BACKGROUND An innovative microbial fuel cell (MFC) using Cupriavidus sp. S1 as the biocathode catalyst was developed to improve nitrogen removal from low carbon/nitrogen (C/N) wastewater. RESULTS The desirable external resistance was 100 Ω in this study, with an optimal total nitrogen (TN) removal efficiency of 95.71%, and a maximum current density and power density of 7583.89 ± 318.11 mA m−3 and 932 mW m−3 at C/N = 2, respectively, which initially confirmed the ability of Cupriavidus sp. S1 to obtain electrons from the electrode. The maximum tolerance of the system at Rext of 100 Ω was C/N = 1, with a TN removal efficiency of 90.87%. Compared with the open circuit, the TN removal increased by approximately 21.60% and 52.02% at C/N = 2 and 1, respectively, which expanded the application area for the dominant denitrifying bacteria S1. Additionally, the system exhibits the obvious merits of less sludge production, low energy consumption and the recovery of some energy. CONCLUSION Based on these results, domesticated Cupriavidus sp. S1 possesses electrochemical activity. Thus, the system has great potential for efficient and cost‐effective nitrogen removal from nitrate‐containing low C/N wastewater and energy recovery. © 2019 Society of Chemical Industry

h i g h l i g h t sFeeding with glucose obtained higher AYR decolorization efficiency than acetate. Diverse cathodic bacterial communities were observed with different co-substrates. Glucose-fed condition was dominated with Citrobacter, Enterococcus and Alkaliflexus. Acetate-fed condition was dominated with Acinetobacter and Achromobacter. Co-substrate types impacted performance and the cathodic bacterial communities. a r t i c l e i n f o t r a c tSelective enrichment of cathodic bacterial community was investigated during reductive decolorization of AYR fedding with glucose or acetate as co-substrates in biocathode. A clear distinction of phylotype structures were observed between glucose-fed and acetate-fed biocathodes. In glucose-fed biocathode, Citrobacter (29.2%), Enterococcus (14.7%) and Alkaliflexus (9.2%) were predominant, and while, in acetate-fed biocathode, Acinetobacter (17.8%) and Achromobacter (6.4%) were dominant. Some electroactive or reductive decolorization genera, like Pseudomonas, Delftia and Dechloromonas were commonly enriched. Both of the higher AYR decolorization rate (k AYR = 0.46) and p-phenylenediamine (PPD) generation rate (k PPD = 0.38) were obtained fed with glucose than acetate (k AYR = 0.18; k PPD = 0.16). The electrochemical behavior analysis represented a total resistance in glucose-fed condition was about 73.2% lower than acetate-fed condition. The different co-substrate types, resulted in alteration of structure, richness and composition of bacterial communities, which significantly impacted the performances and electrochemical behaviors during reductive decolorization of azo dyes in biocathode.

“…It was recently shown that nitrate and also nitrite could effectively be used to drive current generation and simultaneous carbon and nitrogen removal. Intensive studies have been carried out to determine the feasibility of carbon and nitrogen removal using MFCs (Feng et al, 2015;Mook et al, 2012;Ryu et al, 2013;Sayess et al, 2013;Virdis et al, 2010;Xie et al, 2011;Zhang et al, 2013). Removal of carbon and nitrogen from food, swine, and aquaculture wastewater using MFCs has been increasingly reported (Blanchet et al, 2015;ElMekawy et al, 2015;Lim et al, 2012;Ryu et al, 2013;Vilajeliu Pons et al, 2015).…”

“…Virdis et al (2010) found carbon and nitrogen removal were 100% and 94.1 ± 0.9 under the COD/N ratio of 4.49 ± 0.01 and DO of 4.35 ± 0.08 mg/L at the cathode, produced through specific aeration. Zhang et al (2013) developed a single chamber MFC with a rotating biocathode, and they found that the removal efficiencies of TOC and TN were 85.7 ± 7.4% and 91.5 ± 7.2% with a maximum power output of 585 mW/m 3 with a COD/N ratio of 5:1. These proved that MFCs had great potential to be applied in removing carbon and nitrogen from wastewater.…”
