AtNOGC1 protein bioelectrode for the determination of stress signalling molecules - Nitric Oxide (NO), Carbon Monoxide (CO) and Calcium ion (Ca2+)
(University of the Western Cape, 2018)It has been estimated that the world population will reach about 10 billion by the year 2050 and in order to accommodate the increased demand of food, the world agricultural production needs to rise by 70 % in the year ... -
Bacteriophage diversity in haloalkaline environments
(University of the Western Cape, 2013)There are limited reports on virus population in haloalkaline environments; therefore the aim of this study was to investigate the genetic diversity and biology of bacteriophage communities in these environments. Bacteria ... -
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 ... -
Bioactive actinobacteria associated with two South African medicinal plants, Aloe ferox and Sutherlandia frutescens
(University of Western Cape, 2021)Actinobacteria, a Gram-positive phylum of bacteria found in both terrestrial and aquatic environments, are well-known producers of antibiotics and other bioactive compounds. The isolation of actinobacteria from unique ... -
Bioactivity and genome guided isolation of a novel antimicrobial protein from Thalassomonas viridans
(University of the Western Cape, 2019)The continued emergence of bacterial resistance to the antibiotics currently employed to treat several diseases has added to the urgency to discover and develop novel antibiotics. It is well established that natural products ... -
A biochemical and proteomic analysis of sugargraze sorghum under hyperosmotic stress
(University of the Western Cape, 2015)Sugargraze is a moderately drought tolerant sweet sorghum hybrid which is ideal for grazing, winter stand over and pit silage. A major advantage that Sugargraze has over other forages is its very high sugar content which ... -
Biochemical characterisation of an alpha-amylase with pullulan hydrolase type III characteristics derived from a hot spring metagenomics library
(University of the Western Cape, 2024)The field of metagenomics has provided biotechnological researchers with new enzymes and insight into previously unknown enzyme families with potential for novel modes of action and being able to function under extreme ... -
Biochemical characterization of β-xylosidase and β-glucosidase isolated from a thermophilic horse manure metagenomic library
(University of the Western Cape, 2020)The complete degradation of recalcitrant lignocellulose biomass into value-added products requires the efficient and synergistic action of lignocellulose degrading enzymes. This has resulted in a need for the discovery of ... -
Biocontrol potential of fungal endophytes against Fusarium proliferatum in maize
(University of the Western Cape, 2022)Fusarium proliferatum is a fungal pathogen that is the cause of numerous diseases in various crops of fruit and vegetables. About 25% of the maize crops harvested annually are affected by mycotoxins produced by F. ... -
Biodiscovery of Novel Bioactivities from the South African Marine Environment
(University of the Western Cape, 2016)There is currently a global health crisis taking place, which is the increasing occurrence of drug-resistant pathogens within clinical microorganisms. Drugresistant pathogens are increasingly becoming more difficult to ... -
Biogenic synthesis of gold nanoparticles using red and green pear fruit extracts
(University of the Western Cape, 2019)There has been a growing interest in the design of biocompatible and environmentally affable nanoparticles (NPs) among scientists to develop novel and safe biomaterials for use in various biomedical applications. This can ... -
Biological and enzymatic activity of actinobacteria associated with aloe ferox
(University of the Western Cape, 2023)Antimicrobial resistance is a global crisis that has been on the rise for decades, threatening the health and safety of many nations. This highlights the need to discover novel antimicrobial compounds to combat already ... -
Biological approach to improving the evaporation rates of mine wastewater desalination brine treated in evaporation ponds
(University of the Western Cape, 2021)The disposal of brine effluent from inland wastewater desalination plants is a growing global problem with adverse economic and environmental implications because of the substantial cost associated with its disposal and ... -
Bioprospecting for bioactive polysaccharides from marine algae endemic to South Africa
(University of the Western Cape, 2016)Fucoidan is a marine-derived sulphated polysaccharide with bioactive properties ideal for the food, chemical and pharmaceutical industries. The polysaccharide consists largely of L-fucose, has a highly heterogeneous structure ... -
Biosurfactant screening through metagenomic and culture-based approaches
(University of the Western Cape, 2022)The biosurfactant market is still predominantly represented by the three main products: surfactin, sophorolipids, and rhamnolipids, mainly as a result of the high cost and low yield associated with biosurfactant production. ... -
The C-economy, nutritional benefits and symbiotic performance of dual inoculated Phaseolus vulgaris (L.) plants, under variable nutrient conditions
(University of the Western Cape, 2010)The tripartite symbiosis between Phaseolus vulgaris, arbuscular-mycorrhiza and the nodule bacteria, Rhizobia have been the focus of many studies ranging over a number of decades, however these studies have failed to answer ... -
Characterisation of a DNA ligase from an Antarctic metagenomic library
(University of the Western Cape, 2011)A metagenomic gene library prepared from soil found beneath a mummified seal carcass in the Miers Valley, Antarctica, suggests an environment rich in uncharacterised biodiversity including enzymes with possible application ... -
Characterisation of a lignocellulosic degrading bacillus strain isolated from thermophilic compost
