Microbiome analysis of raw and digested pig slurry, and anode biofilms of MEC and MFC. anaerobic digester metagenome

In the present study, BES operation in combination with AD was investigated in batch assays in order to improve COD removal and nitrogen recovery from a complex waste flux as pig slurry, compared to raw pig slurry treatment in BES. Furthermore, charge production, its relation with cation transport through the membrane and the influence of the other cations on ammonium migration flux was assessed. Finally, the evolution of microbial populations (total eubacteria and archaea) on the anode biofilm under MFC and MEC operation mode were studied.
