Postdoctoral Fellowship - Yeast nitrogen Metabolism
Deadline: 25 March 2022
New Synthetic Biology Team - Several Positions Available
Deadline: 30 November 2021
We are looking for a capable and energetic PhD student to work on a multidisciplinary project on the microbiome of wheat under Conservation Agriculture. The project will involve high throughput amplicon sequencing and qPCR methods, among others. The project is funded by the NRF, and there is a bursary available, however, preference will be given to students who already have their own bursary. The ideal candidate should have completed a MSc degree in Microbiology, Genetics or Biochemistry or any related field with a strong background in molecular biology. Preference will also be given to South African citizens.
Project Title: Regional microbial signatures in South African and Austrian vineyards
Scope of Research: The project is focused on understanding vineyard microbial ecosystems, in particular the influence of region of origin on the mycobiota of grapes. The postdoctoral candidate will have the opportunity to work on individual research as well as to work within a team (doctoral, masters and Hons level students), and in addition, to gain experience in supervision.
Postdoctoral Research Fellowship (18‐month appointment)
Project Title: Engineering yeast strains for biofuel production
The National Research Foundation has awarded the South African Research Chairs Initiative (SARChI): Biofuels and Other Clean Alternative Fuels to prof. WH (Emile) van Zyl at the Department of Microbiology, Stellenbosch University. The Research Chair focuses on the development of technologies for commercial production of secondgeneration bio-energy from lignocellulosic biomass in South Africa.
Plant biomass-derived bioethanol is regarded as a leading alternative energy source in a fossil fuel dependent energy paradigm. Bioethanol functions as octane enhancer, and can be used to replace up to 15% of petrol. It also acts as a fuel oxygenate in petrol blends allowing more complete combustion and hence, decreased polluting emissions. The departments of Microbiology and Process Engineering at Stellenbosch University, through the South African Research Chair (SARChI) in Biofuels, are at the forefront of South African research to address the shortcomings of plant polysaccharide conversion to bioethanol. Strains of Saccharomyces cerevisiae were engineered to simultaneously hydrolyse plant materials (cellulose and raw starch) and ferment the resulting monosaccharides through the development of enabling technologies such as advanced plant polysaccharides pretreatment and advanced Consolidated Bioprocessing (CBP). Simplification and cost-reduction of the hydrolysis-fermentation process can be further achieved by integrating superior enzymatic hydrolysis and fermentation with more robust yeast into a single unit operation. To achieve this, supportive bioinformatics research dedicated to solving current problems in bioethanol biotechnology, specifically improved industrial performance of yeast strains and improved catalytic efficiency of enzyme hydrolysis, remain key.
