Research Chairs 2024
Prof Paul Oberholster, Dean: NAS; Dr Glen Taylor, Senior Director for the Directorate Research Development (DRD); Prof Vasu Reddy, Deputy Vice-Chancellor, Research and Internationalisation; and Prof Johan van Niekerk, Vice-Dean for Agriculture in the Faculty of Natural and Agricultural Sciences (NAS); are excited for the new ARC-DALLRD-UFS research chairs.

In a concerted effort to address the challenges and impact of climate change in Southern Africa, the University of the Free State (UFS) together with the Agricultural Research Council (ARC) and the Department of Agriculture, Land Reform and Rural Development (DALRRD) established four new research chairs within the Faculty of Natural and Agricultural Sciences (NAS).

The ARC-DALLRD-UFS research chairs, namely Climate Change and Agriculture, Innovative Agro-processing for Climate-smart Food System, Agriculture Risk Financing and Sustainable Livestock Production, falls under the umbrella of climate change and are part of the established centre of excellence of the ARC and DALRRD on Climate Smart Agriculture.

They will form part of two centres of excellence that the university is also in the process of establishing. The framework for these Agriculture Research Centres of Excellence involves several key components aimed at fostering innovation, collaboration, and impactful research in agriculture. In this case it is Climate Smart Agriculture, enabling them to play a pivotal role in advancing agriculture, enhancing productivity, sustainability, and resilience in the face of global challenges related to climate change.

Prof Johan van Niekerk, Vice-Dean for Agriculture for NAS, and Prof Sonja Venter, from the ARC, are the coordinators for the ARC-UFS-consortium. Joel Mamabolo from the DALRRD is the department’s representative and DALRRD manager in the consortium.

The purpose of the research chairs, he explains, is to conduct high-level research with an aspect of community impact as envisaged in the university’s vision 130. This is the UFS and NAS’s first steps towards creating industry chairs with negotiations between the UFS and the ARC-DALRRD currently taking place for further expansion of the chairs.

Improve research and food security

“The UFS has a long-standing relationship with the ARC and the parties came together to work together to improve research and food security in South Africa and Sub-Saharan Africa. The best way to do this, was by creating research chairs. The ARC saw the university’s expertise in agriculture which also contributed to the ARC establishing the chairs. Our expertise is of such a nature that it does not only influence the sector, but also makes a lasting difference,” says Prof Van Niekerk.

According to him, the ARC and the UFS will collectively manage the research chairs by appointing co-chair principal scientists for each of the chairs in order for the chairs to work together and share resources and expertise. The ARC-DALLRD-UFS research chairs will also work closely together within multidisciplinary research teams and complement each other and in doing so, create a value chain within the agriculture sector.

It will integrate various disciplines including agronomy, genetics, soil science, ecology, pathology economics, socioeconomics horticulture, animal sciences, food sciences and engineering to mention a few. This multidisciplinary approach will foster comprehensive research solutions and innovation at the intersection of different fields and will aim to contribute to sustainable food systems for the future.

The first two chairs; Climate Change and Agriculture, headed by Prof Linus Franke, Head of the UFS Department of Soil, Crop, and Climate Sciences, and the Innovative Agro-processing for Climate-smart Food System, which will be under Dr Alba du Toit, Senior Lecturer in the Department of Sustainable Food Systems and Development, officially started on 1 July 2024, while the remaining two chairs will begin operating in December. The ARC will soon confirm the co-leaders of the various chairs.

The Agriculture Risk Financing research chair will be shared between the Department of Agricultural Economics, within NAS, and the UFS Business School. The Sustainable Livestock Production chair will fall within Prof Frikkie Neser’s Department of Animal Science. To add more credibility, experience and expertise to the ARC-DALLRD-UFS research chairs, Prof Maryke Labuschagne, who is leading the NRF SARChI Chair in Diseases and Quality of Field Crops, has been appointed as mentor.

Prof Vasu Reddy, Deputy Vice-Chancellor, Research and Internationalisation, says: “These chairs mark an exciting opportunity to deepen our understanding of climate change aligned to our expertise in agriculture. The chairs offer us the opportunity to honour and support the leaders who will contribute in powerful ways to the vibrant intellectual life of the faculty, as well as the university, the ARC and DALRRD.

“The chairs also honour the donor whose financial support makes this form of recognition possible. At the UFS we are committed to engaging in global challenges but with a deliberate local focus, energy and drive. I am especially excited that these chairs demonstrate a commitment to the UFS focus on partnerships with industry, communities, the state and other academic and research institutions both nationally and around the world.”

Grateful for the ARC relationship

Through these chairs more collaborators and partners from other universities in the country and globally will be included in the partnership with the aim to bring together internationally renowned scientific experts that will collectively focus to address global challenges and enhance the development of more scientific capacity for the country.

The university, Prof Van Niekerk continues, is grateful for the cooperation and relationship with the ARC and its President and CEO, Dr Litha Magingxa and the executive management team, as well as the DALRRD DG, Mooketsa Ramasodi and the DDG for Agricultural Production, Biosecurity and Natural Resources Management, Dipepeneneng Serage for creating an environment within which the Universities and ARC can collectively contribute towards developing solutions with the DALRRD for key agricultural challenges of the country.

He expressed his gratitude to the Directorate Research Development (DRD) under the leadership of Dr Glen Taylor, for not only their support, but for bringing the parties together and negotiating with the ARC on their behalf. In this regard he wishes to thank Dr Petronella Chaminuka from the ARC as the acting Executive Manager: Research support and coordination for her support, guidance and leadership during the process.

Prof Van Niekerk also thanked Profs Francis Petersen, UFS Vice-Chancellor and Principal, Reddy, and Paul Oberholster, Dean of the Faculty of NAS, for creating the environment and rendering immense support for this programme from the UFS.

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

 

Figure 1. Yeast cells exposed to over-used cooking oil. Wart like protuberances/ outgrowths (WP) is clearly visible on the surfaces of the elongated yeast cells. With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
