The objective of the research was to investigate the effect of biomass loading, alkali (NaOH) concentration and pre-treatment time on the yield of glucose obtained following alkaline pre-treatment and enzymatic hydrolysis of oilseed rape (OSR) straw. A maximum glucose yield of (440.6+/-14.9)g glucose kg<SUP>-1</SUP> biomass was obtained when OSR straw was pre-treated at a biomass loading of 50gkg<SUP>-1</SUP> and an alkali concentration of 0.63moldm<SUP>-3</SUP> NaOH for 30min. The energy efficiency of glucose extraction (0.39kg glucose MJ<SUP>-1</SUP> consumed) was highest when OSR straw was pre-treated at a biomass loading of 50gkg<SUP>-1</SUP> and an alkali concentration of 0.63 or 0.75moldm<SUP>-3</SUP> for 30min. The study demonstrated alkaline pre-treatment of OSR straw is superior to acid pre-treatment in terms of glucose yield and energy efficiency.
