The objective of this study was to investigate (i) the optimal
inoculum density of C. vulgaris in the cathode chamber for promoting
bioelectricity generation performance of MFC and food waste
treatment; (ii) effects of MFC stimulation on the total lipid content
and fatty acid compositional profiles of C. vulgaris. The optimized
performance of the system was evaluated in terms of substrate
(COD) removal efficiency and electrochemical properties
(maximum power generation).
