Screening, identification and characterisation of bacteriocins produced by the wine isolated LAB

Ndlovu, Joseph Buyani (Stellenbosch : Stellenbosch University, 2013-03)

ENGLISH ABSTRACT: Lactic acid bacteria (LAB) play a vital role in reducing wine acidity and also contributing to its aroma and flavour. However, they can also be responsible for many wine spoilage problems that compromise ...
Assessing the compatibility and aroma production of NT 202 Co-Inoculant with different wine yeasts and additives

Scholtz, Marene (Stellenbosch : Stellenbosch University, 2013-03)

ENGLISH ABSTRACT: The influence of malolactic fermentation (MLF) in most red and some white wines is one of many factors that determine or influence wine quality, because it affects the flavour and sensory profile of ...
Mode of action studies of defensin peptides from native South African Brassicaceae species

Barkhuizen, Helmien (Stellenbosch : Stellenbosch University, 2013-03)

ENGLISH ABSTRACT: Plant defensin peptides have become promising and attractive candidates to be used as antifungal agents in agricultural biotechnology. These peptides have a broad spectrum antifungal activity and play ...
Development of infrared spectroscopic methods to assess table grape quality

Daniels, Andries Jerrick (Stellenbosch : Stellenbosch University, 2013-03)

ENGLISH ABSTRACT: The two white seedless table grape cultivars, Regal Seedless and Thompson Seedless fulfil a very important role in securing foreign income not only for the South African table grape industry, but the ...
A case study of source-sink relationships using shoot girdling and berry classification (Vitis vinifera L. cv. Cabernet Sauvignon)

Joubert, Chandre (Stellenbosch : Stellenbosch University, 2013-03)

ENGLISH ABSTRACT: The relationships between leaf and fruit represent a fundamental concept in perennial plants. This concept allows to understand and to manage, with regard to farming, the balance of a vine, which is ...
Volatiles playing an important role in South African Sauvignon blanc wines

Van Wyngaard, Elizma (Stellenbosch : Stellenbosch University, 2013-03)

ENGLISH ABSTRACT: Sauvignon blanc wines have become progressively more important in the commercial market. Extensive research is being done in various countries to gain more understanding about the aroma compounds found ...
Sensor technology to assess grape bunch temperature variability in Vitis vinifera L. cv. Shiraz

Moffat, Tessa (Stellenbosch : Stellenbosch University, 2013-03)

ENGLISH ABSTRACT: The microclimate environment around the bunch is complex. The spatial distribution of leaves as well as bunch position and morphology impact on the path of direct radiation received by the berries. Canopy ...
The impact of wine yeast strains on the aromatic profiles of Sauvignon blanc wines derived from characterized viticultural treatments

Von Mollendorff, Anke (Stellenbosch : Stellenbosch University, 2013-03)

ENGLISH ABSTRACT: Grape must is a complex medium, and during wine production numerous biochemical pathways and metabolic reactions are taking place simultaneously to produce a specific taste and aroma. Microorganisms, ...
Channelling metabolic flux away from ethanol production by modification of gene expression under wine fermentation conditions

Heyns, Eva Hutton (Stellenbosch : Stellenbosch University, 2013-03)

ENGLISH ABSTRACT: There is a global demand for technologies to reduce ethanol levels in wine without compromising wine quality. While several chemical and physical methods have been developed to reduce ethanol in finished ...
Investigating the secretome of non-Saccharomyces yeast in model wine

Mostert, Talitha Tanya (Stellenbosch : Stellenbosch University, 2013-03)

ENGLISH ABSTRACT: Proteins from various sources, including grape berry cells, yeast, bacteria and fining agents e.g. albumin and casein, have previously been identified in wine. These proteins play various critical roles ...
Bioprocess monitoring and chemometric modelling of wine fermentations

Garlick, Jessica Louise (Stellenbosch : Stellenbosch University, 2013-03)

ENGLISH ABSTRACT: Wine fermentation is a continuously changing biological process whereby the raw product, grape juice is transformed into a high value product wine. In an ideal situation the fermentation kinetics of ...
Generating lower ethanol yields in fermentations by Saccharomyces cerevisiae via diversion of carbon flux towards the production of fructo-oligosaccharides

Brandt, Bianca Anina (Stellenbosch : Stellenbosch University, 2013-03)

ENGLISH ABSTRACT: There is a growing international consumer demand for the production of lower ethanol wines. This can be attributed to various qualitative, social, economic and health concerns that are associated with ...
Grape and wine quality of V. vinifera L. cv. Cabernet Sauvignon/99R in response to irrigation using winery wastewater

Schoeman, Charl (Stellenbosch : Stellenbosch University, 2012-12)

ENGLISH ABSTRACT: Grapevine performance and wine quality are influenced by various factors, two of the most important being the availability and quality of irrigation water. In relatively dry countries such as South Africa ...
