The University of the Free State (UFS) is celebrating Youth Month by showcasing the positive influence of the institution on career development. As part of this initiative, we are sharing the stories of UFS alumni who are now working at the university.

Akani Baloyi, Presidential Youth Employment Initiative (PYEI) Intern in the Disaster Management Training and Education Centre for Africa (DiMTEC), shares her UFS journey:

Q: Year of graduation from the UFS:

A: 2016, 2018, and 2023.

Q: Qualification obtained from the UFS:

A: My first qualification was a Bachelor of Social Sciences in Human Societal Dynamics, my second qualification was a Postgraduate Diploma in Disaster Management, and my third qualification was a Master of Disaster Management.

Q: Date of joining the UFS as a staff member:

A: I have had the opportunity of holding multiple positions at the UFS during my postgraduate studies. The first role I took on was in 2019 when I was a Contact Session Assistant in DiMTEC.

Q: Initial job title and current job title:

A: During my master’s studies, I had the opportunity to take on some roles that helped prepare me for the professional world. I worked as a Contact Session Assistant in DiMTEC during the postgraduate diploma and master’s contact sessions, as an Assistant Officer in Student Academic Services, and as a Research Assistant in the Centre for Environmental Management. I am currently employed as a PYEI Intern at UFS-DiMTEC.

Q: How did the UFS prepare you for the professional world?

A: The roles that I took on during my postgraduate studies at the UFS have contributed so much to my personal and professional development. In the role of Contact Session Assistant, I acquired a diverse set of skills, such as strong communication, interacting with the students, understanding their needs, and conveying information clearly. I also learned to listen actively so that I comprehend the students’ concerns, questions, and feedback in order to respond appropriately. I also developed empathy and emotional intelligence, as it is important to understand and respond to the students’ emotions and needs, to ensure that they feel supported and heard. Another important skill that I developed is organisational and time management skills, which are important for managing and handling administrative tasks, and problem-solving skills that have enabled me to address challenges that arose during the sessions.

In my role as an Assistant Officer, I developed strong communication and interpersonal skills through interactions with students and colleagues, and my customer service skills were cultivated by providing support and information to students. I also learned to pay attention to detail and confidentiality, as these skills are important when handling student records.

in the role of Research Assistant, I worked with a diverse group of people on the Summer School Project, a collaboration between the UFS, the Cape Peninsula University of Technology, and the Technical University of Dresden (Germany). I had the opportunity to be part of a great team of individuals who successfully organised and hosted an online Summer School in 2022 with the theme ‘Monitoring Surface Water Quality: General Framework, Tools and Implementing Disaster Management Aspects in Urban Areas’.

Being a student at the UFS has equipped me with specialised knowledge, critical thinking abilities, and problem-solving skills. By managing multiple responsibilities, I have learned valuable skills such as time management and organisational skills. It also provided me with networking opportunities, which have allowed me the opportunity to build connections with professionals in my field. Being a student at the UFS has facilitated my personal development, as I am now confident in myself and can easily adapt to the everyday challenges of the professional world.

Q: What are your thoughts on transitioning from a UFS alumnus to a staff member?

A: Transitioning from student to staff has been a journey filled with so many feelings. Initially, it was both exciting and scary, as I was uncertain about my new responsibilities and capabilities. However, the familiarity and comfort of the UFS brought ease to this transition. I appreciate the opportunity to continue learning and growing.

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.
