“…At a weak acid condition (an initial pH of 5.5-6.5), hydrogen producing bacteria such as Clostridia species can be activated to extrude the express proton from cytoplasm to facilitate the resumption of the cell growth as well as producing hydrogen which normally exhibited at the exponential growth phase of this species (Jianlong & Wei 2009;Phowan & Danvirutai 2014). The results were consistent with the previous study which found that pH in the range of weak acid was an optimum pH for hydrogen production by anaerobic fermentative bacteria (Jianlong & Wei 2009;Phowan & Danvirutai 2014;Sivagurunathan et al 2016).…”

“…The results showed that the change in initial total sugar concentration remarkably affected the production of hydrogen. Although increase in total sugar concentration could enhance the hydrogen production, but the higher total sugar concentration also results in the accumulation of soluble metabolites product and a drop in pH which can inhibit the growth of microorganisms (Sivagurunathan et al 2016). In addition, the increase in total sugar concentration could increase the partial pressure of hydrogen in the headspace of reactor resulting in the inhibition of hydrogen production caused from the switching of hydrogen production pathway to solvent production pathway (Table 3) (Jianlong & Wei 2009;Sivagurunathan et al 2016).…”

“…HRT controls the organic loading rate (OLR), substrate degradation and reaction kinetics. The organic wastes required long HRT, whereas the simple organics required short HRT [2]. The reported optimum HRT value for the wastewater ranges from 0.5 to 24 h. For example, the short HRT (0.5 h) provided the maximum hydrogen production rate of 14 L/L-d from condensed soluble wastewater [27], whereas the long HRT (24 h) is required for eicient conversion of olive mill wastewater with a HPR of 7.0 L/L-d [28].…”

“…For example, the green algae/ cyanobacteria decomposes the water into gas (H 2 ) and liquid (H 2 O) in the presence of sunlight by photosynthesis pathway, whereas the slow growth of the algal cells and an inhibition of hydrogenase enzyme with the presence of traces of oxygen limit their application in large scale extent. The photosynthetic bacteria and dark fermentation bacteria share a similar metabolism for the breakdown of organic compounds for their energy and the liberation of energy [1,2]. The photosynthetic bacteria use organic acids as a substrate and prone to the ammonium and oxygen toxicity, making it as unsuitable for commercial hydrogen production.…”

Biohydrogen production technology is an emerging ield for the advanced wastewater treatment with cogeneration of energy. Besides, hydrogen is an excellent candidate with high energy value (122 kJ/g) than other known carbon-based fuels with no adverse efects to the environment as it releases only water vapor as the by-products during the combustion. Biohydrogen production technology can be assisted through two major pathways: (a) light-dependent reaction (biophotolysis and photofermentation) and (b) light-independent reaction (dark fermentation and microbial electrohydrogenesis cells). The light-dependent reaction can be catalyzed by photosynthetic bacteria, whereas the dark fermentation catalyzed by the heterotrophic bacterial group of facultative and obligate anaerobes. The wastewaters are a rich source of organic nutrients which supports the growth of hydrogen producers along with the disposal of waste and energy recovery. In the present chapter, the recent advancements on biohydrogen production technology from wastewaters with respect to the (a) inoculum development, (b) process optimization, (c) scale-up and (d) the challenges and perspectives toward the improvement of this emerging technology for the wastewater treatment.

“…In this context, producing clean energy carriers such as hydrogen (H2) from organic biomass has attracted the attention of environmental and energy scientists. H2 has a high energy content (142 MJ kg -1 ) and only water is produced during its combustion, making hydrogen a green and potential fuel for the future Sivagurunathan et al, 2016;Kumar et al, 2016a).…”

HIGHLIGHTSMixed microalgal biomass was evaluated for fermentative biohydrogen production.pH control at 5.5 was necessary for enhancement of production performances.Methanogenic inhibitor (BESA) addition enhanced hydrogen production by 3 folds. Hydrogen production from mixed microalgae biomass, predominantly containing Scendesmus and chlorella species, was investigated with a focus on enhancement strategies, in particular (i) pH control (at 5.5) and (ii) methanogenic inhibitor (BESA) addition along with pH control at 5.5. The results obtained showed that the later condition remarkably increased the performances. This was mainly ascribed to the occurrence of a suitable environment for the hydrogen producers to perform actively. Hydrogen production under these conditions (i.e., both pH 5.5 and pH 5.5+BESA) was significantly higher than that of the control experiment. Using the pH control at 5.5 and BESA addition, peak hydrogen production rate (HPR) and hydrogen yield (HY) were attained as 210 mL/L/d and 29.5 mL/g VSadded, respectively. This improvement was nearly 3-folds higher compared with the control experiment with an HPR of 62 mL/L/d and an HY of 9.5 mL/g VSadded. GRAPHICAL ABSTRACT ARTICLE INFO ABSTRACT
