An investigation of the plants used medicinally In self-care in the Bredasdorp / Elim region
(University of the Western Cape, 2004)Much of the traditional medicinal plant knowledge is to a large extent known by the older generations. This knowledge is at risk of disappearing due to not being passed down to younger members of the respective families ... -
Investigation of the role of AtNOGC1, a guanylyl cyclase protein in response to abiotic and biotic stress
(University of the Western Cape, 2018)Agricultural production is one of the most important sectors which provide food for the growing world population which is estimated to reach 9.7 billion by 2050, thus there is a need to produce more food. Climate change, ... -
Investigation of the role of the ubiquitin-like DWNN domain in targeting Retinoblastoma Binding Protein 6 to nuclear speckles
(University of the Western Cape, 2018)Magister Scientiae - MSc (Biotechnology) -
Investigation of the Stress-Induced Nuclear Localisation of Retinoblastoma Binding Protein 6 (Rbbp6) and its Role in Ubiquitination Of Y-Box Binding Protein-1 (Yb-1)
(University of the Western Cape, 2017)Retinoblastoma Binding Protein 6 (RBBP6) is a 200 kDa RING finger-containing human protein known to serve as an E3 ubiquitin ligase, and to play a role in ubiquitination and suppression of the tumour suppressor p53. It ... -
Involvement of abscisic acid and H2O2 in antioxidant enzyme activities mediated by nitric oxide synthase-like activity in maize
(University of the Western Cape, 2018)In recent years, nitric oxide (NO) has emerged as an important endogenous plant signalling molecule that mediates many developmental and physiological processes. NO regulates the activity of antioxidant enzymes in response ... -
The isolation and characterisation of a novel siderophore from the marine bacterium Thalassomonas viridans
(University of the Western Cape, 2022)Natural products (NPs) produced by bacteria, fungi, plants, and marine animals include a large group of diverse chemical entities that display a broad range of biological activities. NPs are widely used for various ... -
Isolation and characterisation of a xylanase producing isolate from straw-based compost
(University of the Western Cape, 2012)Lignocellulosic biomass, a waste component of the agricultural industry, is a promising source for use in bioethanol production. Due to a complex structure, the synergistic action of lignocellulosic enzymes is required to ... -
Isolation and characterisation of esterases from thermophilic Actinomyces
(University of the Western Cape, 2010)Alternative sources of fuel are required worldwide, and bio-ethanol is the leading candidate. Lignocellulosic biomass, a waste component of the agricultural industry, is a promising renewable source. Due to its complex ... -
Isolation and characterisation of leaf endophytic bacteria from weed plants for enhancing salinity stress tolerance in Brassica napus
(University of the Western Cape, 2020)In an ever changing environment, plants are constantly challenged by various abiotic stresses such as salinity, which limits global crop production. This directly affects food availability for the global population, which ... -
The isolation and characterisation of novel natural products from marine bacterial symbionts
(University of the Western Cape, 2015)Drug-resistant infections are a global health crisis and drastically hinder the treatment options to effectively combat disease. Today, natural products remain an important source of novel drug candidates. Micro-organisms, ... -
Isolation and characterization of bacterial endophytes for growth promotion of Phaseolus vulgaris under salinity stress
(University of the Western Cape, 2020)As the global human population grows, so does the demand for faster food production rates. Owing to this, agricultural practices have had to expand and move into semi-arid and arid regions, too, where frequent irrigation ... -
Isolation and characterization of plant growth promoting endophytic bacteria from Eriocephalus africanus roots]
(University of the Western Cape, 2018)Endophytic bacteria are known to have an endosymbiotic relationship with plants and provide them with many beneficial properties. These bacteria stimulate plant hormones, provide protection from pathogens and increase ... -
Isolation and characterization of plant growth promoting endophytic bacteria from Medicago lupulina for enhanced drought tolerance in Maize
(University of the Western Cape, 2019)Maize is one of the major staple foods in many African nations however, this crop is sensitive to environmental stressors. Drought is a major environmental stressor affecting maize production. Due to global warming, drought ... -
Isolation and characterization of stem endophytic bacteria from weed plants for enhancing Vanadium tolerance in Brassica napus
(University of the Western Cape, 2019)Bacterial endophytes are able to improve the growth of their hosts through a number of different mechanisms such as nutrient uptake regulation, plant hormone production and regulation, siderophore production and phosphate ... -
Isolation and identification of PNP-A homologues from Xerophyta viscosa Baker
(University of the Western Cape, 2004)Maintenance of growth, development and normal physiological processes remains crucial for the survival of plants. Plant hormones are described as integrators of external signal and internal developmental process in plants. ... -
Isolation and preliminary characterization of bacteriophages of thermophilic Bacillus and Geobacillus species
(University of the Western Cape, 2015)Thermophilic bacteriophages provide simple model systems for understanding biochemical and biological adaptation mechanisms at elevated temperatures. The essential objectives of this study were to characterise the ... -
Isolation, expression, purification and characterisation of a novel acetyl xylan esterase from streptomyces species ORS10
(University of the Western Cape, 2012)Lignocellulosic biomass represents an important renewable resource for biofuels production. Lignocellulosic biomass is comprised of cellulose, hemicellulose and lignin. Lignocellulosics are highly recalcitrant to enzymatic ... -
Isolation, identification and characterization of novel actinomycetes from Antarctic soil samples
