Biohydrogen production and bioprocess enhancement: A review

Abstract

This paper provides an overview of the recent advances and trends in research in the biological production of hydrogen (biohydrogen). Hydrogen from both fossil and renewable biomass resources is a sustainable source of energy that is not limited and of different applications. The most commonly used techniques of biohydrogen production, including direct biophotolysis, indirect biophotolysis, photo-fermentation and dark-fermentation, conventional or "modern" techniques are examined in this review. The main limitations inherent to biochemical reactions for hydrogen production and design are the constraints in reactor configuration which influence biohydrogen production, and these have been identified. Thereafter, physical pretreatments, modifications in the design of reactors, and biochemical and genetic manipulation techniques that are being developed to enhance the overall rates and yields of biohydrogen generation are revisited.

Hydrogen production by Escherichia coli during glucose fermentation: Effects of oxidative and reductive routes used by the strain lacking hydrogen oxidizing hydrogenases 1 (hya) and 2 (hyb)

“…The possible use of microorganisms for production of molecular hydrogen (H 2 ) as a future ecologically clean, renewable and effective energy source [1,2] makes H 2 metabolism a promising field of research. Many microorganisms can produce H 2 by reactions linked to their energy metabolism: the bacterium Escherichia coli is among H 2 producing bacteria performing mixed-acid fermentation of sugars (glucose) or glycerol [3].…”

Immobilization of Enterobacter aerogenes by a Trimeric Autotransporter Adhesin, AtaA, and Its Application to Biohydrogen Production

“…Biological hydrogen production promises a less energy intensive and more environmentally friendly process than traditional processes [1,2]. Most bioprocesses occur at ambient temperatures and pressures.…”

Energy recovery through biohydrogen production for sustainable anaerobic waste treatment: an overview

“…Using anaerobic mixed culture to treat wastewater and produce H 2 is challenged by limitations in biochemical reactions and metabolic pathways performed by H 2 producing microorganisms, reactor design and process configuration, as well as H 2 consuming microorganisms and reactions which influence H 2 production rate and yield (Mudhoo et al, 2011). Therefore, energy and nutrients recovery enhances the sustainability of waste treatment methods.…”
