During treatment, the concentration of DO, pH, voltage/open
circuit voltage (V), current density (I) and power density were
determined. Power density was obtained by varying the external
resistances from 1000 to 50 O when stable voltage outputs were
observed. After 144 h of cultivation, the growth and fatty acid profiles
of microalgae and COD removal of food waste were calculated.
The control group inoculated C. vulgaris in optimal initial density at
0 h, but without connecting anode and cathode, while other conditions
were same as MFC reactors was performed.
