Journal ArticleDOI
The effect of water-soluble inhibitors from steam-pretreated willow on enzymatic hydrolysis and ethanol fermentation
TL;DR: In this paper, the inhibitory effects of the accumulation of volatile and nonvolatile compounds released during stream pretreatment on enzymatic hydrolysis and fermentation were studied and it was shown that the volatile compounds did not affect either the enzyme or fermentation significantly even at high concentrations.
Journal ArticleDOI
Biochemistry and physiology of xylose fermentation by yeasts
TL;DR: The redox imbalance in the initial conversion of xylose to xylulose, sensitivity to high concentraions of ethanol, differences in the respiratory pathway and sensitivity to microbial inhibitors, have been identified as major factors limiting ethanol fermentation by the xylOSE-fermenting yeasts.
Journal ArticleDOI
Reduced oxidative pentose phosphate pathway flux in recombinant xylose-utilizing Saccharomyces cerevisiae strains improves the ethanol yield from xylose.
TL;DR: Results indicate that xylitol production is strongly connected to the flux through the oxidative part of the pentose phosphate pathway, leading to a lower rate of xylose consumption.
Journal ArticleDOI
Fermentative performance of bacteria and yeasts in lignocellulose hydrolysates
TL;DR: The sugar consumption rates and the product formation of yeasts and bacteria and S. cerevisiae emerged as one of the better candidates, owing to its fast sugar consumption rate and efficient ethanol production, for genetic engineering approaches.
Journal ArticleDOI
Effect of Oxygenation on Xylose Fermentation by Pichia stipitis.
TL;DR: The ratio of the xylose uptake rate under aerobic conditions, in contrast to that under anaerobic assay conditions, increased with increasing oxygenation in the culture and the results are discussed in relation to the energy level in the cell, the redox balance, and the mitochondrial function.
