Thermophilic fermentation hydrogen production from xylose by Thermotoga neapolitanaDSM 4359 using a 3L-CSABR system |
| 초록 |
Biohydrogen production from xylose by Thermotoga neapolitana was investigated in continuously stirred anaerobic bioreactor (CSABR). The highest hydrogen production of 32.1 ± 1.6 mmol-H2/L and maximum biomass concentration of 959.63 ± 47.9 g/L were obtained at initial xylose concentration of 5.0 g/L. To develop a large scale biohydrogen production system as well as overcome the problems in small batch culture, an CSABR was tested on T. neapolitana in both pH-uncontrolled batch culture and pH-controlled batch culture. The results showed that the production level of H2 in a pH-controlled batch culture was much higher than those from a pH-uncontrolled batch culture for H2 production. In order to study the precise effect of a stable pH on hydrogen production, and metabolite pathway involved, cultures was conducted with pH-controlled at different levels ranging from 6.5 to 7.5. The maximum H2 yield of 2.8 ± 0.14 mol-H2mol-1 xyloseconsumed was measured while the pH was maintained at 7.0. The acetic acid and lactic acid production were 2.98 ± 0.15 g/L and 0.36 ± 0.02 g/L, respectively. |
