Examining intra- and interspecific variability in the diet and carbon and nitrogen stable isotope ratios of kingklip and monkfish caught off the West and South coasts of South Africa
(University of Western Cape, 2020)
Kingklip (Genypterus capensis) and monkfish (Lophius vomerinus) and are ecologically and economically important demersal fish species that are found along both the eastern and western parts of southern Africa’s coastline. ...
Empirical and model derived respiration responses to climate in different soils of an arid South African ecosystem
(2009)
This study examined the magnitude of soil CO2 efflux in an arid South African ecosystem, the flux responses as well as those of key limiting nutrients to soil temperature increases and moisture reductions consistent with ...
Screening for subtate tolerant Geobacillus pallidus RAPc8 nitrile hydratase
(University of the Western Cape, 2009)
In this study G. pallidus RAPc8 NHase mutants were screened for reduced substrate inhibition compared to the wild type enzyme. Wild type and mutant enzymes were expressed and purified using hydrophobic interaction ...
Engineering homoaromatic substrate specificity into aliphatic-specific Geobacillus pallidus RAPc8 nitrile hydratase
(University of the Western Cape, 2007)
Geobacillus pallidus RAPc8 is a thermophilic nitrile-degrading isolate, obtained from thermal sediment samples of a New Zealand hot spring. The G. pallidus RAPc8 NHase gene has been cloned and expressed in E. coli. The ...
Phylogenetic diversity of nifH genes in Marion Island soil
(University of the Western Cape, 2006)
The microbial life of sub-Antarctic islands plays a key role in the islands ecosystem, with microbial activities providing the majority of nutrients available for primary production. Knowledge of microbial diversity is ...
Monitoring of heavy metals in the bottelary river using typha capensis and phragmites australis
(2005)
The aim of this study was to use plants to determine the degree of heavy metal contamination in water and sediments in order to effectively monitor and provide possible recommendation to improve the water quality in the ...
The C-economy, nutritional benefits and symbiotic performance of dual inoculated Phaseolus vulgaris (L.) plants, under variable nutrient conditions
(University of the Western Cape, 2010)
The tripartite symbiosis between Phaseolus vulgaris, arbuscular-mycorrhiza and the nodule bacteria, Rhizobia have been the focus of many studies ranging over a number of decades, however these studies have failed to answer ...
Modification of nanostructured carbon based supports for direct methanol fuel cells
(University of the Western Cape, 2022)
Palladium (Pd) and Palladium-Ruthenium (Pd-Ru) nanoparticles supported by various carbon
nanomaterials which include graphene oxide (GO), reduced graphene oxide (rGO) and multiwalled
carbon nanotubes (MWCNTs) with their ...
Respiratory and photosynthetic C and N metabolism of nodulated Lupin roots during phosphorus deficiency
(University of the Western Cape, 2010)
Growth of symbiotic legume hosts is P limited, because of the high energetic requirements associated with N2 fixation. Attempts to overcome P deficiency in soils where legumes are grown involve addition of P-based fertilisers. ...
