Summary: | Worldwide energy system utilized fossil fuels as the source of combustion. However, it cannot be sustainable and decreases from time to time. Exploration of a new sustainable energy has been conducted around the word in order to replace conventional fossil fuels. Hydrogen has been considered as a potential fuel for the future since it is carbon-free and oxidized to water as a combustion product. There are several methods to produce hydrogen. Either from mushroom cultivation waste, sweet potato or many more organic wastes in order to generate fermentative hydrogen production. In this study, Palm Oil Mill Effluent (POME) was used as a substrate carbon source. The optimization of hydrogen production using polyethylene glycol (PEG) immobilized sludge was investigated by using a batch test. It was found that a maximum hydrogen production rate that can be produce by immobilized sludge was 339 mL/L-POME/h at the optimal
amount of biomass (10 mg VSS/ g bead), pH 6.5 and PEG concentration (10% w/v). Therefore, immobilized biomass and PEG really helps to maintain a higher cell density.
More importantly, it not only enhanced hydrogen production but can also tolerate with the harsh environment and produce hydrogen at wide range of pH. The present results indicate that potential of PEG- Immobilized sludge for large scale operations and play an important role in stable and continuous hydrogen production. |
