ABSTRACT
Energy crisis faced by the global community requires a feasible solution in order to accomplish sustainable energy resources. For the past few decades, biofuels seem to be promising alternatives to fossil fuel consumption. As a result, breakthroughs in biofuel studies have received enormous attention as biofuels derived from lignocellulosic residue are regarded as eco-friendly. One of the future fuels is biobutanol, which has proper ignition properties. Biobutanol derived from agricultural residues is seen as an ideal solution in the biofuels industry as it helps to produce green energy from cheap resources and at the same time contributes in the mitigation of waste from agricultural sectors. In this paper, several known and novel substrates are discussed for their potential to be used as substrates in production of biobutanol via acetone–butanol–ethanol (ABE) fermentation.
