The role of post translational modifications in the regulation of binding of linker histone Hho1 to chromatin in Saccharomyces cerevisiae
(University of the Free State, 2015-02)
The eukaryotic genome is functionally organized into a highly ordered nucleoprotein
structure, chromatin. Apart from the four nucleosomal core histones, the linker histone is
pivotal to fluidity and compaction of chromatin. ...
Heterologous expression of cytochrome P450 monooxygenases in different ascomycetous yeasts
(University of the Free State, 2012-07)
Cytochrome P450 monooxygenases (P450) are a diverse, ubiquitous family of important enzymes which catalyze a variety of activities. Their outstanding abilities to hydroxylate non-activated hydrocarbons make them attractive ...
Effect of cultivation conditions on the dimorphism of and heterologous protein production by Arxula adeninivorans
(University of the Free State, 2007-11)
Arxula adeninivorans strain LS3, a dimorphic yeast with potential for biotechnological applications, has in recent years has been studied for the production of heterologous proteins. The growth kinetics of this species and ...
Oxylipins in Cryptococcus neoformans and related yeasts
(University of the Free State, 2007-11)
English: Literature shows that Cryptococcus neoformans is an important human pathogen
responsible for many deaths worldwide. To compound this, treatment of cryptococcal
infections has over the years been difficult. This ...
The lipid composition of the yeast genus Saccharomycopsis Schiönning
(University of the Free State, 2004-11)
English: In this study, the construction of a forecasting model, using intracellular fatty acid composition as indicator, was attempted to assist in the search for yeasts capable of producing 3-hydroxy oxylipins. In order ...
Yeast sensors reveal chloroquine as yeast fertility drug
(University of the Free State, 2013-11)
English: Previous unpublished research by Kock and co-workers indicated that the antimalarial drug chloroquine (CQ) stimulates yeast sexual stages (biosensors). Consequently several indicator yeasts (Eremothecium ashbyi, ...
Long-chain fatty acid compositions and volatile metabolite patterns of yeasts associated with wine
(University of the Free State, 1987-05)
A) In Chapter 1 the need for a yeast identification system in the wine
industry is highlighted. The definition, as well as taxonomic
development of the ascomycetous yeasts are discussed as well as the
problems ...
The role of yeasts during the ripening of salami
(University of the Free State, 1999-03)
Yeasts play a substantial role in the processing of salami, being present at high
numbers during the ripening stages contributing to aroma and flavour development.
Accordingly, the yeasts occurring as natural microflora ...
Yeasts as adjunct starter cultures in cheese making
(University of the Free State, 2011-01)
A literature review on the role and presence of microorganisms in cheese was reviewed. The biochemical pathways involved in the cheese manufacture from the milk to the resultant cheese curd at the end of manufacturing were ...
Dicarboxylic acid production by Yarrowia lipolytica strains
(University of the Free State, 2003-05)
English:Dicarboxylic acids are value added products, which can be prepared by diterminal oxidation of n-alkanes by bacteria or yeasts with a block in β-oxidation. Yarrowia lipolytica is one of the alkane-utilizing yeasts ...
