The Southern African Association of Health Educationalists (SAAHE) recently bestowed the Council Medal Award – its highest accolade – on Prof Gert van Zyl, Dean of the Faculty of Health Sciences at the University of the Free State (UFS) in recognition of his extraordinary and sustained contributions to Health Professions Education (HPE) in Southern Africa.

The SAAHE Council Medal is awarded to individuals who have demonstrated long-term, impactful contributions to HPE, transforming pedagogy, advancing equity and diversity, and inspiring excellence in teaching, research, and engagement. Recipients must also demonstrate national and international recognition, as well as exemplary leadership, mentorship, and inclusiveness.

 

A transformative leader in medical education

Prof Van Zyl’s visionary leadership has been pivotal in shaping the future of medical education in South Africa. His strategic role in the development and implementation of the UFS’s five-year MBChB curriculum modernised the teaching and learning experience for medical students, aligning it with international best practice while addressing the specific needs of the South African healthcare context.

Speaking of his award, Prof Van Zyl expressed his gratitude and humility, acknowledging the collective efforts of colleagues, students, and institutional partners over the years. His recognition serves as an inspiration to the HPE community, illustrating the profound and lasting impact that dedicated leadership and innovation can have on the future of healthcare education.

Central to his transformative approach has been the integration of Interprofessional Education (IPE) and Community-Based Education (CBE). These innovative strategies ensured that medical training not only develops technical expertise but also nurtures collaborative practice and community engagement. Prof Van Zyl championed practical learning through CBE initiatives in Trompsburg and Springfontein, later expanding this model to Botshabelo, thereby fostering a strong culture of service to underserved communities.

 

A founding member and lifelong contributor to SAAHE

Prof Van Zyl’s association with SAAHE dates to its very inception in the early 2000s. As a founding member, he was actively involved in the organisation’s transition from the South African Association of Medical Educators (SAAME) to SAAHE, participating in the first meeting in Bloemfontein. His leadership and passion for HPE have been constant in the association’s growth and evolution.

His sustained commitment is evident in his 15 years of service on the SAAHE Executive Committee (2005-2020). Throughout this period he was instrumental in guiding the association’s strategic direction, ensuring that it remained a dynamic platform for advancing medical and health professions education.

Prof Van Zyl’s engagement extended well beyond committee work. He has been a consistent and influential presence at SAAHE conferences, contributing his expertise and thought-leadership at gatherings in 2006, 2007, 2012-2015, 2017-2019, and 2024. His presentations and discussions have enriched the dialogue around pedagogy, curriculum reform, and capacity building in HPE.

 

Advocate for mentorship, inclusivity, and capacity building

At the heart of Prof Van Zyl’s career is a deep commitment to mentorship and capacity development. Colleagues and students alike have benefited from his guidance, which blends academic excellence with a genuine investment in the growth and success of others. His leadership style has consistently promoted inclusivity and equity, fostering an environment in which diverse perspectives and talents can thrive in the service of excellence in HPE.

 

A deserving recognition of a lifetime’s work

The awarding of the SAAHE Council Medal to Prof Van Zyl is a fitting acknowledgment of his decades-long dedication to advancing HPE in Southern Africa. His transformative influence – spanning curriculum innovation, professional development, organisational leadership and community engagement – embodies the qualities the medal seeks to honour.

With this accolade, SAAHE not only honours Prof Van Zyl’s remarkable achievements, but also celebrates a career devoted to building a stronger, more inclusive, and forward-looking HPE landscape in Southern Africa.

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.
