Abstract

Microbial electrolysis cells (MECs) were used for production of bio-hydrogen (Bio-H2)by Enterobacter aerogenes DSM 30053 from domestic wastewater at three volumes of anode chamber in MECs 300ml, 400 ml and 500 ml were applied.  Power supply of 0.4 V, 0.6 V and 0.8 V was used applied to MECs using a regulated external voltage. The highest volume of Bio-H2 112.83 cm3 production was obtained from domestic wastewater without addition of bacteria at the anode chamber 500 ml with power supply 0.8 V. While the highest volume of Bio-H2 316 cm3 production was obtained by Enterobacter aerogenes DSM 30053 at the anode chamber 500 ml with power supply 0.4 V from domestic wastewater.
