Proposal
The demand for renewable and clean energy supplies is increasing because of depleting fossil fuels and global warming. Hydrogen (H2) is the only carbon-free energy source which is regarded as the cleanest fuel since water is the only product during combustion. Bio-hydrogen (bio-H2) production is promising because many organic wastes can be utilized as feedstocks. Bacteria fermentation, a similar process taking place during food digestion in our gut system, can be utilized to produce bio-H2.
Glycerol, a waste byproduct from the manufacture of biodiesel, is a low-value chemical that can be converted intoH2. Biodiesel is a transportation fuel produced which is from algae. Converting glycerol intoH2 could be an economic advantage for many biodiesel industries. Adding fatty acids which are produced from oils such a safflower and sunflower oils can improve H2 production from glycerol during bacterial fermentation. Although bio-H2 production from glycerol through dark fermentation by using selected bacterium has been reported, the performance of H2 yield needs to be analyzed when mixed bacteria and H2-improving treatment are conducted. The main objective of this work was to establish a maximumH2 yield during the glycerol fermentation in the mixed cultures with the presence of fatty acids.
