The University of the Free State (UFS) received recognition for its commitment to student success at the 2024 Achieving the Dream (ATD) conference which celebrated its 20-year anniversary. Simphiwe Kunene, an Education master's student originally from the Qwaqwa campus, was selected to represent South Africa as the first DREAM scholar from Africa as part of the conference.

The Achieving the Dream network of over 300 institutions, which is one of the largest movements in US higher education aims to transform colleges and universities so that students of colour and a lower socio-economic status are supported to earn a degree. The UFS is a leading partner in the Siyaphumelela Network, which has been working for 10 years with ATD to enhance the success of students in South Africa. Prof Francois Strydom, Senior Director at the Centre of Teaching and Learning (CTL), accepted the award on behalf of the institution.

Prof Strydom said that collaboration with the ATD and Siyaphumelela institutions has helped the UFS to develop cutting-edge approaches to “level the playing field” and support Kovsies to earn their undergraduate degrees.

The first African DREAM scholar

Kunene was selected as the first African DREAM scholar from the Siyaphumelela network. To select the DREAM scholar, each Siyaphumelela partner institution nominated one student as a preferred candidate. From the proposed candidates, the DREAM scholar was selected by the South African Institute for Distance Education (Saide) based on the following: demonstrating resilience, academic excellence, and a deep commitment to making a positive difference in universities and personal communities.

He addressed the conference of over 2 000 delegates and shared with them his hopes and dreams. Many members of the South African delegation said Simphiwe did his country proud. He had the following to say about his opportunity to be a DREAM scholar: “Being a DREAM scholar was life changing for me, exposing me to an array of opportunities I never knew were possible and available for me. It was as if, for a moment, the world had stopped to just listen to what I had to say."

The way forward

The UFS will continue its work as a partner of the Siyaphumelela network for the 2024-2026 cycle. The multi-stakeholder project team is focused on enhancing undergraduate students’ time, and to position the UFS as a thought and research leader in the area of student success as part of Vision 130.

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.
