Opinion article by Prof Sethulego Matebesi, Academic Head of Department, Associate Professor: Sociology, University of the Free State .


In Teams of Rivals, author Doris Goodwin notes how former American president Abraham Lincoln created value by surrounding himself with people who have the capacity and the tenacity to challenge him. Despite many of the challenges he faced throughout his presidency, he managed to build a common cause with his cabinet to foster the interests of Americans. In a completely different text, Crisis of Conscience: Whistleblowing in an Age of Fraud, Tom Mueller laments how people fail to act out of apathy, complicity, or fear. 


These two distinct texts raise the question of how leadership should react to criticism and the requisite degree of freedom of speech that public representatives should have. 


Similarly, the back-and-forth saga between Tourism Minister Lindiwe Sisulu and President Cyril Ramaphosa over whether she apologised for her opinion piece that criticised black judges, effectively drills home a longstanding historical lesson. This lesson is that political astuteness is a phenomenon as old as the history of politics itself.

Although the astuteness shown by Sisulu against critics from her political party may be puzzling, her public exchanges that a statement by President Cyril Ramaphosa was a ‘misrepresentation’ of their meeting are more puzzling. 
But why is this puzzling? What are we to do about what some call a show of unprecedented defiance and others assertiveness? We also need to ask whether Sisulu’s stance can be adequately explained by those who label her as being arrogant and who deserve to be fired by President Ramaphosa.

A political travesty to apologise on behalf of Sisulu

Public apologies are a common occurrence globally. They often come by way of assuming guilt, expressing remorse, and admitting responsibility. Thus, proper apology etiquette requires the ‘wrongdoer’ to deliver the apology. However, this was not the case with Minister Sisulu.

Sisulu acted in a very public way with her opinion piece and her response to the ‘apology in her name’ released by the presidency. Certainly, with her experience as a public figure, she was aware of the implications of her actions.

Furthermore, she was consistent with her narrative against criticism directed towards her. Yet, we do not know why the presidency saw the need to apologise on behalf of Sisulu. Perhaps it had unreasonable expectations that Sisulu would publicly accept what she disagreed with privately.

Notwithstanding the sincerity of the presidency in dealing with this matter, supporters of President Ramaphosa will, on the one hand, be disillusioned by this own goal. At the same time, those who support Minister Sisulu may be encouraged by her steadfast refusal to accept a coerced apology used as a shaming mechanism. She inadvertently represents a dynamic articulation of an alternative repertoire of contention within the ANC.

Lately, we have witnessed a surge of nationalism globally during the COVID-19 pandemic. The Economist referred to the narrative battle between China and the United States over the pandemic as a ‘new scold war’, threatening to tear the world apart. But, as this Sino-US relationship reminds us, what is at stake is less the tit-for-tat scold war between Sisulu and Ramaphosa that threatens to spiral out of control, than the subdued attempts to attain constituent support within the ANC.

Sisulu herself has never publicly indicated her availability to contest the presidency of the ANC at its next elective conference. By any measure, if she does have such aspirations, stepping forward and engaging politically is one thing, but open defiance of authority is another. Since there are no permanently privileged constituencies in political malaise created by regeneration projects such as the organisational renewal drive of the ANC, the struggle to articulate and establish the interests of those who are aggrieved within the party is an ongoing process.

But where does this leave President Ramaphosa?

Many commentators have noted that his long game is no longer effective. However, President Ramaphosa wants to upend the notion that robust debates within the structures of the ANC are not tolerated. He is wary of the propensity of ANC structures to support those who are victimised. And while the scold war is in full swing, others will join in trying to win the hearts and minds of ANC members.

Meanwhile, when failure to act decisively in the face of predictable situations facing the country, particularly during a crisis; we can then no longer talk about protecting the interests of South Africans.

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.
