Microbiome characterization of MFCs used for the treatment of XXXX manure.

@entity1707 @entity1568 @entity37816 @entity22137
Conventional @entity1707 manure treatment is performed by anaerobic digestion, but @entity1568 is not treated. Microbial Fuel Cells (MFCs) allow organic matter and @entity1568 removal with concomitant electricity production. MFC microbiomes treating industrial wastewaters as @entity1707 manure have not been characterized. In this study, a multidisciplinary approach allowed microbiome relation with nutrient removal capacity and electricity production. Two different MFC configurations ( @entity37816 ) were used to treat @entity1707 manure. In C-1, the nitrification and denitrification processes took place in different compartments, while in @entity37816 , simultaneous nitrification-denitrification occurred in the cathode. Clostridium disporicum and @entity22137 were identified in the anode compartments of both systems. C. disporicum was related to the degradation of complex organic matter compounds and @entity22137 to electricity production. Different nitrifying bacteria populations were identified in both systems because of the different operational conditions. The highest microbial diversity was detected in cathode compartments of both configurations, including members of Bacteroidetes, Chloroflexiaceae and Proteobacteria. These communities allowed similar removal rates of organic matter (2.02-2.09kg CODm(-3)d(-1)) and @entity1568 (0.11-0.16kgNm(-3)d(-1)) in both systems. However, they differed in the generation of electric energy (20 and 2mWm(-3) in C-1 and @entity37816 , respectively).
