An investigation into the antimicrobial and immune modulatory effects of Sutherlandia frutescens and Salvia africana-lutea extracts and their respective biogenic nanoparticles
(University of the Western Cape, 2020)
The prevalence of cancer and antibiotic-resistant microbes has led to the necessity of affordable, efficacious, non-toxic and easily accessible therapeutic approaches. There is numerous anecdotal evidence that African ...
Proteomic and metabolomic characterisation of novel wine yeasts: towards the evaluation and improvements of their ability to produce aromatic sauvignon blanc wines
(University of the Western Cape, 2017)
Wine yeast Saccharomyces cerevisiae and wild yeasts e.g. Torulaspora delbrueckii forms an integral
part of wine production by converting relatively 'neutral' flavoured Sauvignon blanc grape must into
varietal aromatic ...
The effects of high temperature stress on the enzymatic antioxidant system in Zea mays
(University of the Western Cape, 2017)
High temperature stress is synonymous with the attenuation of plant growth, metabolism and eventually death resulting in major loss of crop productivity worldwide. Part of the metabolic perturbations associated with heat ...
Green synthesis and characterization of gold nanoparticles from South African plants and their biological evaluations
(University of the Western Cape, 2019)
The field of nanotechnology continues to offer solutions for biotechnologists whose
target is to improve the quality of life by finding new therapies to combat diseases.
Gold nanoparticles (AuNPs) have been showing great ...
Structure, enzymology and genetic engineering of Bacillus sp. RAPc8 nitrile hydratase
(University of the Western Cape, 2005)
Microbial nitrile hydratases (NHases) are important industrial enzymes that catalyse the conversion of nitriles to the corresponding amides. A thermostable, cobalt-type
Bacillus sp. RAPc8 NHase was previously cloned and ...
Public participation as governance the role of catchment forums in water governance Mluleki Matiwane
(2012)
Catchment forums are concerned groups of people that come together on a voluntary basis in a specific area. They share the same goal and purpose to achieve - sustainable water resources management. These Catchment Forums ...
Molecular detection and genetic manipulation of the Black Queen Cell Virus
(University of the Western Cape, 2002)
The South African isolate of the Black Queen-Cell Virus (BQCV), a honeybee virus, was previously found to have an 8550 nucleotide genome excluding the poly(A) tail. Its genome contained two ORFs, a 5'-proximal ORF encoding ...
Isolation, identification and characterisation of novel actinobacteria from Zambian hot-springs
(2011)
Actinomycetes are ubiquitous in many environments such as soil, activated sludge and water.Besides the genus Streptomyces, which has been extensively exploited, members of other genera including Micromonospora have been ...
Analysis of the early events in the interaction between Venturia inaequalis and the susceptible Golden Delicious apple (Malus x domestica Borkh.)
(University of the Western Cape, 2014)
Apple (Malus x domestica) production in the Western Cape, South Africa, is one of the major contributors to the gross domestic product (GDP) of the region. The production of apples is affected by a number of diseases. One ...
Structural and functional characterisation of a novel signalling molecule in Arabidopsis thaliana
(2011)
Nitric Oxide (NO) influences a wide range of physiological processes in plants including growth and development, responses to abiotic and biotic stress and pathogen responses. NO binds to the heme group of the mammalian ...
