Impact of applied voltage on methane generation and microbial activities in an anaerobic microbial electrolysis cell (MEC)
TL;DR: In this paper, the authors explored the effects of applied voltages on the performance of MEC and the microbial activities under anaerobic conditions and concluded that the higher voltage led to the greater plasmatorrhexis, lower growth rate and lower metabolic activity.
