Dr Lindie von Maltitz spoke at DESTEA’s Free State Investment Conference (27 February), which was hosted on the UFS Bloemfontein Campus. In her presentation, she highlighted, among other points, the advantages of the UFS as a strategic partner in the agricultural sector.

Dr Lindie von Maltitz, a Lecturer in the Department of Agricultural Economics at the University of the Free State (UFS), contributed to the programme of the Free State Investment Conference (27 February), which was presented by the Department of Economic, Small Business Development, Tourism, and Environmental Affairs (DESTEA).

The primary objective of the conference, held in the Centenary Complex on the UFS Bloemfontein Campus, was to promote the province as an investment destination of choice and to showcase strategic investment projects across different municipalities. Additionally, the conference sought to connect local businesses with local and international investors and opportunities.

Representatives from financial institutions, academic institutions, national and provincial government departments, chambers of commerce, corporates, investors, and embassies attended the conference, which was opened by Councillor Gregory Nthatisi, the Executive Mayor of the Mangaung Metropolitan Municipality. The honourable Mxolisi Dukwana, the Premier of the Free State, delivered the keynote address.

The sectors covered by the presentations at this conference included mining and gas extraction, transport and logistics, energy, infrastructure, tourism, and the agriculture and agro-processing sector. Dr Von Maltitz’s presentation, ‘Required investment to improve the performance of the agricultural sector in the Free State’, focused on the latter sector.

Representing the UFS in the session ‘Driving Inclusive Growth and Food Security: Agriculture’ – Dr Von Maltitz first focused on what agriculture in the Free State entails, and how it relates to the rest of the country. She then provided a brief overview of the role and importance of agriculture in the South African and Free State economy, adding to that the advantages that investment in the agricultural sector in the Free State will bring.

Numerous possibilities for investment in the sector

According to Dr Von Maltitz, the agricultural sector in the Free State is of vital importance to its economy. “Our income from agriculture and its related industries is the second largest in the country, after the Western Cape. There are numerous possibilities for investment in the sector, not limited to production, but expanded to the entire agricultural value chain. Connecting with the right strategic partners can ensure the success of investment projects. The UFS can contribute as a strategic partner, bringing knowledge, expertise, research, and local and global networking to the table,” she stated.

The importance of investing in the agricultural sector, according to Dr Von Maltitz, is linked to two of South Africa’s biggest challenges: unemployment and poverty. “Investing in agriculture addresses both of these issues. Jobs are created for both unskilled and skilled labour while producing and processing food. The higher agricultural investment is on the agenda, the better for economic growth in our province and country,” said Dr Von Maltitz.

"With food security for a global population that has expanded from 2,5 billion in 1950 to 7,9 billion in 2021, agriculture and its related industries are the sector that will remain important until time immemorial,” remarked Dr Von Maltitz.

She is of the opinion that the Free State presents many opportunities for this sector. Dr Von Maltitz believes there are very few agricultural products that cannot be produced in the Free State. “For example, fruit produced in our province is market-ready before that of the Western Cape. This allows us to access local and international markets early, when prices are higher due to a supply shortage. Because we have cold temperatures in winter, our area has fewer livestock diseases than those found in other parts of the country,” she added.

“Assured by a supportive policy environment, functional infrastructure, and expert knowledge base, investors can be encouraged to invest in the agricultural sector in the Free State,” said Dr Von Maltitz.

In the Free State, however, the development of the agricultural sector is facing several challenges. In her view, failing infrastructure and load shedding are the biggest problems. “Our roads are among the worst in the country, making timely access to markets more difficult. Load shedding has an enormous impact on any processing facility. Climate change is something we need to incorporate into our planning process, continuously developing new risk management strategies for the sector,” she elaborated.

Advantages of the UFS as a strategic partner

She stated that the Free State is an agricultural hub open to many more possibilities. “Speaking as a representative of the UFS, I want to highlight the advantages for investors of the UFS as a strategic partner. Our Faculty of Natural and Agricultural Sciences is one of the best in the country and offers knowledge, skills, and expertise in every field related to agriculture, including soil scientists, animal scientists, climate scientists, crop scientists, wildlife and grassland scientists, plant breeders and pathologists, agronomists, agrometeorologists, and agricultural economists. The value we offer can be attractive to investors who will be reassured by our competence, as supported in the university’s Vision130, which defines our values, namely excellence, innovation and impact, accountability, care, social justice, and sustainability,” Dr Von Maltitz said.

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.

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.
