Enzymatic production of biohydrogen

Nature, 2000
Although in theory the amount of hydrogen that could be generated from renewable sources of energy such as cellulose (a polymer of glucose) is vast1, only 16–24% of the maximum stoichiometric yield of hydrogen from glucose (about 12 mol H2 per mol glucose) is typically achieved by biological methods2.

Recent advances in biohydrogen research

Pflügers Archiv - European Journal of Physiology, 2000
A fundamental and principal difficulty of the future energy supply is that the formation of fossil fuels is much slower than the rate of their exploitation. Therefore the reserves which can be recovered in an energetically feasible manner are shrinking parallel with an increasing world-wide energy demand. Among the alternative energy carriers, hydrogen

Biohydrogenation in germ-free rats

Journal of Atherosclerosis Research, 1963
Summary [1-14C]-Elaidic acid was fed to 5 germ-free rats and 2 control rats. Percent distribution of radioactivity determined by degradation of stearic acid isolated from liver lipids of germ-free animals clearly showed that biohydrogenation of elaidic acid to stearic acid occurred in the germ-free rats.

The Science of Biohydrogen

2007
The importance of biological solar energy conversion to hydrogen is discussed from the viewpoint of energy and entropy. The historical view of the nature of the present system clarifies its limitations and the necessity for a brand-new energy accumulation technology, replacing the Industrial Revolution-based one.

The Technology of Biohydrogen

2007
Hydrogen produced by microalgae and bacteria is biohydrogen. There are currently no practical biohydrogen production processes. However, several concepts have promise for near- to long-term process development.
