A comparative study of the enzymatic hydrolysis of batch organosolv-pretreated birch and spruce biomass.

ABSTRACT: A shift towards a sustainable and green society is vital to reduce the negative effects of climate change associated with increased CO₂ emissions. Lignocellulosic biomass is both renewable and abundant, but is recalcitrant to deconstruction. Among the methods of pretreatment available, organosolv (OS) delignifies cellulose efficiently, significantly improving its digestibility by enzymes. We have assessed the hydrolysability of the cellulose-rich solid fractions from OS-pretreated spruce and birch at 2% w/v loading (dry matter). Almost complete saccharification of birch was possible with 80 mg enzyme preparation/g_solids (12 FPU/g_solids), while the saccharification yield for spruce was only 70%, even when applying 60 FPU/g_solids. As the cellulose
