Engineering HDR Seminar Series 33, 2013: Production of Biohydrogen by Rhodobacter Sphaeroides in Palm Oil Mill Effluent through Photofermentation

Ms Pretty Mori Budiman, Chem Eng postgraduate student

Date: 2013-06-27
Time: 10:00 to 11:00
Venue: Engineering Meeting Room 1, 5-4-22


Among existing hydrogen production methods, biological hydrogen production is considered to be a more environmental friendly and less energy demanding technology. Photofermentation produces biohydrogen through photo-decomposition of organic compounds by photosynthetic bacteria via nitrogenase activity. Utilization of wastewater, such as POME, is expected to produce biohydrogen in an environmentally acceptable way and to reduce the contamination level of the effluent before being discharged to the environment. In this study, POME was selected as photofermentation substrate since it contains organic acids and other nutrients which could be used to support the growth and the biohydrogen production by purple non sulfur bacteria, Rhodobacter sphaeroides NCIMB8253. Additional benefit of simultaneous COD removal in POME is also expected to occur due to organic matter consumption by the bacteria.
