Abstract

In this study we tried to convert the chemical energy to electrical energy by using microbial fuel cell (MFC) consist of two chambers (anode and cathode) in presence of bacteria (Escherichia coli, pseudomonas aeroginosa ) and yeast (Saccharomyces cervesia) in the anode chamber to generate electrons. The system was started with glucose concentration 5gm/l in different pH value from (5-8). From the results we get the great generation of electricity with S. cervesia at pH 5 and the maximum voltage was 833mv. In case of bacteria that used in our experiment, the suitable pH for generation the electricity was (7).

Key findings

  • Microbial fuel cell with Saccharomyces cervesia at pH 5 generates high electricity
  • Bacteria (Escherichia coli, pseudomonas aeroginosa) suitable pH for electricity generation is 7
  • Glucose concentration of 5gm/l is used in the experiment
