Microbial biotransformation of kimberlite ores.
(2008)Microbial leaching plays a significant role in the natural weathering of silicate containing ores such as diamond-bearing kimberlite. Harnessing microbial leaching processes to pre-treat mined kimberlite ores has been ... -
Application of bacterial bioflocculants for wastewater and river water treatment.
(2008)Dyes are often recalcitrant organic molecules that produce a colour change and contribute to the organic load and toxicity of textile industrial wastewater. Untreated effluent from such sources is harmful to aquatic life ... -
The develolpment of a rapid diagnostic test for the detection of haemophilus ducrey.
(2010)Aim: To develop an antigen detection test that would quickly exclude H. ducreyi infection in individuals with genital ulcers. Materials and Methods: H. ducreyi strains A54 and A68 were grown on Modified Bieling (MB) ... -
The development of an in vitro system to assess the effect of arbuscular mycorrhizal fungi on cereal crops in KwaZulu-Natal, South Africa.
(2010)Cereal crops such as maize and sorghum are economically important in South Africa (SA) as a staple food diet. In order to meet the needs of South Africa’s growing population, higher yields in crop production need to be ... -
Investigation into the diversity of antifungal aerobic endospore-forming bacteria associated with bulk and crop rhizosphere soil.
(2011)Members of the genus Bacillus are mainly Gram positive, aerobic rod shaped, endospore-forming bacteria that are increasingly being recognised for their ability to promote plant growth and antagonise fungal pathogens. From ... -
Impact of irrigation water on the quality of fresh produce.
(2011)The consumption of minimally processed fresh fruit and vegetables has increased over the past years, mostly because of consumers awareness that fresh produce serves as a good source of vitamins, minerals and fibre. ... -
Effect of fermentation and nutritional conditions on the profile of flavour active ester compounds in beer.
(2011)During fermentation, the yeast Saccharomyces cerevisiae produces a broad range of aroma-active esters that are important for the desirable complex flavour of beer. The sensory threshold levels of these esters in beer are ... -
Strategies for effective bioremediation of water co-contaminated with 1, 2-dichloroethane and heavy metals.
(2011)The production of 1,2-Dichloroethane (1,2-DCA) exceeds 5.44 billion kg per year, and is higher than that of any other industrial halogenated chemical. Improper disposal practices or accidental spills of this compound have ... -
Rapid prediction of multi-drug resistance in clinical specimens of Mycobacterium tuberculosis.
(2011)Conventional drug susceptibility testing techniques, the ‘gold standard’ for M. tuberculosis are slow, requiring about 3-6 weeks from a positive culture. This diagnostic delay, before initiation of appropriate treatment, ... -
The microbiological assessment of a biofiltration system in KwaZulu-Natal (South Africa) treating borehole water containing Mn (II) and Fe (II).
(2013)In the following study, the potential role that microorganisms play in the removal of Mn (II) and Fe (II) was assessed using biofilter sand and water samples collected from a biofiltration system (operated by Umgeni Water ... -
Establishment of in vitro shoot multiplication and short-term embryo storage protocols for single genetic modification events in sugarcane.
(2013)Sugarcane (Saccharum spp. hybrids) is an important economic crop that accounts for more than 80% of world sugar production. Genetic improvement and selection to produce cultivars with traits of interest is difficult in ... -
Impact of microbial and physico-chemical qualities of treated wastewater effluent on receiving water bodies in Durban.
(2013)Increase in magnitude of the global freshwater crisis together with the constantly changing demographics, hydrological variability and rapid urbanization will allow for continuous over exploitation of existing water ... -
Phenotypic and genotypic characterization of Salmonella species isolated from treated wastewater effluents and receiving rivers in Durban.
(2013)Salmonella and Shigella spp. are major pathogens of humans and they cause diseases ranging from mild food poisoning to chronic diarrhoea, especially in children under the age of 5. They are commonly found in the gastrointestinal ... -
Assessment of the diversity of bacteria and methanogenic Archaea in Zebra faeces.
(2013)The need to develop a renewable, environmentally friendly source of energy has become a primary focus in modern science, with bio gas showing considerable potential. Interest in the methanogenic Archaea has therefore grown ... -
Partial purification and characterisation of Phialophora alba xylanases and its application to pretreated sugarcane bagasse.
(2013)Xylan is the major component of hemicellulose and its degradation can be achieved through the hydrolytic action of microbial xylanases. Xylanases have an array of applications one being bioethanol production. The lack ... -
Modelling and optimization of microbial production of hydrogen on agro-municipal wastes.
(2013)The indiscriminate use of fossil fuels has led to global problems of greenhouse gas emissions, environmental degradation and energy security. Developments of alternative and sustainable energy resources have assumed paramount ... -
Complex soil-microorganism-pollutant interactions underpinning bioremediation of hydrocarbon/heavy metal contaminated soil.
(1996)This study evaluated the efficacy of bioremediation as a treatment option for a hydrocarbon and heavy metal contaminated soil. Microbial degradation of hydrocarbons under aerobic, nitrate-reducing and sulphate-reducing ... -
An investigation of the dual co-disposal of a phenolic wastewater and activated sewage sludge with refuse and treatment of high-strength leachate obtained from a closed co-disposal landfill.
(1996)Co-disposal with refuse in a controlled landfill is the cheapest option for the disposal of hazardous waste and, if carefully controlled, can be an effective treatment option. In this present study a high-strength phenolic ... -
Assessing the role of the transcription factor FOXC1 in the expression and regulation of the Adherens junction protein N-Cadherin during corneal endothelium development.
(2011)The proper organization and differentiation of the anterior segment is pivotal for normal eye development. Neural crest-derived POM cells are key contributors to correct anterior segment formation, differentiating to ... -
Role of marine nitrifying bacteria in a closed system with Penaeus monodon.
(1984)In recent years there has been widespread interest in rearing aquatic organisms of nutritional and commercial value (Calaprice, 1976). The most hopeful prospect for marine prawn culture in the United Kingdom (Wickins, ...
