The nutritive value of Italian ryegrass (Lolium multiflorum) selected for high dry matter and nonstructural carbohydrate contents.
In traditional forage breeding programmes, breeders have spent decades improving the agronomic characteristics of grasses, such as herbage yield, persistence and resistance to diseases, without considering the nutrient ...
Rapid prediction of multi-drug resistance in clinical specimens of Mycobacterium tuberculosis.
Conventional drug susceptibility testing techniques, the ‘gold standard’ for M. tuberculosis are slow, requiring about 3-6 weeks from a positive culture. This diagnostic delay, before initiation of appropriate treatment, ...
Design, optimisation and costing of a novel forced-upflow bioreactor for bioremediation of leachates from selected landfill sites in KwaZulu-Natal.
Most waste generated in South Africa is sent to landfills for disposal, and although it is confined in specific areas, it can potentially affect both above and below ground water resources, impacting environmental and ...
Regulation of the thioredoxin system in Saccharomyces cerevisiae.
The thioredoxin system consisting of thioredoxin (Trx), thioredoxin reductase and NADPH plays a significant role in a large number of redox-dependent processes such as DNA synthesis and anti-oxidant defense. Elevated levels ...
Studies on acid phosphatases of Trypanosoma congolense.
Bloodstream forms of African trypanosomes, which endocytose macromolecules exclusively through their flagellar pockets, contain an acid phosphatase (AcP) activity in this organelle. In the present thesis, AcP activity ...

Development of a bioreactor system using a pine bark matrix for the removal of metal ions from synthetic aqueous solutions.
Many industries use, or produce, metal-containing solutions which must be treated for reuse or discharge to sewer. One such treatment is biological and both living and dead materials have been investigated for the abstraction ...

The effects of Sutherlandia frutescens and Fumonisin B1 on Jurkat cells.
The medicinal plant Sutherlandia frutescens (SF) is commonly consumed in South Africa, and is traditionally applied to a range of ailments. Yet its popularity stems from the use of SF as a cancer treatment. This plant ...
Novel cationic lipoplexes : characterization in cell culture in vitro and in vivo.
Amongst the more promising non-viral DNA vehicles are liposomes, with those derived from cationic lipids showing significant potential, despite moderate transfection levels in vivo. This study has investigated the effect ...
