The success of food and beverage production processes carried out by Saccharomyces
cerevisiae and the thriving of food spoilage fungi are dependent on the ability of a cell to
cope with the many environmental insults imposed during food production and preservation …

There has been a great deal of interest in fuel productions from lignocellulosic biomass to
minimize the conflict between food and fuel use. The bioconversion of xylose, which is the
second most abundant sugar present after glucose in lignocellulosic biomass, is important …

The emerging transdisciplinary field of Toxicogenomics aims to study the cell response to a
given toxicant at the genome, transcriptome, proteome and metabolome levels. This
approach is expected to provide earlier and more sensitive biomarkers of toxicological …

The optimization of industrial bioethanol production will depend on the rational design and
manipulation of industrial strains to improve their robustness against the many stress factors
affecting their performance during very high gravity (VHG) or lignocellulosic fermentations. In …

PhaR from Paracoccus denitrificans functions as a repressor or autoregulator of the
expression of genes encoding phasin protein (PhaP) and PhaR itself, both of which are
components of polyhydroxyalkanoate (PHA) granules (A. Maehara, S. Taguchi, T …

Wine fermentation is a harsh ecological niche to which wine yeast are well adapted. The
initial high osmotic pressure and acidity of grape juice is followed by nutrient depletion and
increasing concentrations of ethanol as the fermentation progresses. Yeast's adaptation to …

An optimal medium (300 g· L− 1 initial glucose) comprising 6.3 mmol· L− 1 Mg 2+, 5.0 mmol·
L− 1 Ca 2+, 15.0 g· L− 1 peptone and 21.5 g· L− 1 yeast extract was determined by uniform
design to improve very high gravity (VHG) ethanol fermentation, showing over 30% increase …

This work was designed to identify yeast cellular functions specifically affected by the stress
factors predominating during the early stages of wine fermentation, and genes required for
optimal growth under these conditions. The main experimental method was quantitative …

The presence of toxic compounds derived from biomass pre-treatment in fermentation media
represents an important drawback in second-generation bio-ethanol production technology
and overcoming this inhibitory effect is one of the fundamental challenges to its industrial …

Vacuolar H+‐ATPase (V‐ATPase) is thought to play a role in stress tolerance. In this study it
was found that bottom‐fermenting yeast strains, in which the V‐ATPase‐related genes
DBF2, VMA41/CYS4/NHS5 and RAV2 were overexpressed, exhibited stronger ethanol …
