Abstract
Microbial fuel cells with graphene based cathode and anode is the study of interest. Present work shows the capacity of sub-himalayan soil of Dehradun region of Uttarakhand, India holds potential to cater to power production from soil and organic waste matter. This can be speculated to power less energy intensive devices at the smallest level. Peak voltage of 0.69 V and current density datas are reported.Renewable energy utilization with such samples represents a sustainable usage. The soil bacterias are capable to metabolize the metal substances in the soil through symbiosis. Electric bacteria create conductive pili called nanowires enabling them to transfer electron and this can be utilized effectively.Direct electron transfer mechanisms have been investigated for this work. The biofilm developed by soil bacterias represent the central idea in making value from waste matter.
Highlights
In a microbial fuel cell (MFC), microorganisms i.e. bacteria oxidize prganic matter, producing protons and electrons
Shewanella appeared in a comic book as "Shewy, the Electric Bacterium" in educational kits that are available for students and hobbyists to understand how microbes contribute to charge density in the soil by giving out electrons after consuming organic matter from it [1]
This work is taken into account because it shows that the electrogenic bacterium which may add power to a microbial fuel cell exist in Uttarakhand i.e. Indian soil yet
Summary
In a microbial fuel cell (MFC), microorganisms i.e. bacteria oxidize prganic matter, producing protons and electrons. Shewanella appeared in a comic book as "Shewy, the Electric Bacterium" in educational kits that are available for students and hobbyists to understand how microbes contribute to charge density in the soil by giving out electrons after consuming organic matter from it [1]. This work is taken into account because it shows that the electrogenic bacterium which may add power to a microbial fuel cell exist in Uttarakhand i.e. Indian soil yet. And poisonouschemicals weren't required for mediate electron transfer. Such technology has the likelihood to be used even for rural and concrete waste management which has cleanup of stream, production of electricity at the same time
