AB  - In order to increase the hydrogen yield from glucose, hydrogen production by 
      immobilized Rhodopseudomonas faecalis RLD-53 using soluble metabolites from 
      ethanol fermentation bacteria Ethanoligenens harbinense B49 was investigated. The 
      soluble metabolites from dark-fermentation mainly were ethanol and acetate, which 
      could be further utilized for photo-hydrogen production. Hydrogen production by 
      B49 was noticeably affected by the glucose and phosphate buffer concentration. 
      The maximum hydrogen yield (1.83 mol H(2)/mol glucose) was obtained at 9 g/l 
      glucose. In addition, we found that the ratio of acetate/ethanol (A/E) increased 
      with increasing phosphate buffer concentration, which is favorable to further 
      photo-hydrogen production. The total hydrogen yield during dark- and 
      photo-fermentation reached its maximum value (6.32 mol H(2)/mol glucose) using 9 
      g/l glucose, 30 mmol/l phosphate buffers and immobilized R. faecalis RLD-53. 
      Results demonstrated that the combination of dark- and photo- fermentation was an 
      effective and efficient process to improve hydrogen yield from a single 
      substrate.
