چکیده
The need for energy resources is growing all the time, which means that more fossil fuels are needed to provide them. People prefer consume chicken as a source of protein, and this creates an abundance waste. Thus, microbial fuel cells represent new technological approach with potential generate electricity through action electrogenic bacteria toward manure, while reducing manure. This study investigated effect different pretreatment (thermal, alkaline, sonication pretreatment) manure improve performance membrane-less cell (ML-MFC). Statistical response surface methodology (RSM) central composite design (CCD) under quadratic model was conducted optimization ML-MFC focusing on COD removal efficiency (R2 = 0.8917), biomass 0.9101), power density 0.8794). demonstrated highest (80.68%), (7.8539 mg/L), (220 mW/m2) were obtained when conditions 140 °C, 20 kHz, pH 10. polarization curve best condition plotted classify behavior ML-MFC. kinetic growth Bacillus subtillis (BS) showed that, in treated specific rate µ 0.20 h−1 doubling time Td 3.43 h, whereas, untreated 0.11 6.08.
