Abstract
The effect of laxose concentration as Lactobacillus bulgaricus bacterial substrate on the cell potential produced in Microbial Fuel Cell System has been done. This study aims to determine the effect of lactose concentration as bacterial substrate, to generate electricity, maximum electric potential and determine the potential value of standard lactose (E ° Lactose.) Based on Nernst equation. The MFC system of two compartments and bridges of salt as a linkage is used in this study. Anode contains lactose with variation of concentration 3 - 7% and bacteria. The cathode contains a 1M KMO4. The electrodes used are graphite. MFC operational time is 14 days. The results showed that the lactose concentration had an effect on the cell potential produced in the MFC system. Maximum cell potential yielded at 4% lactose concentration, that is 710 mV then based on Nerst equation theory obtained E ° Lactose value in MFC system of + 0,236 V.
