Aptamer selection against GFRa1 for its application in the prognosis of breast cancer
(University of the Western Cape, 2019)Breast cancer is the second most common cancer amongst South African women. Despite ongoing efforts to combat breast cancer, current prognostic and/or therapeutic monitoring methods are limited since very little improvement, ... -
The assessment of the bactericidal effect of green synthesized silver nanoparticles against a panel of infectious microorganisms
(University of the Western Cape, 2016)The emergence of multiple drug resistant microorganisms poses a major threat to human life. These microorganisms have made the currently used antibiotics ineffective and therefore continue to thrive. Therefore, there is a ... -
An assessment of the dietary intake of pregnant women in the West Coast / Winelands region, Western Cape Province: relation to low birth weight
(University of the Western Cape, 2008)This secondary analysis aimed to develop dietary scores to assess the dietary intake of pregnant women in the West Coast/ Winelands region and determine the association with LBW. Further to determine the association between ... -
Association between antioxidant activities and drought responses of two contrasting sugar beet genotypes
(University of the Western Cape, 2017)Sugar beet (Beta vulgaris L), which belongs to the Amaranthaceae family is a biennial crop widely used as a source of domestic sugar in the European countries, United States, China and Japan. However, in South Africa, sugar ... -
AtNOGC1 protein bioelectrode for the determination of stress signalling molecules - Nitric Oxide (NO), Carbon Monoxide (CO) and Calcium ion (Ca2+)
(University of the Western Cape, 2018)It has been estimated that the world population will reach about 10 billion by the year 2050 and in order to accommodate the increased demand of food, the world agricultural production needs to rise by 70 % in the year ... -
Bacteriophage diversity in haloalkaline environments
(University of the Western Cape, 2013)There are limited reports on virus population in haloalkaline environments; therefore the aim of this study was to investigate the genetic diversity and biology of bacteriophage communities in these environments. Bacteria ... -
Barley anther culture: determining the optimal pre-treatment for green plant regeneration
(2013)Doubled Haploid (DH) Technology is an important tool for plant breeding and biotechnological applications as it accelerates the breeding cycle of plants by shortening the time required to attain homozygosity. Anther culture ... -
Bioactive actinobacteria associated with two South African medicinal plants, Aloe ferox and Sutherlandia frutescens
(University of Western Cape, 2021)Actinobacteria, a Gram-positive phylum of bacteria found in both terrestrial and aquatic environments, are well-known producers of antibiotics and other bioactive compounds. The isolation of actinobacteria from unique ... -
Bioactivity and genome guided isolation of a novel antimicrobial protein from Thalassomonas viridans
(University of the Western Cape, 2019)The continued emergence of bacterial resistance to the antibiotics currently employed to treat several diseases has added to the urgency to discover and develop novel antibiotics. It is well established that natural products ... -
A biochemical and proteomic analysis of sugargraze sorghum under hyperosmotic stress
(University of the Western Cape, 2015)Sugargraze is a moderately drought tolerant sweet sorghum hybrid which is ideal for grazing, winter stand over and pit silage. A major advantage that Sugargraze has over other forages is its very high sugar content which ... -
Biochemical characterisation of an alpha-amylase with pullulan hydrolase type III characteristics derived from a hot spring metagenomics library
(University of the Western Cape, 2024)The field of metagenomics has provided biotechnological researchers with new enzymes and insight into previously unknown enzyme families with potential for novel modes of action and being able to function under extreme ... -
Biochemical characterization of β-xylosidase and β-glucosidase isolated from a thermophilic horse manure metagenomic library
(University of the Western Cape, 2020)The complete degradation of recalcitrant lignocellulose biomass into value-added products requires the efficient and synergistic action of lignocellulose degrading enzymes. This has resulted in a need for the discovery of ... -
Biocontrol potential of fungal endophytes against Fusarium proliferatum in maize
(University of the Western Cape, 2022)Fusarium proliferatum is a fungal pathogen that is the cause of numerous diseases in various crops of fruit and vegetables. About 25% of the maize crops harvested annually are affected by mycotoxins produced by F. ... -
Biodiscovery of Novel Bioactivities from the South African Marine Environment
(University of the Western Cape, 2016)There is currently a global health crisis taking place, which is the increasing occurrence of drug-resistant pathogens within clinical microorganisms. Drugresistant pathogens are increasingly becoming more difficult to ... -
Biogenic synthesis of gold nanoparticles using red and green pear fruit extracts
