Voltage production using metabolic activities of Azatobacter species and other soil microbial flora in rice field using microbial fuel cell and microbial solar cell technology.

The voltage generation from metabolic reactions of bacteria due to exudates in rhizosphere of rice crop was demonstrated by Azatobacter species and natural soil microbial flora using microbial fuel cell. It was observed that voltage generated by microbial fuel cells increased from 0.5 V to 98.0 V till 60th day of the crop for one square feet area of rice field in laboratory conditions and on 90th day of the crop voltage was 1V maintained during day time. The range of increase in voltage was dependent on the intensity of sunlight. It was estimated that if one square feet of rice plantation can produce 1V after 90th day by this method, then in case of one acre of plantation 43560 V could be generated on the 90th day of the crop on each successive day. That might produce rice and enough voltage in an eco-friendly manner.
