Ethanol is the predominant biofuel product dependent on sugar (molasses) and starch (grains) as first-generation (1G) feedstock (Table 3.1). The restriction on sugar and starch-rich biomass as petroleum-derived transportation fuels involve increased demand for food supplies with growth in the global population, clearing agricultural land [31, 32]. Because of these concerns, studies have focused on using food crops by-products as a sustainable substrate.
