TI  - Synergistic Effect of Soil Organic Matter and Nanoscale Zero-Valent Iron on 
      Biodechlorination.

AB  - Nanoscale zero-valent iron (nZVI) provides a promising solution for 
      organochlorine (OC)-contaminated soil remediation. However, the interactions 
      among nZVI, soil organic matter (SOM), and indigenous dechlorinating bacteria are 
      intricate, which may result in unascertained effects on the reductive degradation 
      of OCs and merits specific investigation. Herein, we isolated an indigenous 
      dehalogenation bacterium (Burkholderia ambifaria strain L3) from a paddy soil and 
      further investigated the biodechlorination of pentachlorophenol (PCP) with 
      individual and a combination of SOM and nZVI. In comparison with 
      individual-strain L3 treatment, the cotreatment with nZVI or SOM increased the 
      removal efficiency of PCP from 34.4 to 44.3-54.2% after 15 day cultivation. More 
      importantly, a synergistic effect of SOM and nZVI was observed on the PCP removal 
      by strain L3, and the PCP removal efficiency reached up to 75.3-84.5%. Other than 
      the biodegradation through ortho- and meta-substitution under the individual 
      application of SOM or nZVI, PCP was further biodegraded to 2,4,6-trichlorophenol 
      (TCP) through para-substitution by the isolated bacteria with the cotreatment of 
      SOM and nZVI. The main roles of the nZVI-SOM cotreatment in the biodegradation 
      included the SOM-facilitated microbial proliferation, the nZVI-promoted microbial 
      transformation of SOM, and the induced higher electron transport capacity of 
      redox Fe-PCP biocycling. These findings provide a novel insight into the action 
      of nZVI in environmental remediations.
