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 ...
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 ...
Microbiological investigations into granular sludge from two anaerobic digesters differing in design and industrial effluent purified.
Due to a combination of selection criteria, sludges from upflow anaerobic digesters treating industrial waste waters consist primarily of well-settling, dense agglomerates called granules. Quantification of the component ...
The syndromic management of sexually transmitted diseases : clinical microbiological response in relation to aetiology, susceptibility patterns and co-infection with HIV-1 [electronic resource].
HIV-1 is the most prevalent and notorious sexually transmitted pathogen locally, and constantly challenges our foundation of knowledge regarding the classical STIs. The ultimate objective of the syndromic management ...
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 ...
Bioremediation of chemically contaminated soil : extraction/analysis methodology development.
The efficacies of soil extraction methods, namely, Soxhlet, sonication, agitation, alkaline digestion and the ethyl acetate micro-method, for monitoring soil bioremediation were evaluated using three soil types, Swartland, ...
Bioremediation of creosote-contaminated soil by microbial intervention..

Isolation and characterization of antibiotic(s) produced by bacteria from KwaZulu-Natal soils.
This work reports the continued search for new antibiotics in the relatively under investigated region of KwaZulu-Natal, South Africa. A soil bacterium designated strain N8 with antibacterial activity against both Gram-positive ...
The microbiology of ex situ bioremediation of petroleum hydrocarbon-contaminated soil.
Bioremediation is the process whereby the degradation of organic polluting compounds occurs as a result of biochemical activity of macro- and microorganisms. Bioremediation of hydrocarbon contaminated soils can be practised ...
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 ...
