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 ...
Analysis of microbial populations associated with a sorghum-based fermented product used as an infant weaning cereal.
The incidences of diarrhoeal episodes in infants and children have mostly been associated with the consumption of contaminated weaning foods. This is especially true in developing countries where factors such as the lack ...
Development of a laboratory river model to determine the environmental impacts of key xenobiotic compounds.
Microorganisms are increasingly used in toxicological studies to determine potential environmental impacts of xenobiotic compounds. A multi-stage laboratory model was developed to facilitate the examination of environmental ...
