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 ... -
Biochemical investigation of anti-cancer activity of Tulbaghia violacea
(UWC, 2012)Natural products have been a source of many pharmaceutical drugs and a number of drugs that are currently used in the treatment of cancer are derivatives of compounds originally isolated from natural products. There is ... -
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
(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 ... -
Biography in and of an archive : the Shelagh Gastrow Collection and South Africa
(University of Western Cape, 2012)This study is about the recent political history of South Africa. It examined the crucial period of late apartheid, through the political transition into democracy. The study was conducted through the lenses of Shelagh ... -
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 ... -
