Analysis of Saccharomyces cerevisiae deletion mutants displaying a modified carbon flux under wine fermentative conditions

Madlanga, Ncedile Hamilton (Stellenbosch : University of Stellenbosch, 2009-03)

Saccharomyces cerevisiae has been used for millennia for the leavening of dough and in the production of alcoholic beverages such as beer and wine. More recently, it is being used as cell factories for the production of ...
Carnitine metabolism and biosynthesis in the yeast Saccharomyces cerevisiae

Franken, Jaco (Stellenbosch : University of Stellenbosch, 2009-12)

ENGLISH ABSTRACT: Carnitine plays an essential role in eukaryotic metabolism by mediating the shuttling of activated acyl residues between intracellular compartments. This function of carnitine, referred to as the carnitine ...
Characterization and evaluation of glucose oxidase activity in recombinant Saccharomyces cerevisiae strains

Malherbe, Daniel Francois (Stellenbosch : Stellenbosch University, 2010-03)

ENGLISH ABSTRACT: Popular wine styles prepared from fully-ripened, more mature grapes are characterized by intense fruitiness and varietal flavors. However, lengthy maturation of grapes in the vineyard does not only ...
Industrial yeast strains engineered for controlled flocculation

Govender, Patrick (Stellenbosch : University of Stellenbosch, 2009)

In many industrial fermentation processes, Saccharomyces cerevisiae yeast should ideally meet two partially conflicting demands. During fermentation a high suspended yeast count is of paramount importance to maintain a ...
Many saccharomyces cerevisiae cell wall protein encoding genes are coregulated by Mss11, but cellular adhesion phenotypes appear only flo protein dependent

Bester, Michael C. Jacobson, Dan Bauer, Florian F. (Genetics Society of America, 2012-01)

The outer cell wall of the yeast Saccharomyces cerevisiae serves as the interface with the surrounding environment and directly affects cell2cell and cell2surface interactions. Many of these interactions are facilitated ...
Modifying redox potential and its impact on metabolic fluxes in Saccharomyces cerevisiae

Jain, Vishist Kumar (Stellenbosch : University of Stellenbosch, 2010-03)

ENGLISH ABSTRACT: The production of glycerol by Saccharomyces cerevisiae under anaerobic conditions is essential for maintaining the intracellular redox balance thereby allowing continuous energy generation through ...
Optimization of β-glucosidase activy in recombinant Saccharomyces cerevisiae strains

Ranwedzi, Ntanganedzeni (Stellenbosch : Stellenbosch University, 2007-12)

ENGLISH ABSTRACT: Wine is a complex medium. Wine aroma, flavour and colour are important quality factors, but these can be influenced by many factors, such as grape-derived compounds that exist as free volatiles and also ...
Winemaking practices affecting glutathione concentrations in white wine

Kritzinger, Engela Cornelia (Stellenbosch: Stellenbosch University, 2012-03)

ENGLISH ABSTRACT: Glutathione (GSH), a tripeptide consisting of glutamate, cysteine and glycine, is the most ubiquitous non‐protein intracellular thiol in a large variety of organisms, including plants, animals and fungi. ...
