title: Metatranscriptome of biocathode MCL at two potentials: Sample O2A
design: "Four reactors inoculated with the same inoculum were grown at a set potential of 310 mV SHE until current density stabilized, then two of them were shifted to a more positive potential (470 mV) and two remained at 310 mV for 48 hours before samples were harvested for RNA extraction.  This experiment was repeated with four more reactors inoculated with a new cell suspension from the same source electrode. "
