“…During careful continuous adaptation, broth is constantly supplemented and such disadvantageous phenomenon may be avoided. Moreover, continuous (hydraulic detention time influenced) acclimatization strategy encompasses the so-called biokinetic control which causes the 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 wash out of existing microbes possessing inadequately low growth rates or adaption capabilities [42].

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.

“…Dark fermentation is a biological process where hydrogen is produced with concomitant liquid effluent treatment by reducing its organic load (Dincer, 2012). Glucose has been typically used as model substrate for hydrogen production by dark fermentation (Tapia-Venegas et al, 2013;Wang and Wan, 2008). However, a more economical source of carbon is preferable to avoid the use of Comment citer ce document : Silva-Illanes, F., Tapia-Venegas, E. (Auteur de correspondance), Schiappacasse, M.

Hydrogen is a promising alternative of clean energy carrier which can be biologically produced from glycerol-rich waste an abundant and economic source of substrate. However, continuous hydrogen-producing systems still need to be improved and in particular by manipulating the only few available operating conditions. The aim of this study was to investigate the effect of the two main operational parameters, ie. pH and hydraulic retention time (HRT) on hydrogen yields and microbial community structures. For that, a continuous stirred tank reactor (CSTR) was first inoculated with an enriched mixed microflora and was then fed with glycerol. A strong influence of these two operational parameters was shown on hydrogen yields where the maximum yield (0.58 ± 0.13 mol H2 mol-1 glycerol) was achieved at pH 5.5-HRT 12 h and was 28.5 times higher than the minimum (0.02 ± 0.02 mol H2 mol-1 glycerol) obtained at pH 5.0-HRT 14 h. Changes in most dominant microbial populations were mainly influenced by the pH. Interestingly, HRT parameter related to changes in the metabolic patterns and influenced the composition of subdominant Version postprint

“…33 Moreover, in this study, the accumulation of VFA production altered and rendered the micro-environment unfavorable for the growth of hydrogen-producing microbes, mainly responsible for the gap (Fig. 4); Tapia-Venegas et al 34 achieved a higher H o /H p value of about 61-80% accompanied by a lower VFA production (lower 5 mg L À1 ).…”
