Biohydrogen production from food waste in batch and semi-continuous conditions: evaluation of a two-phase approach with digestate recirculation for pH control [PDF]
, 2013 The research investigated the production of Biohythane in a two-phase anaerobic digestion process treating food waste as substrate. Preliminary batch assays were carried out at initial organic loadings of 15, 20, 25 and 30 kg TVS m?3, in stirred 1.5-l ...

Hydrogenases and Hydrogen Metabolism of Cyanobacteria [PDF]
Microbiology and Molecular Biology Reviews, 2002 SUMMARY Cyanobacteria may possess several enzymes that are directly involved in dihydrogen metabolism: nitrogenase(s) catalyzing the production of hydrogen concomitantly with the reduction of dinitrogen to ammonia, an uptake hydrogenase (encoded by hupSL) catalyzing the consumption of hydrogen produced by the nitrogenase, and a

Syntrophic growth on formate: a new microbial niche in anoxic environments [PDF]
, 2008 Anaerobic syntrophic associations of fermentative bacteria and methanogenic archaea operate at the thermodynamic limits of life. The interspecies transfer of electrons from formate or hydrogen as a substrate for the methanogens is key.

Hydrogen Metabolism by Rhodomicrobium vannielii [PDF]
Journal of Bacteriology, 1969 Under appropriate cultural conditions, cell suspensions of Rhodomicrobium vannielii effect two distinct photoreactions involving molecular hydrogen: (i) the photoreduction of carbon dioxide, and (ii) the photoproduction of hydrogen.

Redirection of Metabolism for Biological Hydrogen Production [PDF]
Applied and Environmental Microbiology, 2007 ABSTRACT A major route for hydrogen production by purple photosynthetic bacteria is biological nitrogen fixation. Nitrogenases reduce atmospheric nitrogen to ammonia with the concomitant obligate production of molecular hydrogen.
