The final webinar of the UFS Thought-Leader Series, presented in collaboration with Vrye Weekblad as part of the Vrystaat Literature Festival’s online initiative, VrySpraak-digitaal took place on Wednesday (2 December). Dr Max du Preez, Editor: Vrye Weekblad (top left) was the facilitator with Ms Magda Wierzycka, Chief Executive Officer: Sygnia Group (top right), Zingiswa Losi, President of the Congress of South African Trade Unions (bottom left) and Prof Ivan Turok, SARChI Research Chair in City-Region Economies at the UFS and Executive Director: Human Sciences Research Council (HSRC), as the other two panelists.

The South African government must ensure that the COVID-19 vaccine is free of charge and that the most vulnerable and exposed in the country receive it first. South Africa cannot afford for anyone not to be immunised.

This is according to Zingiswa Losi, President of the Congress of South African Trade Unions (Cosatu), who was a panellist on Wednesday 2 December at the final webinar of the UFS Thought-Leader Series, presented in collaboration with Vrye Weekblad as part of the Vrystaat Literature Festival’s online initiative, VrySpraak-digitaal. Magda Wierzycka, Chief Executive Officer: Sygnia Group, and Prof Ivan Turok, SARChI Research Chair in City-Region Economies at the UFS and Executive Director: Human Sciences Research Council (HSRC), were the other two panellists.

Progress gives hope

Losi said the news on the health front is hopeful because of the good progress that has been made with regard to developing vaccines for COVID-19. The progress that has been made with the economy also gives her hope.

 “As South Africa we cannot afford to undertake another mass lockdown; our economy, we believe, cannot cope with it. There is not enough available in the UIF or social security to cushion workers any longer. We would face the danger of public rejection if we were to go back to a lockdown.”

According to Losi if the government wants to rebuild the state, it needs to address its internal demons. Says Losi: “It cannot allow corruption and wasteful expenditure to continue to consume 10% of the budget. Bail-outs for state-owned entities are not sustainable. The government also needs to show the necessary will to arrest those who steal, and seize their assets.

“And we are saying the ANC must deal with its demons of corruption, factionalism, and mismanagement of the state. It cannot expect to continue to lead, while it itself is limping. Nor can it continue to take workers’ loyalty for granted. We are looking forward to all of us to be playing a pivotal role in shaping society not only 2021, but in fact in the future of our country,” concluded Losi.

No knight with solutions

Wierzycka says when you look at South Africa and other countries you need to recognise that this crisis is not like the global financial crisis. “This crisis has hit every single country in the world, which basically means that no-one is coming to our help. We are on our own. There is no white knight that's going to arrive with some solution.

“This is where it is so essential that we have some kind of economic policy certainty and political certainty, because the only way that we are going to manage our way through this is to attract foreign investment and job-creating,” said Wierzycka.

Investment in infrastructure is needed as it is the only realistic tool for mass job-creation. Tax breaks and incentives and funding to would-be entrepreneurs or small businesses should be encouraged, said Wierzycka, because those small businesses tend to employ five or 10 people, but these people effectively support 30 to 40 families.

“If it were up to me right now, I would call together the brightest minds in South Africa in a think-tank, completely apolitical, who would sit around a boardroom table designing strategies to get us out of this crisis because no-one is coming to help us.”

Leaders should be held accountable

Prof Turok said looking forward he hopes the local elections will see real choices offered to the electorate, a genuine democratic contest between ideas, different philosophies and different outlooks and different ways of addressing challenges.

“I hope these elections will give us a clear outcome, the civic leaders, I think that's really important. We want our leadership to be held accountable. We want our leadership to stand up and be clear as to what they stand for and be accountable to ordinary people. We want and need a national government to recognise the special important, special claim subsidy as crucibles of progress of social mobility,” said Prof Turok.

He also talked about urbanisation in Africa, saying the continent is the fastest urbanising continent in the world and that a billion more people will be living in cities in 30 years’ time.

According to Prof Turok, we must make sure that South Africa makes a contribution to this. “And that we ensure that this process, this transformation, is a productive one and creates jobs and livelihoods, rather than shantytowns. We've got to see cities as economic drivers. You've got to build on the opportunities of density, of social diversity around the world as critical elements of productivity of investment of innovation, and of economic dynamism.”

