Africa Month celebration on the UFS South Campus
Attending the Africa Month celebrations on the UFS South Campus were, from the left: Temba Hlasho, Executive Director: Student Affairs; Thandeka Mosholi, Head: Social Responsibility, Enterprise, and Community Engagement; Prof Colin Chasi; Ms Zola Thamae; Prof Francis Petersen; Simphiwe Dube, South Campus SRC President; Dr Cornelius Hagenmeier, Director: Office for International Affairs; Poloko Masuelele; Nombulelo Shange, Lecturer in Sociology; and Bulelwa Moikwatlhai (seated), Office for International Affairs.

Amid great fanfare, colour, and song, the South Campus of the University of the Free State (UFS) kicked off Africa Month in celebration of education on the African continent.

Delivering welcoming remarks on behalf of Dr Marinkie Madiope – the South Campus Principal – was Poloko Masuelele, Assistant Director heading the Curriculum Design and Development Unit on the South Campus. “The African continent is suffering a great deal of challenges, including the scourges of malnutrition and strained delivery of basic education. How revolutionary would it be if we could simultaneously eradicate these vices by formulating policies, mechanisms, and vehicles that would enable us to feed, heal, and teach our people? It is incumbent on us as thought leaders to take the lead in this significant enterprise.”

Bringing a government prospect, was Ms Zola Thamae, the Acting Director in the Free State Department of Sport, Arts, Culture and Recreation. She stated that there is much that could be done to address challenges in Africa if the university and government take hands. She also urged students to read and educate themselves in order to change their background. 

Searching for African solutions

Prof Francis Petersen, Rector and Vice-Chancellor of the UFS, delivered the keynote address. Focusing on the theme of Africa Month, he said when it comes to educational development, there is no other continent that has faced the same trials and challenges as ours. “But in the harsh crucible of history, character, tenacity, and a sense of ubuntu were forged, translating into an exciting, fertile breeding ground for new knowledge creation, independent thought, and innovation,” he added. 

He quoted Paul Kagame, President of Rwanda, who said, “Africa’s story has been written by others; we need to own our problems and solutions and write our own story,” and added that over the past few decades, on many fronts and in many spheres – also in education – this is exactly what has been happening.

“We are actively searching for African solutions to African problems. The value we can offer is substantial,” he said.

Prof Petersen expressed confidence not only in Africa’s people, but also in what they are bringing to the table. “While Africa has established itself as an attractive investment destination, it is now more sought after for its people than for its physical assets. And its people have been driving exciting and encouraging developments in education.”

“In terms of Africa’s contribution to global knowledge, the world is slowly but surely acknowledging the abundant evidence of scientific innovation contributed by African scholars – not only at present, but since the earliest times.”

He also trusts that Africans have advanced considerably in decolonialising curricula. “Across our continent, African history, achievements, and discoveries have been absorbed into school curriculums, replacing a Eurocentric focus in education, and fulfilling the vision of Africans owning their own story. Most higher education institutions – the UFS included – have over the past decade or two also been engaged in a comprehensive, systematic process of decolonising our curricula – incorporating the knowledge created on our own continent in various study fields.”

Despite these encouraging milestones that education has reached in Africa, Prof Petersen is of the opinion that much remains to be done. “As custodians of higher education in Africa, and as part of the larger education sector, we have our work cut out for us,” he stated.

He believes that the unique point in time in which Africa finds itself presents an opportunity to completely reimagine the entire education landscape.

Collectively we will succeed

Also contributing some valuable input to the celebratory event, was Prof Lynette Jacobs, Associate Professor in the Department of Open and Distance Learning. She stated that one of the problems of colonial education is that it does not cultivate African self-esteem. Quoting President Julius Nyerere, she shared that “Education should not alienate students from their traditions but should rather make them appreciate themselves as Africans.” 

According to her, Africans have lost the confidence to celebrate themselves in their African cultures and traditions within the formal education environment.

“Collectiveness, togetherness, dialogue, and being authentically human are what Africa brings to the world. The world has so much to learn from Africa,” she said and asked the audience, “Do you embrace who you are and are you proud to share it with the rest of the world?”

Representing the Unit for Institutional Change and Social Justice was Prof Colin Chasi. He emphasised the importance of working together to bring about positive change in Africa. “We enhance our capacity if we are working together. Collectively we will succeed; separately we will suffer a terrible fate,” he stated.

Researcher part of project aimed at producing third-generation biofuels from microalgae in Germany

A researcher from the University of the Free State (UFS), Prof Johan Grobbelaar, was invited to join a group of scientists recently at the Institute for Bio- and Geo-Sciences of the Research Centre Jülich, in Germany, where microalgae are used for lipid (oil) production, and then converted to kerosene for the aviation industry.

The project is probably the first of its kind to address bio-fuel production from microalgae on such a large scale.  

“The potential of algae as a fuel source is undisputed, because it was these photoautotrophic micro-organisms that were fixing sunlight energy into lipids for millions of years, generating the petroleum reserves that modern human civilisation uses today.  However, these reserves are finite, so the challenge is marrying biology with technology to produce economically-competitive fuels without harming the environment and compromising our food security.  The fundamental ability that microalgae have to produce energy-rich biomass from CO2, nutrients, and sunlight through photosynthesis for biofuels, is commonly referred to as the Third-Generation Biofuels (3G),” said Prof Grobbelaar.

The key compounds used for bio-diesel and kerosene production are the lipids and, more particularly, the triacylglyserols commonly referred to as TAGs.  These lipids, once extracted, need to be trans-esterified for biodiesel, while a further “cracking” step is required to produce kerosene.  Microalgae can store energy as lipids and/or carbohydrates. However, for biofuels, microalgae with high TAG contents are required.  A number of such algae have been isolated, and lipid contents of up to 60% have been achieved.

According to Prof Grobbelaar, the challenge is large-scale, high-volume production, since it is easy to manipulate growth conditions in the laboratory for experimental purposes.  

The AUFWIND project (AUFWIND, a German term for up-current, or new impetus) in Germany consists of three different commercially-available photobioreactor types, which are being compared for lipid production.

The photobioreactors each occupies 500 m2 of land surface area, are situated next to one another, and can be monitored continuously.  The three systems are from Novagreen, IGV, and Phytolutions.  The Novagreen photobioreactor is housed in a glass house, and consist of interconnected vertical plastic tubes roughly 150 mm in diameter. The Phytolutions system is outdoors, and consists of curtains of vertical plastic tubes with a diameter of about 90 mm.  The most ambitious photobioreactor is from IGV, and consists of horizontally-layered nets housed in a plastic growth hall, where the algae are sprayed over the nets, and allowed to grow while dripping from one net to the next.

Prof Grobbelaar’s main task was to manipulate growth conditions in such a way that the microalgae converted their stored energy into lipids, and to establish protocols to run the various photobioreactors. This was accomplished in just over two months of intensive experimentation, and included modifications to the designs of the photobioreactors, the microalgal strain selection, and the replacement of the nutrient broth with a so-called balanced one.

Prof Grobbelaar has no illusions regarding the economic feasibility of the project.  However, with continued research, optimisation, and utilisation of waste resources, it is highly likely that the first long-haul flights using microalgal-derived kerosene will be possible in the not-too-distant future.

Prof Grobbelaar from the Department of Plant Sciences, although partly retired, still serves on the editorial boards of several journals. He is also involved with the examining of PhDs, many of them from abroad.  In addition, he assisted the Technology Innovation Agency of South Africa in the formulation of an algae-biotechnology and training centre.  “The chances are good that such a centre will be established in Upington, in the Northern Cape,” Prof Grobbelaar said.
