“…Fermentative biohydrogen generation can be realized either by pure cultures [18] such as Escherichia coli [19,20] or mixed bacterial consortia [21,22] and both have their own benefits. For example, cultures of pure isolates may be easier to control but need constantly sterile environment to prevent contamination that is difficult and costly to maintain out of laboratories.…”

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.

“…Consequently, the bioaugmentation of heat-treated sludge with facultative anaerobic strains might result in the improvement of hydrogen production. Moreover, in studies when their pure cultures were used some significant achievements have been published, however, mostly with simple substrates [8].…”

In this work biohydrogen generation and its improvement possibilities from beverage industrial wastewater were sought. Firstly, mesophilic hydrogen fermentations were conducted in batch vials by applying heat-treated (80 o C, 30 min) sludge and liquid (LB-grown) cultures of Escherichia coli (XL1-Blue)/Enterobacter cloacae (DSM 16657) strains for bioaugmentation purposes. The results showed that there was a remarkable increase in hydrogen production capacities when facultative anaerobes were added in the form of inoculum. Furthermore, experiments were carried out in order to reveal whether the increment occurred either due to the efficient contribution of the facultative anaerobic microorganisms or the culture ingredients (in particular yeast extract and tryptone) supplied when the bacterial suspensions (LB media-based inocula) were mixed with the sludge. The outcome of these tests was that both the applied nitrogen sources and the bacteria (E. coli) could individually enhance hydrogen formation.Nevertheless, the highest increase took place when they were used together. Finally, the optimal initial wastewater concentration was determined as 5 g/L.

“…Biohydrogen can be obtained by dark fermentation of carbohydrates under both thermophilic and mesophilic conditions, and the exploitation of this process for the production of an environmentally friendly energy source could also reduce the dependence on fossil fuels [1].…”

Background: Sustainable biohydrogen production can be achieved by dark fermentation of organic wastes, and studies were carried out using a range of substrates and inocula. The bacterial populations involved were mainly identified as facultative anaerobes (Enterobacteriaceae) and strictly anaerobes (Clostridiales), and their dynamics in relation to H 2 and metabolite production depends on the physical and environmental conditions of the bioreactor. This study has evaluated the use of length heterogeneity (LH)-PCR fingerprinting to detect changes in the microbial community during continuous hydrogen production under dark fermentation.
