Biolistic-mediated transformation of Eragrostis Curvula with the HSP 12 gene

Author: Ncanana, Sandile Welcome Date: 2003 Eragrostis curvula is a desiccation sensitive monocotyledonous plant and an economically important forage grass in southern Africa. This species has a potential to be improved for drought and salt resistance among other important agronomic ... Read more
Biological conversion of alkanes to dicarboxylic acids : an investigation into process challenges and optimisation in hydrocarbon-based bioprocesses

Author: Williams, Peta Clair Date: 2005 The focus of this project is bioconversion of alkanes to dicarboxylic acids. Dicarboxylic acids are versatile chemical intermediates that can be used in the manufacture of perfumes, polymers, adhesives and antibiotics. The use of a hydrocarbon ... Read more
Characterization of a thermostable amidase and development of a bioreactor process for lactic acid production

Author: Makhongela, Happy Steven Date: 2005 This thesis reports studies of the biochemical properties of a newly isolated thermostable amidase from Bacillus sp. RAPc8, and development of a continuous reactor process for the production of a target product. The amidase was cloned and ... Read more
Conversion of hydrocarbons to biosurfactants : an insight into the bioprocess optimisation of biosurfactant production using alkanes as inducers

Author: Bamara, Prosper Date: 2009 Surfactants are chemical compounds that are able to alter interfacial properties, particularly surface tension. When they are biologically produced, the term biosurfactant is used. One of the most important groups of biosurfactants is a family ... Read more
Energy from waste as a renewable energy supply to supplement electricity in South Africa

Impact of molasses quality on ethyl alcohol fermentation by the yeast saccharomyces cerevisiae

Author: Sibanda, Mkhululi Benedict Date: 2009 The use of blackstrap cane molasses in industrial ethanol production is characterised by fluctuations in fermentation efficiency due to its compositional variation. Crucial to optimisation of ethanol production is thorough knowledge of the ... Read more
An investigation into the bioremediation of black olive brine wastewater

Author: Werner, Craig Michael Date: 2005 In South Africa, the table olive industry is burgeoning and as a consequence, the large volume of fermentation wastewaters that are generated have created environmental concerns, as these wastewaters have the potential to pollute rivers and ... Read more
The Laccase from Micromonospora sp.044 30-1 as a biocatalyst for synthesis of antioxidant compounds

Author: Goodwin, Candice Michelle Date: 2010 Laccases (EC 1.10.3.2) are blue multicopper oxidases that catalyse a single electron oxidation of various phenolic substrates with an associated four-electron reduction of dioxygen to water. The varied uses of laccase as a biocatalyst can be ... Read more
Mathematical modelling of agglomerate scale phenomena in heap bioleaching

Author: Ogbonna, Nneoma Date: 2006 Bioleaching is a naturally occurring process that has been harnessed in metal recovery from low grade ores. The heap bioleaching technique involves complex interactions between chemical reactions, microbial processes and transport processes. ... Read more
Optimising the growth of Cryptococcus species SS1, a potential probiotic for farmed abalone

Author: Van Wyk, Jennifer Caroline Date: 2004 Farmed abalone is a reliable and good quality source of abalone. Cryptococcus species SS1 was isolated from the gut of the South African abalone, Haliotis midae, and has been identified as a potential probiotic for farmed abalone. The ... Read more
Quantification of biomass in a biooxidation system

Author: Moon, Jo-Ann Helen Date: 1996 [PAGE 1 missing] The aim of this study was to investigate and compare various methods to enumerate the number of bacteria in a minerals biooxidation system. In this system most of the bacteria are attached to fine particles of ore and therefore ... Read more
