Heinrich Janse van Vurren_web read more — Heinrich Janse van Rensburg’s is a 5th year medical student from the University of the Free State whose photo was highly commended at the Imperial College London’s Global Creative Competition: Medical Student Responses to COVID-19.

A late-night photo taken through a window at the Pelonomi hospital by a final-year medical student from the University of the Free State (UFS) was highly commended at the first Global Creative Competition: Medical Student Responses to COVID-19.

The competition, held by the Imperial College London, received more than 600 entries from more than 52 countries. The competition was held to bring together the global community of medical students to submit their creative responses to COVID-19 and to provide a platform for them to reflect on their personal and professional experiences during this challenging time.

Medical students from around the world could enter in two categories; visual and literary, and the winners were announced during a Global Awards Ceremony on 14 October.

Meaning behind the photo

Heinrich Janse van Rensburg’s late -night photo highlights the economic inequality that persists in South Africa. The photo was taken from the Pelonomi Hospital which is located in Heidedal, Bloemfontein, and shows the old, forsaken Dutch Reformed church in the foreground, shacks in the background with smoke billowing from the dwellings, where up to six people live in one room trying to stay warm during winter. They are built so close to each other that there can be no talk of effective social distancing.

According to Janse van Rensburg the theme of inequality in the South African milieu is further shown in the striking contrast between light and dark in the picture. “And now, with the COVID-19 pandemic placing a massive burden on an already struggling healthcare system the inequality is even more visible,” says Janse van Rensburg.

A little shocked

He was a little shocked when he heard his photograph was highly commended. Janse van Rensburg says: “Imperial College London is a big institution and being an international competition I did not really expect a lot. There were participants from over 52 countries, and having seen some of the works that were submitted it feels special to be one of the students being noticed.”

Janse van Rensburg, who has never considered doing art, heard about the competition through the Faculty of Health Sciences platforms during lockdown level 5. He saw it as an opportunity to reflect, which has become even more imperative in times like these.

He says he does not go searching for art, but “notices” it from being conscious – something he thinks is important in medicine and life.

Value of creativity in promoting mental well-being

Dr Lynette van der Merwe, undergraduate medical programme director, School of Clinical Medicine, congratulated Janse van Rensburg, saying this commendation in an international competition underscores his talent and the value of creativity in promoting mental well-being.

“Heinrich’s artwork and showcase precisely what we aspire to develop in our exceptional UFS doctors-in-training: a professional with self-awareness, empathy and humanity.

“We initiated a Mental Health Awareness initiative and art competition in the School of Clinical Medicine in 2018 to promote creative expression as a means of supporting students’ mental health. Heinrich has won awards with his creative contributions every year, exhibiting his imaginative ability.”

Surgery and photography

Janse van Rensburg says he has always loved beautiful things and the meaning people attach to art is a good way to communicate that. He has applied for an internship at the Mitchells Plain hospital for when he completes his studies at the end of this year and is thinking of specialising in reconstructive or pediatrics surgery. Besides that, he would like to tap into his creative side and continue with the photography.

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.
