The development of assays for atractyloside and its localisation in rat tissue.
An extract of the tuber of Callilepis laureola is regarded as the source of a powerful therapeutic agent, known as Impila. Its use is associated with fatal hepatic and renal necrosis, the renal toxin being atractyloside ...
Type IV collagenase and cathepsins L and H : proteinases involved in tumour invasion.
The collagenolytic proteinases, type IV collagenase and cathepsins Land H, have been implicated in tumour invasion and metastasis, by virtue of their degradative action on the extracellular matrix barriers traversed by ...
Bioremediation of oil-contaminated soil : a South African case study.
In 1990, an oil recycling plant situated in Hammarsdale, South Africa, was decommissioned and a decision was taken by management to rehabilitate the site in preparation for resale. The heavily impacted area covered over ...
Quantification of fungal degradation of pinus patula and eucalyptus grandis.
Previous studies of fungal decay have mainly examined long term effects of wood decay. In contrast, the present work, was designed to quantify fungal degradation of wood during incipient decay. Three facultatively ...
Development of a code of practice for co-disposal to obviate inimical environmental impacts of generated gases and leachates.
Despite its phasing out in numerous countries, such as Germany and the U.S.A., co-disposal of hazardous waste with municipal solid waste continues to be widely practised in South Africa. Co-disposal utilises properties ...

Installation, commissioning and preliminary microbiological and operational investigations of full-scale septic tank digestion of sewage.
This study investigated the commissioning and maintenance of a Pennells two-tank bioreactor system with specific reference to its application in rural areas of KwaZulu- Natal, South Africa to treat sewage and generate ...
Exploitation of indigenous fungi in low-cost ex situ attenuation of oil- contaminated soil.
The central aim of this study was to determine if indigenous fungi of an oil-contaminated soil could be effectively used in a low-cost bioremediation of the soil. Since some of the contaminant had been present at the ...
The influence of soil particle surfaces and soil porosity on the biodegradation of key refuse leachate organic molecules.
Many studies have been undertaken to determine the effects of soil and soil properties on migrating metal pollutants. Organic pollutants, however, in addition to their interactions with soil components , are also susceptible ...
Breeding for disease resistance to the major foliar pathogens of dry beans (Phaseolus vulgaris) in South Africa.
Resistances to bean common mosaic virus, halo, common and Ascochyta blight, angular leaf spot, anthracnose and rust pathogens of beans in South Africa were combined by reverse dichotomous crossing. Full resistance to ...
