Grape must harbors a complex community of yeast species responsible for spontaneous alcoholic fermentation. Although there are detailed studies on the microbiota of Vitis vinifera L. grapes, less is known about the diversity and behavior of yeast communities present on fermenting grape must from other species of Vitis. In this work, we used a culture-dependent method to study the identity and d...

Understanding the relationship between population genetic structure and phenotypic diversity is a fundamental question in evolutionary biology. Yeasts display wide exhibit remarkably diverse heterotrophic metabolisms that allow variety of niche occupations. However, little known about how intra-species related to trait yeasts. In this study, we investigated link floral nectar-inhabiting yeast M...

Lactose may affect the immune response mediated from the gut and interact with gastrointestinal microbiota; however no effects of milk-yeast on growth performance were detected. Summary An experiment was conducted to evaluate the effects of dietary lactose alone or in combination with dried milk-yeast product on growth performance , gastrointestinal microbiota, and immune parameters in weanling...

The complexity and dynamic nature of the “lipidome” of eukaryotic cells are increasingly apparent. Taking into account the diversity within many lipid classes created by variability in such factors as acyl chain substitutions, degree of desaturation, hydroxylation, and phosphorylation, the number of molecular species in eukaryotic cells exceeds one thousand. Such estimates of the diversity of t...

Climate, soil, and grape varieties are the primary characteristics of terroir and lead to the definition of various appellations of origin. However, the microbiota associated with grapes are also affected by these conditions and can leave a footprint in a wine that will be part of the characteristics of terroir. Thus, a description of the yeast microbiota within a vineyard is of interest not on...

conclusions our results demonstrated no significant correlation between the ird5 lifespan and the trehalose concentration. likewise, the correlation between lifespan extension, trehalose accumulation, and cellular resistance to hydrogen peroxide was not significant. results the lifespan of the ird5 mutant was significantly longer that of either the ird11 mutant or the wild type cells. under rep...
