Fig. 3From: Less biomass and intracellular glutamate in anodic biofilms lead to efficient electricity generation by microbial fuel cellsSpecies-level composition of archaea and bacteria in the anodic biofilm (Anode) and fermentation broth (Broth) of MFC-1 and MFC-2. Samples were obtained from MFC-1 and MFC-2 anodic biofilms and fermentation broths after 30 days and 90 days of operation, respectively. Not clustered (< 99% similarity) and low-abundance (< 1.0%) sequences were included in Unclassified and Others, respectivelyBack to article page
