Relatively large percentages of xylose with glucose, arabinose, mannose, galactose and rhamnose constitute the … mannose and galactose were more effective for hydrogen production than those of xylose and arabinose. The substrate of 5g …/l xylose resulted in a relative high level of hydrogen yield (73.8mmol/l), hydrogen production efficiency (2.2mol/mol) and a …

energy of xylose in the degrading reaction was obtained. The kinetic equations that correlated the effect of hydrogen ion … one way to produce fermentable saccharide. In this process, the yield of xylose is always low because of the degrading … during the acid environment. In this paper, the degrading kinetics of xylose in the hydrolysate was investigated under the …

Biohydrogen production from xylose by Thermotoga neapolitana was investigated in batch culture using serum bottles and … a continuously stirred anaerobic bioreactor (CSABR). The effect of various xylose concentrations on growth and H2 … production were studied in small batch culture for highly efficient H2 production. The highest hydrogen production of 32 …

The xylose conversion to ethanol by Pichia stipitis was studied. In a first step, the necessity of supplementing the … fermentation medium with urea, MgSO4 × 7H2O, and/or yeast extract was evaluated through a 23 full factorial design. The … simultaneous addition of these three nutritional sources to the fermentation medium, in concentrations of 2.3, 1.0, and 3.0 g …

Xylose and xylooligomers are the main five-carbon sugar in the hot water extract, which reached …, mannose, rhamnose, glucose, and arabinose are also obtained during the hot water extraction. Rhamnose is the main six … found to be adequate in describing the dissolved solids, acids, xylose, and xylooligomers. …
