Yeast-based biomass, immobilised in polyvinyl alcohol (PVA) cryogels, was used as a biosorbant material for the recovery of platinum (PtCl62−) from aqueous solutions. The resulting biomass-Pt matrices were then employed directly as an electro-catalytic anode in a fuel cell configuration to generate electrical energy from renewable sources such as glucose and ethanol. We suggest an integrated strategy incorporating the derivation of a high-value product from a bioremediative process with a view towards producing energy from renewable fuels such as glucose and ethanol.