African cities, like Johannesburg, and Lagos in Nigeria, should collaborate on joint projects, share expertise to transfer skills, to support each other and to overcome the xenophobia we face in South Africa.

Mushrooms have so many medicinal applications that humans have a substance in hand to promote long healthy lives. And it is not only humans who benefit from these macrofungi growing mostly in dark spaces.

“The substrate applied for growing the mushrooms can be used as animal fodder. Keeping all the medicinal values intact, these are transferred to feed goats as a supplement to their daily diet,” said Prof Bennie Viljoen, researcher in the Department of Microbial, Biochemical and Food Biotechnology at the UFS.

Curiosity and a humble start
“The entire mushroom project started two years ago as a sideline of curiosity to grow edible gourmet mushrooms for my own consumption. I was also intrigued by a friend who ate these mushrooms in their dried form to support his immune system, claiming he never gets sick. The sideline quickly changed when we discovered the interesting world of mushrooms and postgraduate students became involved.

“Since these humble beginnings we have rapidly expanded with the financial help of the Technology Transfer Office to a small enterprise with zero waste,” said Prof Viljoen. The research group also has many collaborators in the industry with full support from a nutraceutical company, an animal feed company and a mushroom growers’ association.

Prof Viljoen and his team’s mushroom research has various aspects.

Growing the tastiest edible mushrooms possible
“We are growing gourmet mushrooms on agricultural waste under controlled environmental conditions to achieve the tastiest edible mushrooms possible. This group of mushrooms is comprised of the King, Pink, Golden, Grey, Blue and Brown Oysters. Other than the research results we have obtained, this part is mainly governed by the postgraduate students running it as a business with the intention to share in the profit from excess mushrooms because they lack research bursaries. The mushrooms are sold to restaurants and food markets at weekends,” said Prof Viljoen.

Natural alternative for the treatment of various ailments
“The second entity of research encompasses the growth and application of medicinal mushrooms. Throughout history, mushrooms have been used as a natural alternative for the treatment of various ailments. Nowadays, macrofungi are known to be a source of bioactive compounds of medicinal value. These include prevention or alleviation of heart disease, inhibition of platelet aggregation, reduction of blood glucose levels, reduction of blood cholesterol and the prevention or alleviation of infections caused by bacterial, viral, fungal and parasitic pathogens. All of these properties can be enjoyed by capsulation of liquid concentrates or dried powdered mushrooms, as we recently confirmed by trial efforts which are defined as mushroom nutriceuticals,” he said.

Their research focuses on six different medicinal genera, each with specific medicinal attributes:
1.    Maitake: the most dominant property exhibited by this specific mushroom is the reduction of blood pressure as well as cholesterol. Other medicinal properties include anticancer, antidiabetic and immunomodulating while it may also improve the health of HIV patients.
2.    The Turkey Tail mushroom is known for its activity against various tumours and viruses as well as its antioxidant properties.
3.    Shiitake mushrooms have antioxidant properties and are capable of lowering blood serum cholesterol (BSC). The mushroom produces a water-soluble polysaccharide, lentinan, considered to be responsible for anticancer, antimicrobial and antitumour properties.
4.    The Grey Oyster mushroom has medicinal properties such as anticholesterol, antidiabetic, antimicrobial, antioxidant, antitumour and immunomodulatory properties.
5.    Recently there has been an increased interest in the Lion’s Mane mushroom which contains nerve growth factors (NGF) and may be applied as a possible treatment of Alzheimer’s disease as this compound seems to have the ability to re-grow and rebuild myelin by stimulating neurons.
6.    Reishi mushrooms are considered to be the mushrooms with the most medicinal properties due to their enhancing health effects such as treatment of cancer, as well as increasing longevity, resistance and recovery from diseases.

Valuable entity for the agricultural sector
Another research focus is the bio-mushroom application phenome, to break down trees growing as encroaching plants. This research is potentially very valuable for the agricultural sector in the areas where Acacia is an encroaching problem. With this process, waste products are upgraded to a usable state. “It is therefore, possible to convert woody biomass with a low digestibility and limited availability of nutrients into high-quality animal fodder. By carefully selecting the right combination of fungus species to ferment agro-wastes, a whole host of advantages could become inherently part of the substrate. Mushrooms could become a biotechnological tool used to ‘inject’ the substrate that will be fed to animals with nutrition and/or medicine as the need and situation dictates,” said Prof Viljoen.
