In a rapidly changing, uncertain and complex world, the role that universities are playing as the engines of social mobility, as drivers of the economy and as generators of new ideas, is now more critical than ever.  Due to the universal nature of knowledge, universities are global in scope – a space that encourages new ideas, controversy, inquiry, and argument and challenges orthodox views, but they are also deeply entrenched in their local environment, influenced by socio-economic and political dynamics.  There is an expectation that universities should exhibit great levels of responsiveness and public accountability, with higher levels of trust in higher education, and between higher education and government, and higher education and the public.  The challenge for both higher education and government is to allow institutional autonomy without oppressive accountability.  

Over the past few years, the purpose of universities has been challenged in relation to their role in society, their advocacy for speaking truth to power, their continuous strive to be great universities without being elitist, and their ability to function in an age of populism. The Trump administration and, more recently, Brexit have demonstrated that there is a decline in the respect for evidence and advice from subject-specific experts.  It seems (as in the case of the Trump administration) as if empirical reality does not matter, nor does empirical reasoning form the basis of public policy – a political place that is becoming increasingly anti-intellectual.  Emotion and personal belief have been shown to carry more weight than objective facts and evidence in terms of influencing public opinion.  Fake news and ‘the alternative truth’ have also challenged the fundamental principles of a university – academic freedom and the generation of new knowledge in the pursuit of truth.

A digitally unequal society
The COVID-19 pandemic has shown deep fault lines in our society – stark poverty and inequality – that universities should engage with (and they do); however, they cannot eliminate it on their own, but can be part of the solution.  South Africa is the most unequal society in the world.  Before the COVID-19 pandemic, the South African economy was already in deep trouble, with sovereign downgrades by all the rating agencies and with an unemployment rate close to 30%.   The national lockdown, in an attempt to ‘flatten the infection curve’ and hence manage the response of the national health system to COVID-19 cases, has added to the pressure on the economy.  It is envisaged that a large number of people (estimated between 3 and 7 million South Africans) will lose their jobs after the national lockdown period, adding to poverty and an already high unemployment rate.  Even during the lockdown period, there are many South Africans living in crowded spaces, hence finding it difficult to practise social distancing, may not have running water and proper sanitation, and possibly do not have regular access to food.  

As schools and the post-school education and training sectors move online with their learning, it further shows how digitally unequal our society really is – access to connectivity, data, and an appropriate digital device is a challenge, and electricity is not evenly distributed or is non-existent in our society.  These institutions, within the environment of digital inequality, are ensuring that digital equity is maintained as far as possible.  Many churches, business leaders, and certain politicians have called for a different social pact between business, labour, and government to address the state of the economy – any such action, however, must be supplemented by concrete measures for social reform.

Regaining trust in universities
But perhaps this pandemic has also created an opportunity for science and evidence to regain credibility in informing government decisions and public trust, and for universities to demonstrate respect for evidence. During the initial stages (early March) of COVID-19 in South Africa, the epidemiologists and virologists have shown through confirmed data from the National Institute of Communicable Diseases (NICD) that South Africa was in the early phase of the infection curve – also interpreted to be the relatively low-risk phase of the curve; this would be the right time to apply the principle of social distancing.  It allowed certain organisations (such as universities) to pro-actively suspend part of their activities so as to minimise the number of people in their operational environment, well before the national lockdown was announced on 26 March – a decision based on science.

Through data and proper analyses, the NICD, other scientific bodies and the Ministerial Advisory Committee on COVID-19 provided evidence-based information to government and the public, from which meaningful decisions could be taken.  The South African government has made it perfectly clear that decisions around COVID-19 will be made based on the science associated with this pandemic – a stance to be applauded.  Hence, the risk-adjusted approach of ‘opening up’ the economy through easing the lockdown measures but constantly monitoring the infection curve is an excellent example of risk management while continuously assessing the risks.

Universities, science laboratories, and pharmaceutical companies around the globe are hard at work to develop an effective vaccine for COVID-19, which is another opportunity to demonstrate how science can assist in protecting people from this terrible virus. Universities are making advances in personal protective equipment (PPE), the development of new technologies for non-ICU provision of oxygen to COVID-19 patients, more advanced methods of testing (for the virus) to reduce turnaround times, and various other scientific studies.  

This platform is giving universities a renewed impetus to use science and scientific developments to advance societal agendas such as climate change, poverty and inequality, public health and social justice (ethics of care) – and more immediate – assisting in re-building a strong South African economy.  It is an opportunity for the public and politicians to regain trust in universities, but it is also an opportunity for universities to profile their public intellectuals so that the value of science and evidence-based output is part of policy debates and informed decision-making.  However, in doing so, universities must strengthen their relationship with society at large, be inquiry-driven, and at the same time be learning and co-creating.

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.
