Abstract

The present study established a new dual-phase biological system for electricity production from potato waste (PW). During the initial phase, commercially available glucoamylase was used to make hydrolysis of PW to generate PW hydrolysate. Results revealed that a hundred g PW could generate 30 g hydrolysis solid and 750 ml PW hydrolysate. During the second phase, the soluble PW hydrolysate was used to feed for electricity production from microbial fuel cell (MFC). The highest voltage of 1.1 V was achieved. The power density attained the highest amount of 93 mW/m³ at the external resistance was 1091 ?. Coulombic efficiency of 20% was obtained to evaluate MFC performance. This might be possibly used to convert high starch compounds into biofuel generation that might cut the cost of commercial biofuel generation.
