Increased human, agricultural and industrial activities along with improper waste disposal leads to high levels of soil contamination and accumulation of recalcitrant contaminants in the environment. This global issue demands the use of green and sustainable technologies and soil microbial fuel cells (SMFC) can be a potential solution. We adopted minimalistic designs, based on low-cost carbon materials without any expensive catalyst and membrane, which makes the SMFCs suitable for in-field applications. We investigated the ability of the indigenous microbial population of the soil to use organic contaminants as the source of carbon and the enrichment of the electroactive consortium was monitored over time onto the electrode surface of the SMFCs. We tested performance in soil contaminated with pesticide and soil contaminated with hydrocarbons and compare the microbial enrichment process with respect to the case of non-contaminated soil.
