Identification and characterization of yeasts isolated from the South Shetland Islands and the Antarctic Peninsula
(Springer Verlag, 2017)
© 2016, Springer-Verlag Berlin Heidelberg. Antarctica is considered one of the most extreme environments on Earth because of its low temperatures, dryness, high incidence of solar radiation and low nutrient availability. ...
Diversity and extracellular enzymatic activities of yeasts isolated from King George Island, the sub-Antarctic region
(2012)
Background: Antarctica has been successfully colonized by microorganisms despite presenting adverse conditions for life such as low temperatures, high solar radiation, low nutrient availability and dryness. Although these ...
Evaluation of yeast derivative products developed as an alternative to lees: The effect on the polysaccharide, phenolic and volatile content, and colour and astringency of red wines
(MDPI AG, 2019)
Due to the increase of the use of yeast derivatives (YDs) in winemaking to improve the technological and sensory properties in wines, in this work we evaluated the effect of the post-fermentation application of different ...
Levedura íntegra e derivados do seu processamento em rações para tilápia do Nilo: Aspectos hematológicos e histológicos
(2006-10-01)
The effects of inclusion of whole yeast, autolyzed yeast and yeast cell wall on hematological parameters and gut villus perimeter were evaluated in juvenile Nile tilapia, after 80 experimental days. Isoproteic (32.0% DP) ...
The diversity of effects of yeast derivatives during sparkling wine aging
(Elsevier, 2022)
This study shows the monitoring of the physical, chemical and sensorial changes that occur in the sparkling wine along 18 months of aging due to different typology yeast-derived products; dry inactivated yeast from ...
Biotechnological Utilization of Biodiesel-Derived Glycerol for the Production of Ribonucleotides and Microbial Biomass
(HUMANA PRESS INCTOTOWA, 2012)
Ten yeast strains were evaluated concerning their capabilities to assimilate biodiesel-derived glycerol in batch cultivation. The influence of glycerol concentration, temperature, pH and yeast extract concentration on ...
Antagonistic interactions between garden yeasts and microfungal garden pathogens of leaf-cutting ants
(Springer, 2009-10-01)
We investigate the diversity of yeasts isolated in gardens of the leafcutter ant Atta texana. Repeated sampling of gardens from four nests over a 1-year time period showed that gardens contain a diverse assemblage of yeasts. ...
Technical note: Use of internal transcribed spacer for ruminal yeast identification in dairy cows
(Cambridge University Press, 2016)
Molecular techniques are important tools for microbiological studies in different habitats, and the internal transcribed spacer (ITS) has been proved to be useful for analyzing fungal diversity. The aim of this study was ...
Analysis of the Yeast Peptidome and Comparison with the Human Peptidome
(Public Library Science, 2016-09-29)
Peptides function as signaling molecules in species as diverse as humans and yeast. Mass spectrometry-based peptidomics techniques provide a relatively unbiased method to assess the peptidome of biological samples. In the ...
Distinct Domestication Trajectories in Top-Fermenting Beer Yeasts and Wine Yeasts
(Cell Press, 2016-10)
Beer is one of the oldest alcoholic beverages and is produced by the fermentation of sugars derived from starches present in cereal grains. Contrary to lager beers, made by bottom-fermenting strains of Saccharomyces ...
