•First report on Zn (II) containing wastewater treatment in a CW-MFC.•The expression of CzcA increased with increasing Zn (II) concentration.•Proteobacteria was the dominant host bacteria of CzcA gene.•Microorganisms exerted anti-stress effects to Zn (II) contaminated wastewater.
The main aim of this work was to characterize the microbial community structure and resistance gene (CzcA) shifts in up-flow constructed wetlands-microbial fuel cell (CW-MFC) treating Zn (II) contaminated wastewater. Two CW-MFC devices were operated, i.e. the experimental group (EG) treating Zn (II) wastewater, and the control group (CG) treating Zn (II)-free wastewater. The results showed the CW-MFC combination exhibited good removal efficiency on Zn (II), while the average voltage, the power density and the removal rates (TP, TN, NH4+-N and COD) significantly reduced (p |

The microbial community structure showed that the Zn (II) significantly reduced the abundance of some functional genus (p < 0.05), such as Ochrobactrum, Nitrosomonas, Pseudomonas and Dechloromonas. Zn (II) inhibited the microbial richness in the anode, but it played a positive role in the cathode. Anew, the expression of the CzcA in the CW-MFC was promoted by Zn (II), particularly in the cathode.</description><identifier>ISSN: 0960-8524</identifier><identifier>EISSN: 1873-2976</identifier><identifier>DOI: 10.1016/j.biortech.2020.122867</identifier><identifier>PMID: 32007853</identifier><language>eng</language><publisher>England: Elsevier Ltd</publisher><subject>Bioelectric Energy Sources ; Bioelectricity ; Constructed wetlands ; CzcA gene ; Electricity ; Electrodes ; Microbial fuel cell ; Microbiota ; Waste Water ; Wetlands ; Zinc ; Zn (II) contamination</subject><ispartof>Bioresource technology, 2020-04, Vol.302, p.122867-122867, Article 122867</ispartof><rights>2020 Elsevier Ltd</rights><rights>Copyright © 2020 Elsevier Ltd.
