“I would like for students to walk in here and feel comfortable; it doesn’t matter what you identify as – there is a space for you here,” says Dr Munita Dunn-Coetzee, the new Director of Student Counselling and Development.

Dr Munita Dunn-Coetzee has joined the University of the Free State as the new Director of Student Counselling and Development. This is after an eleven-year stay at Stellenbosch University as the Deputy Director of the Centre for Student Structures and Communities, and later as the Director of the Centre for Student Counselling and Development.

Dr Dunn-Coetzee’s role at the UFS

As leader of the department, Dr Dunn-Coetzee sees her role as one in which she is responsible for moving her team forward. “My role is to really look at what the team needs. This is from infrastructure right through to their own personal development, and to making sure that they have what they need to get their jobs done,” she stated. In addition, Dr Dunn-Coetzee’s responsibilities include, “looking at our strategic intent, aligning with what the university wants, being relevant in terms of our service delivery, and connecting enough with the students”. In fact, one of the things she is excited about is learning from the students at the University of the Free State. “The big thing for me is to make contact with students and to engage with them about what is going on at ground level; the one thing I don’t want to be is someone who sits in the office, sends emails, and think I know what’s going on,” she explained.

A commitment to the mental health of UFS students

Although her two predecessors were internal appointments, Dr Dunn-Coetzee argues that being an external appointment allows her to have a fresh perspective. As such, one of her main priorities for the year is looking at student leaders, day residences, residences on campus, and residential heads, and analysing whether they are empowered enough to have conversations about mental-health issues with students. “The one thing that concerns me is that we have been online for two years, and now that we are telling students to come back to campus, it might evoke a level of anxiety in some students,” she explained. Therefore, ensuring that the department is student-centred in everything it does is very important to Dr Dunn-Coetzee. This varies from the way in which students are dealt with, how emails are responded to, and how students are treated when they walk into the Kovsie Health Building.

A long-term vision for the department and the university

Even though she has not been at the University of the Free State for very long, Dr Dunn-Coetzee has some long-term goals that are bound to positively impact both the students and the staff in her department. “I would like to have a research focus within our department; it is very easy to say that we are doing good work and that we have an impact on our students, but we need to have something that proves it,” she said. Therefore, an evidence-based approach is one of the directions she would like to pursue in her department. In addition, Dr Dunn-Coetzee argues that there is a need for a space in which intern psychologists can be trained. “It keeps your current staff on their toes, and it helps you to really play a role in developing psychologists in South Africa,” she expressed. Therefore, opening this space for young psychologists is something she hopes to make a reality in her time at the university. Furthermore, developing her staff and ensuring that they grow their skill set is an important goal she would like to achieve. “My focus is not to have people work here for thirty years; I need to empower them so that they can develop as much as they can. Of course, I love having them here, but in the event that they want to work somewhere else I need to make sure that they are skilled,” she said. Lastly, a goal she is adamant to achieve is to ensure that the service delivery by Student Counselling and Development is of a high standard on all three campuses.

As such, Dr Dunn-Coetzee would like to be viewed by the student community as accessible and approachable. “I would like for students to walk in here and feel comfortable; it doesn’t matter what you identify as – there is a space for you here,” she said.

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.
