Abstract In this study, an indigenous Clostridium butyricum CGS2 strain was isolated from highly efficient anaerobic hydrogen-producing sludge. Preliminary tests show that the C. butyricum CGS2 strain exhibited good hydrogen producing activity. Response surface methodology (RSM) was then applied to identify the optimal conditions for hydrogen production of C. butyricum CGS2 using carbon substrate concentration, temperature and pH as the primary operation parameters. First, one-level experiments were done in shake flasks to examine which type and concentration of carbon source was most efficient for hydrogen production. The results show that sucrose at a concentration of 20000 mg COD/l gave the highest hydrogen production rate (vH2) of 262.3 ml/h/l. Based on this result, the effect of pH and sucrose concentration on hydrogen production was further investigated in a fermenter to determine the center point for RSM experimental design. It was found that at a pH of 5.5 and a sucrose concentration of 20000 mg COD/l, the highest hydrogen yield (YH2) of 2.25 mol H2/mol sucrose was obtained, as total hydrogen production was nearly 4.9 l. Hence, the aforementioned conditions was used as the center point for RSM design. Using YH2 as the performance index, the optimum condition predicted from RSM was pH=5.2, temperature=35.1oC, and sucrose concentration=22.5 g COD/l. Under this condition, the hydrogen content was 58.5%, vH2 was 0.54 l/h/l, total hydrogen production was 7.2 l, and YH2 was 2.91 mol H2/mol sucrose. On the other hand, when vH2 was used as the performance index, the optimum condition was pH=5.36, temperature=35.1 oC, and sucrose concentration=26.1 g COD/l. This condition gave a hydrogen content of 63.3%, a YH2 of 3.26 mol H2/mol sucrose, total hydrogen production of 10.5 l, and a vH2 of 0.50 l/h/l. The validity of RSM predictions was confirmed by experimental results, suggesting that using RSM design could attain an optimal culture condition for C. butyricum CGS2 to enhance its hydrogen production performance. In the next experiments, the optimal culture condition predicted by RSM design was used to perform continuous hydrogen production in a CSTR process. It was found that the pH (5.36) was too low to limit cell grow, resulting in cell wash-out even at a high HRT of 12 h, whereas maximal hydrogen production performance was attained when the pH was controlled at 6.5. Therefore, the culture condition for continuous hydrogen fermentation was modified by using pH 6.5 instead of 5.36. With the modified condition, the reactor was operated at a progressively decreased HRT from 8 h to 2 h. The results show that operation at HRT=8 h allowed a 7 fold increase (from 0.70 to 5.31 mol H2/mol sucrose) in hydrogen yield when compared with control run. The hydrogen production also marked increased from 0.11 l/h/l to 0.90 l/h/l. The hydrogen content increased to 50%. As the HRT decreased, the hydrogen producing efficiency increased. The highest hydrogen production rate (1.34 l/h/l) and yield (4.40 mol H2/mol sucrose) was obtained when the system was operated at HRT=3 h. Finally, the experimental results were subject to numerical simulation with a steady-state kinetic models, and the model appeared to describe the data satisfactorily well.
