Efficient and rapid fermentation of all sugars present in cellulosic hydrolysates is essential
for economic conversion of renewable biomass into fuels and chemicals. Xylose is one of …

The lack of microbial strains capable of fermenting all sugars prevalent in plant cell wall
hydrolyzates to ethanol is a major challenge. Although naturally existing or engineered …

The isomerization of xylose to xylulose is considered the most promising approach to initiate
xylose bioconversion. Here, phylogeny-guided big data mining, rational modification, and …

Background The production of bioethanol from lignocellulose hydrolysates requires a
robust, D-xylose-fermenting and inhibitor-tolerant microorganism as catalyst. The purpose of …

Background Xylose isomerase (XI) and xylose reductase/xylitol dehydrogenase (XR/XDH)
pathways have been extensively used to confer xylose assimilation capacity to …

Background Predictable control of gene expression is necessary for the rational design and
optimization of cell factories. In the yeast Saccharomyces cerevisiae, the promoter is one of …

Economic bioconversion of plant cell wall hydrolysates into fuels and chemicals has been
hampered mainly due to the inability of microorganisms to efficiently co-ferment pentose and …

The biorefinery concept, consisting in using renewable biomass with economical and
energy goals, appeared in response to the ongoing exhaustion of fossil reserves. Bioethanol …

Exploration of yeast diversity for the sustainable production of biofuels, in particular
biodiesel, is gaining momentum in recent years. However, sustainable, and economically …

The rapid co-fermentation of both glucose and xylose is important for the efficient conversion
of lignocellulose biomass into fuels and chemicals. Saccharomyces cerevisiae is considered …
