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
(University of the Western Cape, 2008)Actinomycetes are Gram-positive bacteria that form filamentous branching hyphae with asexual spores. They occur in a variety of environments and are important industrially and pharmaceutically. The aims of this study were ... -
Iterative helical real-space reconstruction of histone octamer tubular crystals and implications for the 30 nm chromatin fiber
(University of the Western Cape, 2006)This thesis investigated the helical structure of core histone octamers to discover interacting surfaces and their relevance to the compaction of nucleosome arrays into the chromating fiber. -
Laccases from actinomycetes for lignocellulose degradation
(University of the Western Cape, 2012)Lignocellulose has a complex structure composed mainly of lignin, hemicellulose and cellulose. Several enzymes are needed for the degradation of lignocellulose into simple sugars. Actinomycetes are known to produce laecases ... -
Laccases from actinomycetes for lignocellulose degradation
(University of the Western Cape, 2012)The purpose of this study shows that lignocellulose has a complex structure composed mainly of lignin, hemicellulose and cellulose. Several enzymes are needed for the degradation of lignocellulose into simple sugars. ... -
Marine bacteria as a potential source for novel antimicrobial compounds
(University of the Western Cape, 2020)The high rate of rediscovery of known compounds has led to a decline in the discovery of novel natural products. The high biodiversity of organisms growing in extreme conditions such as oceans has led to the increased ... -
Matrix comparison of isolation conditions for secondary metabolite producing marine sponge associated bacteria
(University of the Western Cape, 2015)The discovery of novel secondary metabolites has declined significantly in recent years whereas there is a rise in the number of multi-drug resistant pathogens and other types of diseases. The decline in natural product ... -
Methylgyoxal signalling in Phaseolus vulgaris under phosphate deficiency
(UWC, 2020)In this study, we observed that phosphate (P) deficiency stunted plant growth and produced plants with poor morphological characteristics (yellow and small leaves). Furthermore, we treated plants with 0.8 mM (control) and ... -
The microbial composition of a natural methanogenic consortium
(University of the Western Cape, 2005)Wetlands account for approximately 20% of annual global methane emissions. Many wetlands receive inputs of organic matter, nutrients, metals and various toxic compounds from adjacent agricultural and industrial areas. The ... -
Microbial diversity of Antarctic Dry Valley mineral soil
(University of the Western Cape, 2004)Antarctica provides some of the most extreme environments on earth. Low temperatures, low water availability and nutrient deficiency are contributing factors to the limited colonisation of Antarctic biotopes, particularly ... -
Microbial diversity of the Namib Desert salt pans
(University of the Western Cape, 2015)Salt pans are a characteristic feature of many dry deserts. The microbial communities inhabiting salt pans are thought to be particularly complex and are generally dominated by halophilic microorganisms. Although saline ... -
Microbial quality and safety of ostrich meat
(University of the Western Cape, 2010)The aim of this study was to determine the quality of slaughtered ostrich meat and to evaluate the ostrich slaughter process, to determine whether ostrich meat are contaminated by the in-house slaughtering practices and ...
