Dr Yolandi Swart
Dr Yolandi Swart, who took over from Prof Lynette van der Merwe as the new Director of the Undergraduate Medical Programme (MB ChB programme) in the School of Clinical Medicine within the Faculty of Health Sciences at the University of the Free State (UFS), says she is excited about the new opportunities that come with this position.

The new Director of the Undergraduate Medical Programme (MB ChB programme) in the School of Clinical Medicine within the Faculty of Health Sciences at the University of the Free State (UFS) has a passion for teaching and learning and brings a wealth of experience with her.

Dr Yolandi Swart, who took over from Prof Lynette van der Merwe on 1 March 2022, says she is excited about the new opportunities that this position brings. She was not actively job-hunting and came across the advertisement by accident but was thrilled when she was informed that she is the recommended candidate.

A deep love for the UFS

“I will be heading up an amazing team of people who drive the MB ChB programme, making sure that we walk with our students on their journey to become the next generation of health professionals who will contribute to the health and wellness of our population. Our functions include coordinating the undergraduate curriculum, providing student support, as well as logistic support to ensure the smooth running of the MB ChB programme,” says Dr Swart.

As an alumna of the university (she obtained both her MB ChB and postgraduate MMed in Community Health at the UFS), she has a deep love for the UFS, as it has played a huge role in developing her into the person she is today.

According to Dr Swart, she looks forward to getting to know the students and seeing them develop into the best they can be, as well as engaging with the academic staff as they guide and train the students. She brings a diverse background to the position, having practised as a doctor, specialised in Community Health, and worked in clinical research at various levels, including senior management. This has afforded her the opportunity to equip herself with skills that she hopes will provide support and direction to the Undergraduate Programme Management team in order to provide excellent service in all its functions.

Her vision

“I love teaching and learning – taking a concept and making it accessible to someone.  There are few things as satisfying as seeing that expression that says ‘Oh, now I get it!’

Kovsies has always had a reputation of producing excellent doctors.  “It is my vision to build on that reputation, integrating local and international best practices as they develop into our students’ training, with the aim of developing young professionals who are competent, resilient, and able to face the challenges that life will throw at them – so that they, in turn, can play their role to influence lives for the better.”

Prior to her appointment, she worked at FARMOVS as a clinical research physician for more than six years, the past year and a half as the company’s Medical Director. Says Dr Swart: “I love challenging myself with new things every so often. Past and present hobbies include surfing (which died an early death, as I was horrible at it), scuba diving (yes, with sharks as well), horse-riding, and self-defence.  Most recently, I got hooked on traditional archery – a very challenging skill to try and master.”

Dr Swart says she has learned throughout her personal life and professional career that life sometimes takes unexpected turns – but if one is open to the opportunities afforded by those unexpected turns, it often turns out so much better than the original plan could ever have been. “Difficulties and challenges will always come – but if one faces them with a positive attitude, they teach life skills that you would otherwise never have attained.”

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.
