Bacterivory of three freshwater ciliates isolated from Blackbarough Spruit in KwaZulu-Natal, South Africa.
(2021)Abstract available in PDF. -
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, ... -
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. -
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 ... -
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 ... -
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 ... -
Clinical strains of mycobacterium tuberculosis induce strain-specific patterns of cytokine production, gene expression and pathway changes in pulmonary alveolar epithelial cells.
(2016)The epidemiological success of M. tuberculosis strains, dominant in different geographic regions globally, may be ascribed to a subversion of the host‟s protective immune response. The increasing prevalence of F15/LAM4/KZN, ... -
The culture-independent analysis of fungal endophytes of wheat grown in KwaZulu-Natal, South Africa.
(2016)Fungal endophytes are of interest due to their diverse taxonomy and biological functions. A range of definitions exists based on their identity, morphology, location and relationship with their host. Fungal endophytes ... -
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 ... -
Development of a bioreactor system using a pine bark matrix for the removal of metal ions from synthetic aqueous solutions.
(2013)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 ... -
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 ... -
Diversity of quorum sensing pherotypes amongst ecotypes of plant-associated Bacillus subtilis sensu lato isolates.
(2021)Ecologically-adapted populations, or ecotypes, are species forms that are functionally adapted to particular habitat niches. Bacterial ecotypes are challenging the significance and implications of ecological adaptation ... -
Genetic characterisation of an indigenous plasmid in xanthomonas albilineans.
(1999)Abstract available in PDF file. -
Genetic manipulation of saccharomyces cerevisiae for improved ethanol production from d-xylose.
(1999)No abstract available. -
Heterologous expression and application of lipolytic enzymes for mitigation of lipophilic compounds in eucalyptus species.
(2017)Abstract available in PDF file. -
A histopathological study on selected bacterial vascular diseases with emphasis on ultrastructure.
(1975)No abstract available. -
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. ...
