Pretreatment of bamboo shoot shell (BSS) by a combination of alkalic salts with hydrogen peroxide (H<SUB>2</SUB>O<SUB>2</SUB>) was evaluated for its delignification effect and for its ability to enhance enzymatic saccharification of pretreated solids. By comparing different alkalic salts, the combination of 9% Na<SUB>3</SUB>PO<SUB>4</SUB>.12H<SUB>2</SUB>O and 0.3g/g H<SUB>2</SUB>O<SUB>2</SUB> (ASHP) was identified as an effective system that showed the highest delignification of 87.7% and the total reducing sugar yield of 97.1% when pretreated BSS at a solid to liquid ratio of ½0 (w/w) at 80<SUP>o</SUP>C for 2h. The delignification effect and the disruption of the lignocelluloses structure by this novel pretreatment method were deduced to be the main reasons that led to enhanced enzymatic saccharification as supported by the chemical composition analysis and the results of SEM, FTIR and XRD analyses of the untreated and alkalic salt pretreated BSS.
