Development of nutrition education material for caregivers of immune compromised children in children's homes in the Durban area

Grobbelaar, Hendrina Helena (2011)

Nutrition plays a fundamental role in the care and support of people living with the Human Immunodeficiency Virus (HIV) and children in particular are affected by HIV and the Acquired Immunodeficiency Syndrome (AIDS) ...
Development of a starter culture for the production of Gari, a traditional African fermented food

Edward, Vinodh Aroon (2010)

Cassava, (Manihot esculenta Crantz), is used for the production of a variety of West African foods and ranks fourth in the list of major crops in developing countries after rice, wheat and maize. Gari is one of the most ...
In vitro toxicity testing of phthalocyanines on different cell lines using a continuous laser source

Maduray, Kaminee (2010)

Photodynamic therapy is a promising treatment for cancer. It involves the combination of a photosensitizer and light of an appropriate wavelength (laser source) to cause the destruction of cancer cells. Phthalocynanines ...
Optimization of riboflavin production by fungi on edible oil effluent

Swalaha, Feroz Mahomed (2010)

South African edible oil processing plants produce approximately 3 x 105 tonnes of oil annually with up to 3 tonnes of water for every tonne of oil produced. Wastewater that contains oil extracts varies in organic loading ...
Computational studies of the folding patterns of small and medium-size polypeptides

Mokoena, Paul (2010)

This study involved a series of molecular dynamics (MD) simulations applied to case studies of small and medium-size polypeptides to assess the thermodynamics of their folding characteristics. Peptide folding is a complex ...
Optimisation of HPLC-based methods for the separation and detection of herbicide glyphosate and its major metabolite in water

Madikizela, Lawrence Mzukisi (2010)

Water storage dams play an important part in the collection and purification of water destined for human consumption. However, the nutrient rich silt in these dams promotes rapid growth of aquatic plants which tend to ...
Excess molar volume and isentropic compressibility for binary or ternary ionic liquid systems

Bahadur, Indra (2010)

The thermodynamic properties of mixtures involving ionic liquids (ILs) with alcohols or alkyl acetate or nitromethane at different temperatures were determined. The ILs used were methyl trioctylammonium bis(trifluorome ...
Screening, in-vitro propagation and bioaugmentation of Ceratotheca triloba for the production of secondary metabolites

Mohanlall, Viresh (2010)

Ceratatheca triloba (Bernh.) E. Mey. Ex Hook. f. is one of four species that is common to the summer rainfall areas in South Africa, especially the grasslands. It is used in traditional medicine to treat stomach cramps, ...
Enhanced production of inulinase from Xanthomonas campestris pv. phaseoli

Naidoo, Kameshnee (2010)

Xanthomonas campestris pv phaseoli produced an extracellular endoinulinase on various carbon sources. The highest inulinase production of 9.24 ± 0.03 IU ml¯¹by X. campestris pv. phaseoli was attained using an optimized ...
Strategies to control bacteriophage infection in a threonine bioprocess

Cele, Nolwazi (2009)

Production of numerous biotechnologically-important products such as threonine is based on cultivation of bacterial cultures. Infection of these bacterial cultures by bacteriophages has a detrimental effect in the ...
Excess molar volumes, partial molar volumes and isentropic compressibilities of binary systems (ionic liquid + alkanol)

Sibiya, Precious N. (2009)

The thermodynamic properties of binary liquid mixtures involving ionic liquids (ILs) with alcohols were determined. ILs are an important class of solvents since they are being investigated as environmentally benign solvents, ...
Bioactivity of famine food plants from the family: Amaranthaceae

Singh, Alveera (2009)

Information regarding the nutritional value of wild food plants in Africa and current information varies from source to source. Prior to commercialization of wild foods the nutritional, ethnobotanical, medical, chemical, ...
Expression of a modified xylanase in yeast

Mchunu, Nokuthula Peace (2009)

Protein engineering has provided a key for adapting naturally-occurring enzymes for industrial processes. However, several obstacles have to be overcome after these proteins have been adapted, the main one being finding a ...
Overexpression and partial characterization of a modified fungal xylanase in Escherichia coli

Wakelin, Kyle (2009)

Protein engineering has been a valuable tool in creating enzyme variants that are capable of withstanding the extreme environments of industrial processes. Xylanases are a family of hemicellulolytic enzymes that are used ...
Detection methods of organic acid in steam/water circuits and optimisation using HPLC-UV

Ramrung, Arthi (2009)

This study was mainly a response to a challenge faced by ESKOM in its coal-fired power stations. In spite of using high purity water to drive the turbines, the latter were damaged by ‘pitting’, possibly related to acids ...
Activity coefficients at infinite dilution for ILs : methyltrioctylammonium cation and bis(trifluoromethylsulfonyl)imide or thiosalicylate anions using glc

Gwala, Nobuhle V. (2009)

The activity coefficients at infinite dilution ( γ13 ) were calculated for alkanes, alkenes, cycloalkanes, alkynes, ketones, alcohols and aromatic compounds from gas liquid chromatography (glc) measurements at three ...
Immune modulatory effect of Dichrostachys cinerea, Carpobrotus dimidiatus, Capparis tomentosa and Leonotis leonurus

Hurinanthan, Vashka (2009)

Dichrostachys cinerea, Carpobrotus dimidiatus, Capparis tomentosa and Leonotis leonurus are all plants that are indigenous to South Africa. These plants are used in traditional medicine to treat various ailments. However, ...
Expression of anti-HIV peptides in tobacco cell culture systems

Moodley, Nadine (2009)

Nearly half of all individuals living with HIV worldwide at present are woman and the best current strategy to prevent sexually transmitted HIV is antiretrovirals (ARVs). Microbicides are ARV’s which directly target viral ...
Determination of the heterotrophic and autotrophic active biomass during activated sludge respirometric batch assays using molecular techniques

Ismail, Arshad (2008)

Activated sludge models now in use worldwide for the design and operation of treatment systems use hypothetical concentrations of active organisms. In order to validate and calibrate model outputs, concentrations and ...
Phytoremediation of heavy metals using Amaranthus dubius

Mellem, John Jason (2008)

Phytoremediation is an emerging technology where specially selected and engineered metal-accumulating plants are used for bioremediation. Amaranthus dubius (marog or wild spinach) is a popular nutritious leafy vegetable ...
