The University of the Free State (UFS) is proud to announce that Dr Rosaline Sebolao, our Teaching and Learning Manager in the Faculty of The Humanities, has been recognised with an award from Higher Education Resource Services South Africa (HERS-SA). At the ceremony, Dr Sebolao was one of the top five finalists for her exceptional contributions to higher education, particularly in academic administration.

The HERS-SA Award celebrates outstanding women in academic administration, acknowledging their crucial role in supporting and transforming the higher education landscape. According to Dr Sebolao, “The significance of this award lies in its developmental and transformative impact.” She explains that it highlights the essential contributions made by women in academic administration and encourages gender transformation within universities. This recognition empowers women to take on leadership roles, shifting the focus beyond traditional academic achievements.

Award recipients are selected based on a minimum of five years of demonstrated leadership in academic administration. Dr Sebolao’s innovative leadership practices, her contributions to institutional performance, her peer mentoring, and community engagement were all key criteria in her selection. Her mentoring efforts, particularly through school visits and support for underprivileged students, have made a lasting impact on the community and her peers.

Reflecting on the honour of receiving the award, Dr Sebolao describes it as “humbling and exciting”. She felt especially inspired as a mentor, noting that this recognition has the potential to encourage young women and men to strive for excellence in their academic and administrative pursuits.

Achievements leading to the award

In her role as Teaching and Learning Manager, Dr Sebolao has made significant contributions to both students and academics at the UFS. She has initiated several impactful projects, including the establishment of student indabas and entrepreneurial initiatives aimed at addressing graduate unemployment. Her commitment to improving communication led to the launch of a faculty newsletter, enhancing engagement among academics.

Among her most notable achievements is the Scholarship of Teaching and Learning (SoTL) project, which culminated in the UFS’ inaugural SoTL seminar in July 2024. She also spearheaded the Humanities Excellence Awards, encouraging faculty to pursue greater academic and research recognition. Her dedication to engaged scholarship extended beyond the university, resulting in community collaborations such as the establishment of a school library in Ikgomotseng, promoting literacy and education among local learners.

Dr Sebolao’s academic journey began after transitioning from the business sector to academia in 2013. Her experience in roles such as Peer Mentorship Coordinator and Teaching and Learning Coordinator at the Central University of Technology, and later as Manager of Special Projects in Teaching and Learning, helped shape her leadership style. She joined the UFS during the challenging COVID-19 period, a time that also marked some of her greatest achievements.

One of the key challenges that Dr Sebolao faced was overcoming the isolated nature of work within the faculty. By fostering a collaborative culture, she succeeded in promoting teamwork and innovation across departments. This approach not only improved institutional collaboration, but also strengthened her professional impact.

Dr Sebolao’s relationship with HERS-SA has been instrumental in her development as a leader in higher education. Since participating in the HERS-SA Academy in 2018, she has connected with influential women in the sector and solidified her commitment to mentoring others. Winning this award affirms the importance of mentoring and paves the way for future leaders in higher education.

Looking to the future, Dr Sebolao aspires to continue championing gender transformation in leadership. She aims to empower more women, particularly black women, to take on leadership roles within academia. Her focus is on fostering community development through collaborative projects that promote sustainable living, aligning with her broader vision for teaching and learning at the UFS.

Dr Sebolao encourages young women to believe in their abilities and seek mentorship for guidance and support. She emphasises that perseverance, coupled with a strong support network, is essential to achieving leadership success in higher education.

Outside of her professional life, Dr Sebolao draws motivation from her family and community work. Guided by Ecclesiastes 9:10, which emphasises dedication in all endeavours, and inspired by Mahatma Gandhi’s words, “Be the change you want to see in the world,” she remains committed to leading with passion and integrity.

The UFS community is incredibly proud of Dr Sebolao’s achievement and her continuous contributions to academic excellence and gender transformation in higher education. This award is a testament to her tireless efforts and dedication to empowering others.

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.
