Denitrification Performance of Solid Carbon-Releasing Particle Electrodes in a Bioelectrochemical System: Iron-Manganese Oxide-Enhanced Electron Migration
High-throughput microbial sequencing and analysis were performed. The activated sludge before inoculation was named YS; the electrode biofilm with corncob + iron manganese oxide solid slow-release carbon particles was named DZ; the electrode biofilm with corncob + iron manganese oxide solid slow-release carbon particles under applied voltage was named DJ. Each group included three biological replicates. All samples were sealed, stored in an insulated container with dry ice, and sent for DNA sequencing using the Illumina MiSeq platform at Shanghai Personal Biotechnology Co., Ltd.
