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. ...
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 ...
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 ...
Antibiotic resistant bacteria and -genes in raw water, and the implications for drinking water production
(North-West University (South Africa). Potchefstroom Campus, 2019)
The introduction of antibiotic treatment in the 1940s was a revolutionary breakthrough in medicine. However, the wide and inappropriate use of antibiotics ever since have created the perfect conditions for increasing the ...
Diversity and functional attributes of microorganisms from stockpiled soils of coal mines in Mpumalanga Province, South Africa
(North-West University, 2018)
Coal mining in South Africa is renowned for large-scale removal of topsoil and subsoil through opencast mining. Such processes lead to an enormous amount of land degradation, and thus limit the land when mining operation ...
A molecular study of the causal agent of bacterial leaf streak disease
(North-West University, 2016)
Bacterial leaf streak disease (BLSD) of maize is caused by the pathogen currently classified as Xanthomonas campestris pv. zeae. The disease has only been reported in South Africa and is a potential threat to commercial ...
Antimicrobial resistant bacteria and genes in selected surface water bodies of the North West Province
(North-West University, Potchefstroom Campus, 2017)
It has recently been established that apart from the over or misuse of antibiotics, metal pollution in the natural environment may also contribute to antibiotic resistance even when antibiotics are absent. The Wonderfonteinspruit ...
Influence of vermicompost application on rhizospheric microbial communities and Arbuscular mycorrhizal fungal colonisation of BT and non-BT maize in agricultural soil
(North-West University, Potchefstroom Campus, 2018)
Increasing crop production to ensure future food security while reducing environmental pressure on agro-ecosystems requires improved nutrient and water use efficiency. The soil microbial community directly and/or indirectly ...
Molecular quantification and characterisation of aminoglycoside resistant bacteria and genes from aquatic environments
(North-West University, 2018)
Antibiotic resistance bacteria and antibiotic resistance genes (ARGs) could be disseminated and selected for in the environment, particularly aquatic ecosystems. This is due to the interplay between humans, animals and ...
The effect of cadmium on earthworms (Eisenia andrei) and their intestinal bacteria
(North-West University, 2018)
Cadmium contamination, predominantly from anthropogenic activities such as mining, have a significant impact on soil organisms. It alters the abundance, diversity, community structure, ecological functions and the species ...
