For Dr Katleho Tsilo, one of the latest graduates from the University of the Free State (UFS) Faculty of Health Sciences says graduating from medical school is a dream come true for her and her family.

For Dr Katleho Tsilo, one of the newest graduates from the University of the Free State (UFS) Faculty of Health Sciences, graduating from medical school does not only represent the answered prayers, persistence and sheer grace, it is also a dream come true for her and her family.

Dr Tsilo graduated on Monday 13 December 2021 during the UFS’ year-end graduating ceremonies. 

“It still feels unreal that I was able to overcome the greatest challenge that I was presented with. In my entire medical school career, I have faced many great challenges, from not having any kind of funding at all, to initially not being accepted into medicine to really having to fight for my position each and every semester while also fighting with and for my fellow students in the various leadership positions aforementioned. 

“There were moments of weakness where I wished to just quit it all, but with support from the faculty and my family, I managed to hold on. My dream was and still is bigger that any challenge that I have ever encountered,” says Dr Tsilo. 

Had various leadership positions

During her student years, this Botshabelo native engaged in various leadership positions. She also had to overcome numerous obstacles including the imposter syndrome. According to her, coming from a poor background, with very little resources, she sometimes felt insecure about what she could offer and what she is capable of. Being a health worker during the COVID-19 pandemic was also very challenging because of the uncertainty of everything and how dangerous the work environment in the hospital was proving to be.

“I was privileged enough to be elected as part of the MSA (Medical Students Association) in the Academics portfolio, this is where I then came up with the idea of collecting textbook donations and gifting the less privileged students. I was also elected to be part of the Residence Committee of the new Health Sciences Residence, in the Finance Portfolio.”

Can’t imagine doing anything else

Though she did not always want to study medicine, she ultimately decided on this field as she could not imagine doing anything else. She believes it is a calling, as she always wanted to live a life full of purpose and helping other people. Helping put a smile on someone’s face when they are going through illness is enough to change one’s life, explains Dr Tsilo about her decision to study medicine. She will be doing her internship at the Leratong Hospital in Krugersdorp, Gauteng.

Dr Tsilo, who is hoping to go into Health Science Education or Public Health, says her motivation comes from her family background. “Having been surrounded by poverty for the greater part of my life pushed me to become the difference. I was and still am determined to not be another statistic. Another thing that really motivates me is being of some help to someone. I cannot change the whole world at one time but I can surely start with one person at a time. I believe so much in the power of giving, whether knowledge, time or resources So much that I started my own foundation: the Open Hands Foundation.”

According to Dr Tsilo, her journey to graduating was intimidating – having to adjust to being a student was already tough, however adjusting to being a medical student proved to be a whole new level of challenging. It came with a lot of late nights and very early mornings, months without seeing her family and having almost no luxurious pastimes. 

But she persevered because she always had a goal and was determined to reach it. She had a vision to complete this degree and do it in record time and that’s exactly what she did. “Your vision should always fuel your mission,” says Dr Tsilo. 

Besides medicine, her other passions include charity work – something she has been doing right through her student years. 

Passion for charity work 

“I love charity work and if you did not find me studying, that’s what you would find me, doing. Open Hands is where I exercise this passion. I collect clothes, shoes and food items for the less privileged in our communities.
To students struggling and also facing difficulties, I have this simple message: Don’t stop. Don’t stop working hard, don’t stop hoping and dreaming and if you need help of any kind, it is always available. Know that you are not struggling alone, struggle is part of the journey – it always seems impossible but as long as you don’t stop you will eventually reach your destination.”

Prof Lynette van der Merwe, who took up her new position as Academic Head in the Division Health Sciences Education, Faculty of Health Sciences on 1 December 2021, congratulated the new cohort of UFS doctors and reminded them of the three Cs in the MBChB programme in 2021 – courage, conviction and compassion. She also proposed a new “C” for the year ahead: Character.  

“Character is seen in how you treat those who can do nothing for you. It takes time to develop, and only grows through suffering and failing; no shortcuts, no life hacks here. Character makes you seek to be worth knowing, rather than well known. Adam Grant says: ‘Meaning is about making a difference, not having an audience. Your legacy is not how many footprints you leave.  It’s how long they last.’ Wherever life takes you from here, whatever happens to you or through you, do what is right, not easy. Be a person of value, not success.”

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.
