The range of compounds include, but by no means limited to, acetate , glucose , starch , cellulose , wheat straw ,
pyridine , phenol , p-nitrophenol and complex solutions such as domestic waste
water , brewery waste , land file leachate , chocolate industry waste , mixed fatty
acids and petroleum contaminates . Within these systems less biomass is also generally
produced then their equivalent aerobic processes and without the need for an energy intensive aeration
process less energy is required . MFCs for the large scale treatment of wastewaters still face
problems of scale up from laboratory experiments and slow rates of substrate degradation.
