摘要：This study aimed to determine bio-ethanol potential of poultry manure.The manure was hydrolyzed by dilute H2SO4(0.2, 0.4, 0.6, 0.8 and 1 M) at temperature of 100 and 130°C for 30 min. Maximum glucose (115.6 g/l) was obtained from hydrolysis of 100 g poultry manureby 0.8MH2SO4at 100°C for 30 min. The study shows that treatment of poultry manure releases more total reducing sugar using 0.8 M H2SO4. Refractometryanalysis of the fermented hydrolysate gavemaximum ethanol concentration of 5% w/v with 0.8 M H2SO4and 4, 4, 3and 2.5% of ethanol with 1, 0.6, 0.4 and 0.2 M H2SO4hydrolysis at 130°C for 30 min,respectively. Treatment with 0.8M acid is an effective way that results to maximum yield and treatment with 0.2M acid is the least effective. The optimum fermentation time is 24 h.
