The degradation of the endocrine disrupting chemical, bisphenol-A : a comparative study between fungal and bacterial laccases
(University of the Western Cape, 2015)
The degradation of endocrine disrupting chemicals (EDCs) is a topic of high importance and one that research efforts are continually being focused on. These harmful chemicals are known to cause adverse health effects in ...
Engineering bacterial magnetic nanoparticles
(University of the Western Cape, 2013)
Magnetosomes, produced by magnetotactic bacteria (MTB), are the most attractive alternative source of non-toxic biocompatible magnetic nanoparticles (MNPs). A magnetosome contains Fe2O4 magnetite with properties superior ...
Synthesis of silver nanoparticles and investigating their antimicrobial effects
(University of the Western Cape, 2015)
Water is essential for life, yet access to safe drinking water is still a major concern worldwide due to waterborne diseases. The current study proposes silver nanoparticles (AgNPs) as an antibacterial agent. Silver ...
The effects of nitric oxide on soybean superoxide dismutase activity during osmotic stress
(University of the Western Cape, 2012)
Nitric oxide (NO) is a signaling molecule involved in mediating plant responses to various biotic and abiotic stresses. Major abiotic stresses (drought, salinity, cold) induce common cellular responses, causing osmotic ...
Identification of biomarkers associated with cervical cancer: a combined in silico and molecular approach
(University of the Western Cape, 2014)
Cervical cancer is the leading cause of cancer mortality among black women in South Africa. It is estimated that this disease kills approximately 8 women in South Africa every day. Cervical cancer is caused by the human ...
Characterisation of a novel soybean candidate glutathione peroxidase/thioredoxin-dependent peroxidase in soybean exposed to osmotic/drought stress
(University of the Western Cape, 2012)
Drought stress is a major contributor to reduced soybean crop yield and quality, this can however be mitigated by the plant’s antioxidant defence mechanisms. One group of antioxidant enzymes that are active in these defence ...
Effects of nitric oxide on novel soybean cystatin gene expression under salt stress in soybean
(University of the Western Cape, 2012)
Nitric oxide (NO) has been shown to orchestrate multiple defense responses to both abiotic and biotic stress. Importantly, elevation of nitric oxide content in plants by using nitric oxide generating compounds has been ...
Characterization of the role of single domain soybean cystatins in regulating drought responses in soybean
(University of the Western Cape, 2015)
This study investigated the effects that drought stress imposed on the growth and development of soybean plants. Soybeans were initially observed at the whole-plant level in order to identify the physical changes that had ...
Development of a reporter system for the analysis of xylophilus ampelinus type III secreted effectors
(University of the Western Cape, 2014)
Xylophilus ampelinus, the causal agent of bacterial blight and canker of grapevines, has long been a threat to the table grape industry in the Western Cape, leading to severe economic losses due to the reduced productivity ...
Barley anther culture: determining the optimal pre-treatment for green plant regeneration
(2013)
Doubled Haploid (DH) Technology is an important tool for plant breeding and
biotechnological applications as it accelerates the breeding cycle of plants by shortening the time required to attain homozygosity. Anther culture ...
