- OTU 4 closely similar (99.7%) to environmental Geobacter and to Geobacter lovleyi Geo 7.1A (97.16%); 13-16% relative abundance in active HUSB MFC anodes; absent in settler line; not detected in primary treated wastewater. Other delta-proteobacteria + Bacteroidia (OTUs 1+2) characterize HUSB line.
