Production of biofuels by thermoanaerobic bacteria

Ed van Niel, Johann Örlygsson

Research output: Chapter in Book/Report/Conference proceedingBook chapterResearchpeer-review


Biofuel demand is gradually rising yearly and is expected to do so more rapidly due to the current energy crisis. Bioethanol production is already at a commercial scale but is primarily made using mesophiles fermenting corn and sugar, which have obvious societal drawbacks. Therefore, new technologies should be developed. In addition, hydrogen as a non-carbon energy carrier has gained renewed interest. Thermophilic hydrogen and ethanol production from lignocellulosics and organic wastes, therefore, provide new avenues of biofuel production. This overview looks concisely into the status and remaining challenges of hydrogen and ethanol production exploiting thermophilic anaerobic bacteria.
