Hot Compressed Water Pretreatment and Surfactant Effect on Enzymatic Hydrolysis Using Agave Bagasse

Agave bagasse is a residual biomass in the production of alcoholic beverage tequila, and therefore, it promising raw material development biorefineries using hot compressed water pretreatment (hydrothermal processing). Surfactants application has been frequently reported as an alternative to enhance monomeric sugars efficiency possibility reduce enzyme loading required. Nevertheless, surfactant’s action mechanisms enzymatic hydrolysis still not elucidated. In this work, was applied on agave for fractionation at 194 °C isothermal regime 30 min, effect non-ionic surfactants (Tween 20, Tween 80, Span Polyethylene glycol (PEG 400)) studied potential enhancer saccharification hydrothermally pretreated solids (AGB). It found that show improvement conversion yield cellulose glucose (100%) (79.76 g/L) 15 FPU/g glucan, highest enhancement obtained being 7% regarding control (no surfactant addition), PEG 400 additive. The use allows improving fermentable second-generation biorefineries.
