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.

This research presents a simple procedure for chemically modifying yeast (Saccharomyces cerevisiae) cells with nickel hexacyanoferrate (NiHCF) and ferric hexacyanoferrate, also known as Prussian blue (PB), to increase the conductivity of cell wall. Using linear sweep voltammetry, NiHCF-modified PB-modified (NiHCF/yeast PB/yeast, respectively) were found have better wall in [Fe(CN)6]3− glucose-containing phosphate-buffered solution than unmodified yeast. Spectrophotometric analysis showed that modification NiHCF had less harmful effect on viability PB. The use NiHCF/yeast PB/yeast construction yeast-based fuel allowed maximum power densities 62.66 mW/m2 94.09 be achieved. These values much higher those obtained using (42.25 mW/m2). renewed by replenishing suspension anolyte or FeCl3 salt catholyte. 77.4% 50.1% initial density
