Abstract
Abstract In this study, the petroleum hydrocarbon‐contaminated soil was used as both inoculation and carbon source simultaneously to enrich exoelectrogenic bacteria for using in microbial fuel cell system and it demonstrated working output power density at around 220 mW m −2 . The feasible electrochemical properties have displayed by means of cyclic voltammetry and dual‐chamber MFCs experiments. Moreover, two species of exoelectrogens were isolated belonging to Geobacter sp. and Ochrobactrum sp., respectively. This work evaluates the capability of naturally occurring petroleum‐degrading species to produce electric current in bioelectrochemical system. To the best of our knowledge, this is the first time when ecological information on electroactive, petroleum‐degrading consortium is provided.
Key findings
