“…In the metal center of a [NiFe] type hydrogenase, the active site usually contains two cis nickel (Ni) coordination sites available for substrate binding, a bridging site and a terminal Ni site, with the Ni site terminally bound to the thiolate of Cysteine 530 [30]. [NiFe] widely exists in bacteria during hydrogen fermentation, while the [FeFe]-type hydrogenase can only be found in a few microbial species, such as green algea Chlamydomonas reinhardtii [31,32].…”

Bio-hydrogen production (BHP) produced from renewable bio-resources is an attractive route for green energy production, due to its compelling advantages of relative high efficiency, cost-effectiveness, and lower ecological impact. This study reviewed different BHP pathways, and the most important enzymes involved in these pathways, to identify technological gaps and effective approaches for process intensification in industrial applications. Among the various approaches reviewed in this study, a particular focus was set on the latest methods of chemicals/metal addition for improving hydrogen generation during dark fermentation (DF) processes; the up-to-date findings of different chemicals/metal addition methods have been quantitatively evaluated and thoroughly compared in this paper. A new efficiency evaluation criterion is also proposed, allowing different BHP processes to be compared with greater simplicity and validity.

“…Moreover, the [NiFe] hydrogenases are common among the fermentative bacteria, whereas the [FeFe] hydrogenases are only restricted to a few species of bacteria. Therefore, targeting the improvement of the activity of [NiFe] hydrogenase will be a practical approach for the enhancement of hydrogen production . Nonetheless, the numbers of the works of investigating the effects of adding BC together with the nickel particles and their combined effects are still limited .…”

Summary The improvement of hydrogen production was achieved by the addition of biochar (BC) and metal co‐factor nanoparticle Ni0 during the dark fermentation. A new hybrid approach by combing the artificial neural networks with the response surface methodology was applied to optimize the hydrogen production. The effects of operating conditions, ie, BC, metal cofactor Ni0, pH, and dosage of microbes, upon the hydrogen production together with the concentrations of other metabolites such as the acetic acid, propionic acid, butyric acid, and ethanol were extensively investigated. From kinetic study of the major metabolites, the acetate pathway was found to be apparently enhanced by the addition of synergistic factors. The modified anaerobic digestion model with the consideration of inhabitation factor was found to best represent the kinetics of hydrogen production and the formation of major metabolites.

“…The significant developments in the area of nanotechnology accelerating have improved their potential applications in improving the biological processes. This has been specially aided by the availability of nanostructured materials-nanoparticles (NPs), which have suitable physical and chemical properties [19][20][21][22][23][24]. The bioprocess for generating H 2 by microorganisms occurs through either disposal of excess reducing equivalents or as nitrogen fixation byproduct [25].…”

Biological hydrogen (H) production enhancement through the use of nanoparticles (NPs) supplement in the media is being recognized as a promising approach. The NPs, including those of metal and metal oxides have shown a significant improvement in the BHP. A number of organisms as pure or mixed cultures can produce H in presence of NPs from pure sugars and biowaste as a feed. However, their H production efficiencies have been found to vary significantly with the type of NPs and their concentration. In this review article, the potential role of NPs in the enhancement of H production has been assessed in dark- and photo-fermentative organisms using sugars and biowaste materials as feed. Further, the integrative approaches for commercial applications of NPs in BHP have been discussed.
