Ethanol inhibition of continuous anaerobic yeast growth
… inhibitory effects of the product ethanol on the yeast Saccharomy cescerevisiae ATCC 4126 have been studied during the conversion of the substrate glucose. Continuous culture techniques under anaerobic conditions (the medium was not deaerated) were used where high concentrations of ethanol were …

The relationship of glycolytic/gluconeogenic intermediates in brewing yeast (Saccharomyces uvarum) fermentations to growth
… the metabolic interrelationship between yeast growth, regulation of glycolytic/gluconeogenic flux and accumulation of glycosyl donors for polysaccharide synthesis in brewing yeast (Saccharomyces uvarum) fermentations. Loss of fermenting power of a brewing yeast population may be created …

Sodium phosphate inhibition of the growth of selected foodborne spoilage yeasts
Sodium phosphite was evaluated for inhibition of growth of spoilage yeasts in laboratory media and in two commercial carbonated beverages. In addition, the effects of pH and atmosphere in combination with sodium phosphite were also examined in laboratory media. Inhibition studies in laboratory …

Application and Characterization of Bioactive Compounds in Peanut Skins, a Waste Product of Virginia Agriculture
… found to be inhibitory towards three types of yeasts (Saccharomyces cerevisiae, Zygosaccharomyces bailli, and Zygosaccharomyces bisporus). All extracts were devoid of solvents that may have interfered with the results. The OPC extract exhibited the highest inhibitory effect, and was chosen for …

Biodiesel production from coconut oil
… from the enzyme process as a carbon source for yeast growth resulted in improved kinetics to that for yeast growth on pure glycerol indicating that no inhibitory by-products were produced during the enzyme process. The overall economics of the process, and its sensitivity to key process …

Characterizing CMT-causing variants in tryptophanyl- tRNA synthetase
… in these enzymes. I created a humanized yeast model to assess the underlying disease-causing mechanism associated with two CMT variants, H257R and D314G, present in the human tryptophanyl-tRNA synthetase (WARS1). Using proteomic analysis, protein biochemistry, and yeast growth assays, I …

Susceptibility Testing of Pathogenic Fungi With a Radiometric System
… grown on SAB-DEX agar at 25°C and converted to yeast phase in a chemically defined, liquid medium at 37°C. Yeast inoculum was adjusted to 5x10⁴ cells. Results indicate that the radiometric method provides a reproducible, rapid, and quantitative measurement of the inhibitory effects of antifungal …

Defining the ethanol-stress response in Saccharomyces cerevisiae
Industrial yeast performance is often compromised during alcoholic fermentations due to bi-product inhibition. Ethanol is arguably the product with the greatest impact on yeast performance, acting as a potent chemical stress on yeast cells. This stress eventually inhibits yeast growth and reduces …

BIODIESEL PRODUCTION THROUGH MICROWAVE ASSISTED TRANSESTERIFICATION OF MICROBIAL CELLS
One strain of oleaginous yeasts, <italic>Cryptococcus curvatus</italic> (ATCC 20509) has been studied to grow on several substrates including biodiesel production byproduct crude glycerol and sweet sorghum juice. After cultivation, yeast cells were heated under microwave radiation to extract lipid …

Cellular subversion: towards a complete repertoire of type-III secretion system effectors in enterohaemorrhagic Escherichia coli O157:H7
… then investigated using mammalian cells and a yeast cell model. The effector EspM2 was shown to induce the formation of actin stress fibres in transfected HeLa cells and caused growth retardation when expressed in yeast. A number of NleG effectors also caused growth retardation and …

Evaluating the Fungistatic and Fungicidal Activities of Bianthrones as Synthetic Intermediates to Novel Hypericin Analogues.
… type derivatives and the effect they have on the growth of the yeast species Schizosaccharomyces pombe, Lipomyces starkeyi andSaccharomyces cerevisiae. It is hoped that a new antifungal agent could be identified to combat the threat of these resistant fungi in order to treat patients who have …

Modest Differences in Juice Yeast Assimilable Nitrogen Concentration and Composition Influence Wine Chemistry and Impart Limited Sensory Differences in Virginia-grown Chardonel
Nitrogen is requisite for yeast growth and metabolism during wine fermentation, and contributes to wine flavor development. Understanding how yeast assimilable nitrogen (YAN) impacts wine chemistry and sensory properties helps inform nitrogen management decisions in both the vineyard and winery. …

Haemophilus influenzae as a chassis for directed endosymbiosis
… supplemented with NAD and hemin supports the growth of both species, whereas synthetic complete yeast medium requires yeast extract or peptone to support H. influenzae. H. influenzae also rescued the adenine-linked red phenotype of S. cerevisiae VL6-48 and promoted yeast growth under …

Functional Characterization of the Mammalian TRPV4 Channel: Yeast Screen Reveals Gain-of-Function Mutations
… of TRP channels by their ability to rescue growth deficiency of a strain of the yeast Saccharomyces cerevisiae caused by lack of ion efflux. Channels were further characterized through electrophysiological analysis of their activity when heterologously expressed in Xenopus laevis oocytes. Of …

Characterization of Mitochondrially Targeted T3SS2 Effectors in Vibrio parahaemolyticus
… oxygen consumption rates and inhibited yeast growth. This growth phenotype was exacerbated by forcing the cells to use mitochondrial respiration for energy production. Metabolic analysis of the yeast expressing VPA1328 showed increases in fumarate, dihydroorotate, N-acetylputrescine, …

Histone Post-translational Modification Dysregulation Contributes to Toxicity in Amyotrophic Lateral Sclerosis Proteinopathy Models
… overexpression of the ALS-linked protein FUS in yeast is associated with a strong growth suppression phenotype and decreases in histone acetylation, phosphorylation and methylation. Furthermore, we show that treating these yeast with the Histone Deacetylase inhibitor Trichostatin A improves yeast …

Interaction of zinc with the yeast <i>Saccharomyces cerevisiae</i>
… the influence of zinc on cell physiology of the yeast Saccharomyces cerevisiae. Zinc uptake by industrial strains of S. cerevisiae, including brewing strains, and the subsequent utilisation of this key metal during fermentation was studied. Yeast strains take up most of the available zinc very …
