Microbial fuel cells (MFCs) are a candidate for green energy sources due to microbes’ ability generate charge in their metabolic processes. The main problem MFCs is slow transfer between microorganisms and electrodes. Several methods improve have been used until now: modification of by conductive polymers, use lipophilic mediators, nanomaterials. We created an MFC with graphite anode, covering it 9,10-phenatrenequinone polypyrrole-modified Saccharomyces cerevisiae without 10 nm sphere gold nanoparticles. was evaluated using cyclic voltammetry power density measurements. peak current from measurements increased 3.76 mA/cm2 5.01 bare yeast, respectively. polypyrrole- nanoparticle-modified yeast reached maximum 150 mW/m2 PBS 20 mM Fe(III) glucose, load kΩ. same the wastewater 179.2 mW/m2. These results suggest that this configuration can be transfer.
