Fig. 3From: Enhanced methane production from cellulose using a two-stage process involving a bioelectrochemical system and a fixed film reactorSpecies-level microbial diversity of microorganisms in the two-stage processes. The suspended cultures in the cathodic and anodic sides of the BES, or the left and right sides of the NBES, with the (BES→ and NBES→) FFR processes, or in the CFT-attached fractions in the (BES→ and NBES→) FFR-C processes were determined. Species with low similarity (< 97%) and low abundance (< 1.0%) were included in the “unclassified bacteria” and “others” categories, respectivelyBack to article page
