Abstract

Microbial fuel cells, also known as biological fuel cells, use bacteria to convert biodegradable materials such as wastewater pollutants into electricity. However, limited studies revealed the high bioelectricity generation using a mediator-less MFC. This study isolated an exoelectrogen E. faecium YC 201, inoculated to a mediator-less MFC and obtained a high power density. Results show that the power generation reached a maximum of 121.3 ± 4.2 mW/m 2 that was higher than those of other similar MFCs reported in the past literature. Substrate types significantly affected electricity generation and the optimal substrate for electricity generation was glucose. The riboflavin was identified as possible mediator for the mediator-less MFC that was self-excreted by E. faecium YC 201. To our knowledge, this is the first time to clearly reveal the electricity characteristics of exoelectrogen E. faecium YC 210.
