Simultaneous ethanol and hydrogen production by fermentation from Bon bogori (Ziziphus rugosa)

Lignocellulosic ethanol is one of the utmost promising and happening technological options available to moderate greenhouse gas emissions from transportation sector. Present study used ultrasound-assisted lime pretreated lignocellulosic biomass of Bon bogori for saccharification to obtain fermentable sugar. The saccharification process yielded 6.89% sugar. The fermentation study was conducted using wastewater sludge as a source of microorganisms to produce bio-ethanol and bio-hydrogen. The study includes optimization of fermentation process using Taguchi methodology (multi response). Four important parameters such as type of reactors (stirred tank and fluidized bed reactor), temperature, pH of operation and organic loading ratio were considered for optimization process. The optimum production of both ethanol and bio-hydrogen were found to be 0.21 mol, and 30.8 ± 0.5-mmol respectively.
