Feasibility study and kinetics of biohydrogen production by Escherichia coli from hydrolyzed sago wastewater

The demand of hydrogen gas (H2) has increased considerably in recent years since it is a clean energy source and used as feedstock for some industries. However, H2 is most commonly produced from non-renewable sources that is considered as a less ecofriendly process. To avoid any environmental issue...
