Development of efficient electroactive biofilm in urine-fed microbial fuel cell cascades for bioelectricity generation (2020)
Journal Article
Obata, O., Salar-Garcia, M. J., Greenman, J., Kurt, H., Chandran, K., & Ieropoulos, I. (2020). Development of efficient electroactive biofilm in urine-fed microbial fuel cell cascades for bioelectricity generation. Journal of Environmental Management, 258, https://doi.org/10.1016/j.jenvman.2019.109992

The Microbial fuel cell (MFC) technology harnesses the potential of some naturally occurring bacteria for electricity generation. Digested sludge is commonly used as the inoculum to initiate the process. There are, however, health hazards and practic...
