Abstract
Enzymatic and dilute acid processes were applied to study the orange bagasse hydrolysis. The moisture, ashes, lignin, cellulose, and hemicellulose contents, of the orange peels, were quantified. The xylanase and cellulase enzymes activities were quantified, as well as their optimum pH and temperatures. The pre dried orange peel biomass was pre-treated with calcium hydroxide, at preestablished conditions. The hydrolysis followed a central composite factorial 2³ design. The cellulase activity was 28.05x10-6 FPU (Filter Paper Units)/m3, the optimum pH was 4.8 and the temperature was 60°C. The results for xylanase were an activity of 199.58x10-3 U/Kg, pH 5.2, and temperature 50°C. The acid hydrolysis TRS (total reducing sugars) values varied from (9.328±0.68 mg)*10-3 TRS per Kg of biomass to (30.15±0.31)*10-3 mg TRS per Kg biomass, the most significant factor was the temperature and the least the time. The enzymatic hydrolysis TRS values varied from (77.33±3.82)*10-3 mg TRS per Kg biomass to (99.66±0.62)*10-3 mg TRS per Kg biomass, the most significant factor was the concentration of cellulase and the least the xylanase concentration.
