title: Eco-friendly Power Generation and Biodegradation of Organic Pollutants in Pharmaceutical wastewater Using MnCo2O4-CV Electrode in Dual Microbial Fuel Cells
design: Biofilm DNA was extracted using the DNeasy PowerBiofilm Kit (Qiagen) and quantified with Qubit 4.0. The 16S rRNA gene was PCR-amplified with universal primers and Illumina adapters. Libraries were prepared, indexed, purified with AMPure XP beads, and sequenced on an Illumina NovaSeq 6000.
