Electrical Conductivity in a Mixed-Species Biofilm Academic Article uri icon


  • ABSTRACTGeobacter sulfurreducenscan form electrically conductive biofilms, but the potential for conductivity through mixed-species biofilms has not been examined. A current-producing biofilm grown from a wastewater sludge inoculum was highly conductive with low charge transfer resistance even though microorganisms other thanGeobacteraceaeaccounted for nearly half the microbial community.
