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 silver nanoparticles synthesized using eucomis autumnalis bulb aqueous extract, their characterization and in vitro antibacterial activity
(University of the Western Cape, 2023)Antimicrobial resistance (AMR) is a growing global problem that poses a significant threat to public health. AMR arises when microorganisms become resistant to drugs that were initially designed to kill them. The application ... -
Biogenic synthesis of gold nanoparticles using red and green pear fruit extracts
(University of the Western Cape, 2019)There has been a growing interest in the design of biocompatible and environmentally affable nanoparticles (NPs) among scientists to develop novel and safe biomaterials for use in various biomedical applications. This can ... -
A biogeographic, phylogenetic and taxonomic evaluation of South African orthopteran species (Orthoptera: Pneumoridae)
(University of the Western Cape, 2021)The order Orthoptera contains a wide diversity of species and is the most speciose of the polyneopteran insect lineages. In South Africa, the orthopteran fauna is abundant and diverse, with approximately 88% of all Southern ... -
A bioinfonnatics approach to the study of the transcriptional regulation of AMPA Glutamate receptors (GRIAs) and genes whose expression are co-regulated with GRIAs
(University of the Western Cape, 2009)It was postulated that each gene has three main sets of transcriptional elements: one which is gene-specific, one which is family-specific, and a third which is tissue-specific. The starting hypothesis for this project had ... -
Bioinformatics and polymerase chain reaction: Tools to determine the host specificity of Salmonella typhi murium
(University of the Western Cape, 2002)The nucleotide primer pair, Redl and Red2, was designed from the nucleotide sequence obtained from the NCBI database (Fig. 2.1). This nucleotide sequence encodes for the Salmonella typhimurium invasion gene D protein ... -
Biological and enzymatic activity of actinobacteria associated with aloe ferox
(University of the Western Cape, 2023)Antimicrobial resistance is a global crisis that has been on the rise for decades, threatening the health and safety of many nations. This highlights the need to discover novel antimicrobial compounds to combat already ... -
Biological approach to improving the evaporation rates of mine wastewater desalination brine treated in evaporation ponds
(University of the Western Cape, 2021)The disposal of brine effluent from inland wastewater desalination plants is a growing global problem with adverse economic and environmental implications because of the substantial cost associated with its disposal and ... -
Biological properties of selected flavonoids of rooibos (Aspalathus linearis)
(University of the Western Cape, 2007)Bioactivity-guided fractionation was used to identify the most potent antioxidant and antimutagenic fractions contained in the methanol extract of unfermented rooibos (Aspalathus linearis), as well as the bioactive principles ... -
Biomonitoring as a means to determine the pollution level in Stellenbosch
(University of the Western Cape, 1991)A pollution survey was done in Stellenbosch, along two transects. One was south-east and the north-east of the Oorrobrick brickfield the focal point of this study. Pine and Oak trees, chasman the leaves and lichens were ... -
Biomonitoring of heavy metals in the Eerste River catchment area
(University of the Western Cape, 2020)The risk of increasing global pollution dictates the need to understand environmental processes and develop innovative ways to monitor pollution levels and address associated problems. In order to address this need, this ... -
Bionomics of vector-borne diseases in sites adjacent to lakes Victoria and Baringo in Kenya
(University of the Western Cape, 2016)Bionomics of vector-borne pathogens (VBPs) is a complex phenomenon that involves understanding the ecology of arthropod borne pathogens and vertebrate hosts potentially involved in their transmission cycles. Investigations ... -
Bioprospecting for bioactive polysaccharides from marine algae endemic to South Africa
(University of the Western Cape, 2016)Fucoidan is a marine-derived sulphated polysaccharide with bioactive properties ideal for the food, chemical and pharmaceutical industries. The polysaccharide consists largely of L-fucose, has a highly heterogeneous structure ... -
Biosimilar’s Growth in Pharmerging Markets: An Analysis of the Regulatory Environments
(University of the Western Cape, 2020)The introduction of biosimilars to health care markets across the globe has had some success in increasing competition and improving the cost of healthcare. While savings are important for driving the biosimilar uptake, ... -
Biosurfactant screening through metagenomic and culture-based approaches
(University of the Western Cape, 2022)The biosurfactant market is still predominantly represented by the three main products: surfactin, sophorolipids, and rhamnolipids, mainly as a result of the high cost and low yield associated with biosurfactant production. ... -
The Birch and Swinnerton-Dyer Conjecture for elliptic curves.
(University of the Western Cape, 2014)The aim of this dissertation is to provide an exposition of the Birch and Swinnerton-Dyer Conjecture, considered by many to be one of the most important unsolved problems in modern Mathematics. A review of topics in Algebraic ... -
