Impacts of alkalic salts on the pretreatment of BSS with H2O2 were evaluated.
Best performance was observed using Na3PO4·12H2O combined with H2O2.
The maximum reducing sugar yield of 97.1% was achieved in enzymatic saccharification.
The recovered hydrolyzates could be fermented into ethanol efficiently.
The pretreatment shows high potential for application in future.
