, soil from refuse dump, soil mixed with cow dung and soil from sewage deposits were examined for a period of 49 days. This was done to determine the most suitable soil for the microbial fuel cell technology. Two different experimental step-ups were utilized; the first set-up was prepared with four different soil samples of equal quantities and the same electrode type for the first 5 weeks. The second set up used the soil with the best yield from the first set-up to further prepare four more cells during the start of the 6<sup>th</sup> week. This was done to increase the overall power output because that of the first set-up was low. The entire set-ups were connected in parallel. The results obtained from the first set up showed that the soil sample from gutter gave the highest output voltage compared to other soil samples with the value of 1.49 volts; while the maximum voltages of the soil samples obtained from refuse dump, mixture of soil and cow dung and sewage deposits were 0.90, 1.40 and 1.21 volts respectively.&picture=http://www.aascit.org/aascit/decorators/img/journal/933.jpg)

The effect of different soil feedstock for Microbial Fuel Cell development is presented. Four different soil samples namely; the soil from gutter (drainage), soil from refuse dump, soil mixed with cow dung and soil from sewage deposits were examined for a period of 49 days. This was done to determine the most suitable soil for the microbial fuel cell technology. Two different experimental step-ups were utilized; the first set-up was prepared with four different soil samples of equal quantities and the same electrode type for the first 5 weeks. The second set up used the soil with the best yield from the first set-up to further prepare four more cells during the start of the 6th week. This was done to increase the overall power output because that of the first set-up was low. The entire set-ups were connected in parallel. The results obtained from the first set up showed that the soil sample from gutter gave the highest output voltage compared to other soil samples with the value of 1.49 volts; while the maximum voltages of the soil samples obtained from refuse dump, mixture of soil and cow dung and sewage deposits were 0.90, 1.40 and 1.21 volts respectively.
