•Granules from four brewery waste UASB digesters were electrically conductive.•Geobacter, Syntrophobacter and Desulfovibrio spp. were the dominant members.•Granules conductivity was moderately correlated with only Geobacter spp. abundance.•This study suggest that Geobacter spp. are a major contribut...
