Effect of cultivation temperature on fermentative hydrogen production from xylose by a mixed culture

Effect of fermentation temperature on hydrogen production from xylose and the succession of hydrogen‐producing microflora

“…Anaerobic hydrogen production has been reported over a wide temperature range due to the various microbial communities in the mixed culture. Different substrate metabolic pathways and microbial community structures have been observed at various temperatures . However, most studies were carried out over a small temperature range; the shift of xylose metabolic pathway and succession of microflora community over a wide temperature range, including mesophilic, thermophilic and extreme thermophilic conditions, has not been reported to our knowledge.…”

Ethanol and Hydrogen Production with Thermophilic Bactera from Sugars and Complex Biomass

“…compost, hot springs, manure or anaerobic digestion systems (Calli et al, 2008;Hniman et al, 2010;Karadag et al, 2009;Karadag & Puhakka, 2010;Lin et al, 2008;Zhao et al, 2009;Zhao et al, 2010). Available data from such experiments are presented in Table 4.…”

Hydrogen production using biocathode single-chamber microbial electrolysis cells fed by molasses wastewater at low temperature

“…For instance, the molasses wastewater is suitable for producing hydrogen via dark-fermentation processes [4,5]. However, since dark hydrogen fermentation often requires need mesophilic (30e40 C) [6,7] or thermophilic (50e80 C) conditions [8e10], it may not be practical in field applications in the high latitude region (such as Harbin city, China with an annual average temperature lower than 10 C) due to the cost of heating. Therefore, for the practical application of H 2 recovery from molasses wastewater in this area, the operating temperature should be reduced.…”
