Microbiological investigations into granular sludge from two anaerobic digesters differing in design and industrial effluent purified.
(1995)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 ... -
Bioremediation of heavy metal polluted waters.
(1995)Microorganisms have the potential to remove heavy metals from polluted waters and effluents and may be used in clean-up processes. Microbial associations were enriched for and adapted to grow in nutrient solutions ... -
The influence of soil particle surfaces and soil porosity on the biodegradation of key refuse leachate organic molecules.
(1995)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 ... -
Bioremediation of oil-contaminated soil : a South African case study.
(1996)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 ... -
Development of a code of practice for co-disposal to obviate inimical environmental impacts of generated gases and leachates.
(1996)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 ... -
Genetic manipulation of saccharomyces cerevisiae for improved ethanol production from d-xylose.
(1999)No abstract available. -
Genetic characterisation of an indigenous plasmid in xanthomonas albilineans.
(1999)Abstract available in PDF file. -
P15 trypanosome microtubule associated protein : structure/function analysis and vaccine development for the prevention of African sleeping sickness.
(2001)Trypanosomes are hemoflagellated protozoan parasites causing chagas disease in South America, Leishmaniasis throughout the world, and African sleeping sickness in humans and nagana in animals in Africa. About 55 million ... -
The syndromic management of sexually transmitted diseases : clinical microbiological response in relation to aetiology, susceptibility patterns and co-infection with HIV-1 [electronic resource].
(2002)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 chemically contaminated soil : extraction/analysis methodology development.
(2002)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..
(2002)No abstract available. -
Molecular characterisation of Peronospora parasitica infecting Brassica species.
(2002)Abstract available in PDF file. -
Beta-lactamase mediated resistance in Salmonella spp. at a tertiary hospital in KwaZulu-Natal.
(2008)Extended spectrum (3-lactamases (ESBLs) were characterized in Salmonella spp. isolates from a pediatric ward of a hospital in Durban. Forty one Salmonella spp. were subjected to serotyping, antibiotic susceptibility testing, ... -
Characterisation of chlorinated-hydrocarbon-degrading genes of bacteria.
(2009)1,2-dichloroethane (DCA) is one of the most widely used and produced chemicals of the modern world. It is used as a metal degreaser, solvent, chemical intermediate as well as a fuel additive. This carcinogen is toxic to ... -
Isolation and characterization of antibiotic(s) produced by bacteria from KwaZulu-Natal soils.
(2010)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 ... -
Design, optimisation and costing of a novel forced-upflow bioreactor for bioremediation of leachates from selected landfill sites in KwaZulu-Natal.
(2011)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 ... -
The impact of induced mutations on key nutritional and agronomic traits of sorghum.
(2013)Climate change, shrinking arable land, burgeoning population and malnutrition have made all aspects of crop improvement a critical issue. Of these, nutritional quality of crops is perhaps one of the most important aspects. ... -
Interaction between Mycobacterium tuberculosis and pulmonary epithelium.
(2013)Background Mycobacterium tuberculosis isolates such as the Beijing and F15/LAM4/KZN families dominate in patients. The emergence of extensively drug resistant (XDR) M. tuberculosis isolates raises concern. The need to ... -
The microbiology of ex situ bioremediation of petroleum hydrocarbon-contaminated soil.
(2013-06-18)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 bioreactor system using a pine bark matrix for the removal of metal ions from synthetic aqueous solutions.
(2013-11-06)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 ...
