Abstract / Full Text

The effectiveness of ozone pretreatment of pine wood for subsequent fermentation in sugars is studied. Kinetic curves for the ozone consumption by the samples with different water contents were obtained, and the optimum wood moisture values are determined during ozonation (50–70 wt %). It is found that the yield of reducing sugars in the enzymatic reaction grows in proportion to the amount of absorbed ozone and reaches a maximum at an ozone consumption of around 3 mmol/g of biomass, which corresponds to 2 mol-equivalent of O3/C9PPU lignin contained in the initial material. Upon prolonged ozonation, the yield of sugars falls.
