Microbial fuel cell-based sensor for Enterobacter sp. KBH6958 activity monitoring during hydrogen production: The effects of pH and glucose concentration

A microbial fuel cell (MFC) is an electricity-generating device utilising electrochemically active microorganisms as biocatalysts. Using MFC as a biosensor to monitor hydrogen fermentation in Enterobacter sp. is possible because the device depends on microbial activity for electricity output. This s...
