Abstract:
Saccharification of saw-dust of deodar (Cedrus deodara) and kail (Pinus wallichiana) was conducted under varied conditions of temperature, period of heating, and acid concentration. The hydrolysed products from pre main, and post-hydrolysis were pentoses, oligo saccharides and mono-saccharides, respectively. The glucose content ranged from 2.63 to 25.29% in the saw-dust of deodar and 2.15 to 25.17% in kail. The treatment of saw-dust with 5-70% H2SO4 dissolved and hydrolyed 16.60-54.93% and 13.01- 52.98% of original material of deodar and kail, respectively. Higher acid concentration and prolonged period of heating increased the amount of hydrolysed and dissolved material in hydrolyzate. The chemical conversion of wooa was not only affected by the experimental conditions but also by the nature of wood material.
