic organohalides.Humic known ability mediate diverse processes, such reduction oxide nitrate (Yang 2021). Wang investigated how humin, humic acid, anthraquinone-2,6disulfonic acid affect dechlorination polychlorinated biphenyls (PCBs) (Wang showed solid-state enhanced meta-dechlorination PCBs, while others failed accelerate process.They proposed humin significantly PCB dechlorination, likely by facilitating improving bioavailability. These findings emphasize application substances improve bioremediation efficiency.Integrating materials offers exciting opportunities pollutant degradation. Niu reviewed biochar composites degrading chlorinated hydrocarbons (Niu discussed removal efficiency, influencing factors, reaction hydrocarbon Biochar itself adsorb chemical bonds surface, whereas composite able induce generation free radicals degrade hydrocarbons. Furthermore, coupled facilitates pollutants degradation establishing "electron bridge" biological non-biological components.Bioremediation at contaminated sites often challenged coexistence pollutants. Yang special issue underscores integrated approach dehalogenation, combining advanced insights material innovations. While synergistic effects hold great promise, complexity real-world environments necessitates continued intertwined dynamics tailored solutions. Future should focus scaling up applications, ensuring address pressing challenges environmental pollution contribute broader goal sustainable development. detoxification organohalides increasing concerns, per-and polyfluoroalkyl substances, remains understudied, requiring focused efforts. Theory-guided design consortia strategies also presents new avenue exploration, offering optimize efficiency expand applicability approaches.
