Abstract
Native outer, inner and whole bark, and paper mill waste bark have been studied and compared. Extraction with cold and warm water and different chemical pretreatments (H2SO4, NaOH, and NaClO) have been used to improve the accessibility of the cellulose fraction of the substrate to the enzymes and hence to increase the yield of formation of glucose.
