“…Among them, bioreactor configuration and operation are apparent ones [10]. Regardless the type of the fermenter, it can be concluded that feasible biohydrogen fermentation should be conducted in continuous rather than batch systems [11], e.g. due to higher expectable process efficiencies.…”

a b s t r a c tThe start-up of continuous biohydrogen fermentations is a complex procedure and a key to acceptable hydrogen production performance and successful long-term operation. In this review article, the experiences gained and lessons learned from relevant literature studies dealing with various aspects of H 2 producing bioreactor start-up are comprehensively surveyed. Firstly, the importance of H 2 -forming biosystem start-up including its main steps is outlined. Afterwards, the role of main influencing factors and methods (e.g. strain selection, seed pretreatment and inocula stimulation, switch-over time, bioreactor design, operating conditions) in avoiding the deterioration of starting a reactor is analyzed and presented in detail. Finally, the so far suggested applicable start-up strategies and the corresponding findings are critically discussed pointing out the advantages and disadvantages of each strategy.

“…Degradation of biowastes to methane (CH 4 ) and carbon dioxide is a multiple step process with possibilities to produce H 2 and bioplastics (from volatile fatty acids) as intermediates [1,5]. The whole process is becoming attractive on account of higher production efficiency, stability and economic feasibility [6].…”

“…H 2 process is influenced by pH of the growth medium, which may vary from 4.5 to 9.0 [6]. Bacteria such as, Bacillus licheniformis, Clostridium pasteurianum, Enterobacter cloacae and Rhodobacter sphaeroides were found to be produce H 2 in the range of 6.5-7.5.…”

Metabolic activities of four Bacillus strains to transform glucose into hydrogen (H 2 ) and polyhydroxybutyrate (PHB) in two stages were investigated in this study. Under batch culture conditions, Bacillus thuringiensis EGU45 and Bacillus cereus EGU44 evolved 1.67-1.92 mol H 2 /mol glucose, respectively during the initial 3 days of incubation at 37°C. In the next 2 days, the residual glucose solutions along with B. thuringiensis EGU45 shaken at 200 rpm was found to produce PHB yield of 11.3% of dry cell mass. This is the first report among the non-photosynthetic microbes, where the Bacillus spp.-B. thuringiensis and B. cereus strains have been shown to produce H 2 and PHB in same medium under different conditions.

“…Hydrogen (H 2 ) is considered as a suitable alternative source of energy owing to its regenerative, carbon neutral and high energy yielding (122 kJ/g) property (Kapdan and Kargi 2006;Brown et al 2007;Balat 2008;Das and Veziroglu 2008;Wang and Wan 2009;Suleman et al 2015). However, presently about 96% of H 2 are produced from fossil fuels, which are again energy intensive, economically and environmentally not feasible (Momirlan and Veziroglu 2002;Nath and Das 2004;Ewan and Allen 2005;Mohanty et al 2015).…”

Hydrogen (H 2 ) produced from biological methods is a potential option to meet the growing clean energy needs. The present study aimed to produce biohydrogen by dark fermentation from nuisance aquatic weed, Eichhornia crassipes, using facultative anaerobic bacteria. A total of 12 bacterial strains were isolated from different wastewater sources and were screened for the potential of H 2 production using glucose as carbon source. Ten strains showed the H 2 -producing potential and were identified up to the generic level by biochemical tests. Two strains with higher H 2 production were sequenced using PCR technique and identified as Proteus mirabilis and Pseudomonas aeruginosa and selected for the studies with E. crassipes as the substrate. It was found that P. aeruginosa could produce 19.54 ± 0.03% of H 2 from 2% acid (H 2 SO 4 ) treated substrate which was comparatively higher than that of 4 and 8% treatments. P. mirabilis also yielded better results of 5.42 ± 0.02% H 2 f or 2% acid (H 2 SO 4 ) treated substrate than 4 and 8% treatments. In total, 33.52 ± 0.04% of H 2 was produced by P. aeruginosa for the substrate treated with 2% alkali (NaOH). It was noted that with respect to P. mirabilis 4% alkali treated substrate yielded a higher percentage of H 2 (20.23 ± 0.03%) compared to the other two concentrations. The results indicate that alkali treated substrate produced comparatively higher amount of H 2 than that of acid treated substrates. Regarding efficiency, P. aeruginosa was found to be more competent than P. mirabilis.
