UFS celebrates excellence through its research hubs
The university considers its research chairs and the possibility of future chairs as an integral and strategic initiative to increase its national and international standing through excellent academic and research leadership.

The University of the Free State (UFS) is proud of its research leaders. As of 2018 the UFS has 156 NRF-rated researchers and five Sarchi Research Chairs. These chairs are designed to attract and retain excellence in research and innovation at South African public universities.

Getting the better of vector borne and zoonotic viruses

Prof Felicity Burt leads the Vector Borne and Zoonotic Virus Research Group in the Department of Medical Microbiology and Virology at the UFS. She was awarded a Research Chair to, among others, investigate medically significant vector-borne and zoonotic viruses currently circulating - mainly viruses transmitted by mosquitos and ticks, and viruses transmitted from animals to humans. 

“Years ago, no one knew what Ebola was. One outbreak later, backed by many media reports, and it is almost a household name. The same goes for the recent Zika virus outbreak in South America,” she explains the public’s interest and fears. To prevent the spread of vector-borne viruses to new areas, surveillance and awareness is important. Here in Bloemfontein, Prof Burt and her team are establishing surveillance programmes.

Why research on fungal infections?

“Many diseases no longer pose a threat to humans and life expectancy is prolonged. However, this has also caused an increase in various opportunistic infections, and most of all, fungal infections,” says Prof Carlien Pohl-Albertyn, who is heading the Research Chair for Pathogenic Yeasts in the Department of Microbial, Biochemical and Food Biotechnology. And the rise in resistance to antifungal treatments requires research into pathobiology, including new drug and treatment options. 

Activities of the Research Chair in Pathogenic Yeasts builds on existing research strengths and will contribute towards understanding pathobiology of medically significant pathogenic yeasts belonging to the genera Candida and Cryptococcus. 

Understanding higher education for more equality and justice

Prof Melanie Walker, from the Centre for Research on Higher Education and Development (CRHED) does research on higher education, inequalities and social justice, and how, or if, universities foster the human capabilities and aspirations of students. Does higher education make a difference to the lives of students, their families and communities? 

Prof Walker says the Research Chair on Higher Education and Human Development looks at issues of access, participation and transitions into work, as well as gender, race and social class. They use both quantitative and qualitative methods and includes a strand of participatory research projects with students. Ultimately, the research must contribute to debates, policy and practices in higher education, and a scholarly knowledge base.

Reduced emissions make for a better world

Prof Hendrik Swart chairs the research project that looks into low-energy lighting, using phosphor materials for light emitting diodes (LEDs). The Research Chair on Solid State Luminescent and Advanced Materials is situated at the Department of Physics

The research mainly focuses on better light emission of phosphor powers in LEDs.  According to Prof Swart, the long-term benefit of the research will result in more environmentally friendly devices which use less energy, are brighter and give a wider viewing field. Over the next five years they will develop and produce devices that emit better light using the substances already developed. “We need to make small devices to see if they are better than those we already have,” he says. 

Solutions to food insecurity
 

The Department of Plant Sciences’s research project dives into disease resistance and quality in field crops. Heading this Research Chair is Prof Maryke Labuschagne who focuses on crop quality breeding and disease resistance in field crops. 

Her, and her students’ research focuses on the genetic improvement of food security crops in Africa, including such staples as maize and cassava. “These crops are genetically improved for yield, drought tolerance, disease, and insect resistance, as well nutritional value,” she says. Her disease resistance research will focus on crop protein quantity and quality as well as iron, zinc, and beta-carotene biofortification of staple crops such as wheat, maize and cassava. The disease resistance-breeding project will be a continuation of the internationally acclaimed wheat rust research. 

The university considers the research chairs and the possibility of future chairs as an integral and strategic initiative to increase its national and international standing through excellent academic and research leadership.

Research on cactus pear grabs attention of food, cosmetic and medical industry

The dedicated research and development programme at the UFS on spineless cactus pear (Opuntia ficus-indica) – also known as prickly pear – has grown steadily in both vision and dimension during the past 15 years. Formal cactus pear research at the UFS started with the formation of the Prickly Pear Working Group (PPWG) in June 2002. It has since gone from strength to strength with several MSc dissertations and a PhD thesis as well as popular and scientific publications flowing from this initiative.

According to Prof Wijnand Swart from the Department of Plant Sciences, the UFS is today recognised as a leading institution in the world conducting multi-disciplinary research on spineless cactus pear.

Cactus pear for animal feed

Increasing demands on already scarce water resources in South Africa require alternative sources of animal feed – specifically crops that are more efficient users of water. One alternative with the potential for widespread production is spineless cactus pear. It is 1.14 x more efficient in its use of water than Old man saltbush, 2.8 x more efficient than wheat, 3.75 x more efficient than lucerne and 7.5 x more efficient than rangeland vegetation.

“Studies on the use of sun-dried cactus pear cladodes suggest that it has the potential to provide some 25% of the basic feed resources required by South Africa’s commercial ruminant feed manufacturing sector,” says Prof HO de Waal of the Department of Animal, Wildlife and Grassland Sciences at the UFS.

Until recently, research has focused extensively on the use of cactus pear as drought fodder. However, this is now beginning to shift, with growing interest in the intensive production of spineless cactus pear for other types of animal feed. One example is the spineless cactus pear fruit, produced seasonal, yielding large quantities of fruit in a relatively short period of a few months in summer. Unless kept in cold storage, the fruit cannot be stored for a long period. Therefore, a procedure was developed to combine large volumes of mashed cactus pear fruit with dry hay and straw and preserve it for longer periods as high moisture livestock feed, kuilmoes – a high water content livestock feed similar to silage.

Cactus pear for human consumption

“In addition to its use as a livestock feed, cactus pear is increasingly being cultivated for human consumption. Although the plant can be consumed fresh as a juice or vegetable, significant value can be added through processing. This potential is considerable: the plant can be pickled; preserved as a jam or marmalade; or dried and milled to produce baking flour. It can also serve as a replacement of egg and fat in mayonnaise,” said Dr Maryna de Wit from the Department of Microbial, Biochemical and Food Biotechnology.

The extraction of mucilage from fresh cladodes can form a gelling, emulsifier, and fat-replacing agent commonly found in food products such as mayonnaise and candy. During an information session to the media Dr De Wit and her team conducted a food demonstration to showcase the use of the cladodes in a juice, chicken stir-fry, biscuits and a salad.

The extrusion of cactus pear seed oil provides a further lucrative niche product to the array of uses. These include high-value organic oil for the cosmetic sector, such as soap, hair gel and sun screens.

The cladodes and the fruit also have medicinal uses. It has anti-viral, anti-inflammatory, pain killing and anti-diabetic agents. It is also high in fibre and can lower cholesterol. The fruit also prevents proliferation of cells and suppresses tumour growth and can even help to reduce a hangover.

In South Africa the outdated perception of cactus pears as thorny, alien invaders, is rapidly disappearing. Instead, farmers now recognise that cactus pear can play a vital role as a high yielding, water-efficient, multi-use crop, said Prof de Waal and the members of the Cactus Pear Team.
