Batch anaerobic studies were conducted using five mixtures (M1-M5) of bovine serum albumin (BSA) and starch. The results showed that co-digestion of BSA and starch had a positive impact on the methane production. The highest methane production of 288mL, the highest methane yield of 360mL CH(4)/g COD(added), and the highest maximum methane production rate of 62mL CH(4)/d were achieved for M4 (20% BSA and 80% starch). Most of the particulate proteins (90%) as well as particulate carbohydrates (95%) were degraded in the first 3days. The hydrolysis coefficients of particulate proteins and particulate carbohydrates ranged from 0.65 to 1.01d(-1) and from 0.53 to 1.06d(-1), respectively. The highest methane production was achieved at C:N ratio of 12.8 for M4. For BSA only, propionic acid was the main volatile fatty acid (VFA), while for the starch only, butyric acid was the predominant VFA.
