Assessment of the physico–chemical and microbiological quality of household water in the Vaalharts irrigation scheme, South Africa
(North-West University, 2012)
Water quality in the Vaalharts region in the Northern Cape Province, South Africa, decreased over the past few years and there was a need for the microbiological and physico-chemical assessment. This problem was identified ...
Characterization of heavy metal tolerant bacterial plasmids isolated from a platinum mine tailings dam
(North-West University, 2012)
The development of metal-tolerance and antibiotic resistance in bacteria may be caused by metals polluting a particular environment. During mining and mineral processing activities, large quantities of metals are deposited ...
Characterization of bacteria isolated from a platinum mine tailings dam
(North-West University, 2012)
Contamination from various sources has a huge impact on soil health and microbial community composition. Metal contamination of soil in mining scenarios is of concern and is not adequately addressed, particularly with ...
Phylogenetic and antibiotic resistance variance amongst mastitis causing E. coli : the key to effective control
(2012)
Environmental pathogens, such as Escherichia coli and Streptococcus uberis, are currently the major cause of mastitis within dairy herds. This leads to severe financial losses, lower production rates and deterioration of ...
Diversity and characteristics of yeasts in water sources of the North West Province
(North-West University, 2012)
Yeasts form an important part of many ecosystems and significantly contribute to biodiversity. However, yeast biodiversity in the North West Province remains largely unexplored. The aim of this study was to determine the ...
Surface water quality of the North West Province based on physico–chemical properties and faecal streptococci levels
(North-West University, 2012)
Water resources in the North West Province are characterised by an overall scarcity due to non–perennial rivers being the dominating water sources. However, increases in water demand from all social, environmental and ...
Diversity of gut–microorganisms in Bt–resistant and Bt–susceptible larvae of the maize stem borer (Busseola fusca) (Lepidoptera : Noctuidae)
(North-West University, 2012)
Maize is one of Africa’s main food sources. It is therefore important to protect this crop
against pests such as the maize stem borer Busseola fusca. Genetically modified Bacillus
thuringiensis (Bt) maize has been shown ...
A PCR detection method for mutations in receptor–protein genes from Busseola fusca potentially involved in Bt–resistance
(North-West University, 2012)
Genetically modified (GM) crops attracted interest globally when use of these crops resulted in significant increases in yield and production. These increases were due to protection of crops from pests, weeds and diseases. ...
Microbial population dynamics during windrow composting of broiler litter
(North-West University, 2012)
South Africa produces an average of 154 million broilers (Gallus gallus domesticus) annually, arising to an estimated 886 million kg of broiler litter. The largest population of broilers are reared in the North West province. ...
