英文摘要	A new hydrogen-producing bacterial strain Ethanoligenens harbinense B49 was examined for its capability of H-2 production with glucose as sole carbon source. The H-2 production was significantly affected by the concentration of the yeast powder and phosphate in the synthetic medium. The optimized concentration of yeast powder was 0.3-0.5 g/L and the maximum hydrogen yield was obtained at the concentration of phosphate about 100-150 mmol/L. The dynamics of hydrogen production showed that rapid evolution of hydrogen appeared to start after the middle-phase of exponential growth (about 8 h). The maximum H-2 yield and specific hydrogen production rate were estimated to be 2.26 mol H-2/mol glucose and 27.74 mmol H-2/g cell, respectively, when 10 g/L of glucose was present in the medium. The possible pathway of hydrogen production by Ethanoligenens sp. B49 during glucose fermentation was oxidative decarboxylation of pyruvate and the NADH pathway.
