Comparison of delignified coconuts waste and cactus for fuel-ethanol production by the simultaneous and semi-simultaneous saccharification and fermentation strategies

Abstract: h i g h l i g h t s Sequential Alk-H 2 O 2 /NaOH pretreatment was developed. FTIR, SEM, X-ray and crystallinity indexes have evidenced modifications in solids. Delignified MCF was more susceptible the enzymatic action. SSSF strategy allowed to obtain higher ethanol production than SSF. Step of presaccharification had a positive effect on the overall ethanol yield.

“…The presaccharification performed in SSSF is important to supply glucose in concentrations high enough to activate the yeast at the beginning of fermentation (Santos et al 2010). Presaccharification improves ethanol yield and reduces enzyme inhibition (such as glucose and cellobiose in high concentration) and fermentation time (Gonçalves et al 2014;Baeyens et al 2015;Cotana et al 2015).…”

“…Os resíduos provenientes das indústrias de grãos, madeira, papel, entre outras, e que são, na maioria dos casos subutilizados, são denominados de biomassa residual. A biomassa é constituída basicamente por três componentes principais, a celulose, a hemicelulose e a lignina (Gonçalves et al, 2014).…”
