“…This would be more practical when waste or wastewater at high temperature was used as substrate . Hydrogen yield (0.45 mol H 2 mol −1 xylose consumed ) gained at extreme thermophilic temperature (65°C) was incomparable with that gained in previous reports . Despite the different substrates or xylose concentration used in previous studies, low hydrogen production efficiency was observed in this study.…”

“…Although, with lower hydrogen yield at 60°C (1.04 mol H 2 mol −1 xylose consumed ), heat pretreatment was not needed to inhibit methane‐producing bacteria during repeated batch culture at 60°C and at 65°C. This would be more practical when waste or wastewater at high temperature was used as substrate . Hydrogen yield (0.45 mol H 2 mol −1 xylose consumed ) gained at extreme thermophilic temperature (65°C) was incomparable with that gained in previous reports .…”

BACKGROUND Hydrogen production through anaerobic dark fermentation is considered to be a potential biological process for xylose utilization. Temperature is one of the most important environmental factors, however, most studies have been carried out over a small temperature range. Batch tests were carried out to investigate the temperature effect on hydrogen production from xylose using a mixed culture over a wide temperature range (35–65°C). Hydrogen production, metabolite distribution and dynamics of microbial communities were investigated. RESULTS Hydrogen‐producing cultures were successfully enriched at each tested temperature. Two peaks of fermentation temperature for hydrogen production were observed at 35 and 55°C (1.11 and 1.30 mol‐H2 mol−1‐xyloseconsumed, respectively). Butyrate and acetate were the major liquid metabolites at 35–60°C. While at 65°C the main by‐product was ethanol. Polymerase chain reaction‐denaturing gradient gel electrophoresis (PCR‐DGGE) analysis indicated that Clostridium species were dominant at 35–40°C, while Thermoanaerobacterium dominated at 45–60°C. Both species were found at 65°C, but with lowest microbial community diversity. CONCLUSION Hydrogen production efficiency was mainly affected by the liquid metabolite distributions, which depended mainly upon the temperature. Several microbial community structures were formed at mesophilic, transition, thermophilic and extreme‐thermophilic conditions, resulting in different metabolic pathways of xylose and hydrogen production capacity. © 2017 Society of Chemical Industry

“…Biohydrogen is an ideal, clean and friendly energy source that does not produce environmental pollution as carbon dioxide [3]. Furthermore, it can be produced from various renewable resources, which might be derived from pure sugars (glucose and xylose) [4,5], agricultural residues, woody biomass [6][7][8] and biodiesel industry (glycerol waste) [9,10], via biological conversion. Therefore, fermentative biohydrogen production technology has developed rapidly and considered as a promising treatment technology for organic wastes with efficient clean bioenergy production [11,12].…”

Biohydrogen fermentation using immobilized cells of Thermotoga neapolitana on porous glass beads was successfully performed in a continuously stirring anaerobic bioreactor (CSABR) system operated under the conditions of temperature 75 o C, pH 7.0 and 5.0 g/L pentose (xylose) and/or hexose (glucose). The results showed that both batch and fed-batch cultivations of the immobilized cells were effective for high-rate and high-yield H2 production compared with those from the free cells. In the batch cultivation, the H2 production rate and H2 production yield of the immobilized cells, respectively achieved the highest values of 5.64 ± 0.19 mmol-H2 L -1 h -1 and 1.84 ± 0.1 mol H2/mol xylose, which were almost 1.7-fold and 1.3-fold higher than those with free cells. The maximum H2 production rate (6.91 mmol L -1 h -1 ) in this proposed method was 1.5-fold higher than that of free cells in the fed-batch cultivation.
