“…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.

“…[13]; however some organisms of no utility (e.g. propionic acid and homoacetogenic bacteria) may also survive and reclaim their niche over time [21,25]. Changes in the microbial background can be revealed by the modern technical apparatus of molecular biology [32,33].…”

“…Both groups were repeatedly experimentally confirmed as major hydrogen producers (Valdez-Vazquez & Poggi-Varaldo, 2009 Enteric bacteria are gram-negative rods, facultative aerobic, with relatively simple nutrient requirements and can not form spores (Schmauder, 1992). Among the species that can produce H2, are Escherichia (E. coli), Proteus (P. vulgaris), Enterobacter (E. aerogenes).…”

“…Biohydrogen production is associated with the activities of hydrogenase and NAD + / NADH, both of which favor low oxidation-reduction potential (ORP) environment [20]. As a unique natural amino acid, L-cysteine contains a thiol group that can form disulfide bond.…”

This study investigated the anaerobic hydrogen production from cassava residues using the mixed culture from giant panda (Ailuropoda melanoleuca) excrement. The FTIR and XRD results demonstrated that cassava residues could be degraded by the anaerobic mixed culture from grand panda excrement, and that maximum H 2 production rate (R max ) and the maximum cumulative H 2 production (H max ) and were 152.86 mL·L -1 ·h -1 and 688.36 mL·L -1 respectively in the dark fermentation. The effects of L-cysteine on H 2 production, substrate utilization, metabolites distribution and biomass were studied in batch-mode tests. The results showed that the cassava residues were degraded by 31.6% through H 2 production. After adding L-cysteine (0.5-2.0 g·L -1 ) to the nutrient solution, the biomass concentration reached to 1.53 g·L -1 , about 1.36 times higher than that of the control group without L-cysteine addition, and the dark fermentative H 2 production was 1.6-2.0 times higher than that of the control group. Our results demonstrated that by using the anaerobic mixed culture from giant panda excrement, cassava residues could be converted into H 2 efficiently with the addition of L-cysteine during the dark fermentation.
