Microbiome and transcriptomic analysis of anodic and cathodic biofilms of MEC and digested pig slurry, with DNA and RNA extraction. microbial fuel cell metagenome

The main aim of this study was to assess the performance of the bioanode and the biocathode of a lab-scale MEC in combination with anaerobic digestion as a technology for increasing the stability of the process, recovering ammonium and upgrading biogas. The evolution of the microbial community was evaluated in terms of composition and activity by the use of quantitative real-time polymerase chain reaction (qPCR) and high throughput sequencing of DNA and RNA.
