Ebeth Grobbelaar is a Scientific Manager in the South African Doping Control Laboratory (SADoCoL) who is responsible for the review and approval of results at SADoCoL, to ensure compliance with the technical requirements of the World Anti-Doping Agency (WADA).

For Ebeth Grobbelaar, Scientific Manager in the South African Doping Control Laboratory (SADoCoL) – which is housed by the University of the Free State (UFS) – her work at the laboratory is profound, as fairness on and off the playing field is vital to her.

“Creating a fair playing field for athletes to compete carries a heavy responsibility, as an anti-doping violation impacts the athlete’s career,” says Grobbelaar, who is responsible for the review and approval of results at SADoCoL to ensure compliance with the technical requirements of the World Anti-Doping Agency (WADA).

Women are the cogs in the wheel

According to her, anabolic steroids, the multiple analytical disciplines, and rapidly changing technical requirements from WADA have attracted her to the sciences of anti-doping. Sixty percent of her colleagues at SADoCoL are women.  “They are the cogs in the wheel, ensuring the laboratory's smooth operation, taking daily challenges in their stride, and excelling in what they do as analysts and administrative staff,” says Grobbelaar.

Grobbelaar says there are many options in the anti-doping field for women inside and outside of the laboratory. Some of the most influential people in the anti-doping community are women – in their roles as laboratory directors, leading researchers, directors of athlete passport management units for international sports federations, or national anti-doping agencies in various capacities.

With all the responsibilities, come challenges and pressure – especially in a year when the Olympic Games take place. 

Women should learn how to say ‘no’ 

“An Olympic year always has additional stress due to the large number of samples before the games. This year, the pressure is more, with not all accredited laboratories operational, as well as disrupted testing schedules due to COVID-19.  Enabling athletes to compete in fairness on the world stage is a responsibility and a privilege.”

“My faith is my anchor.  As far as possible, I try to leave my work behind when I leave the laboratory, and concentrate on enjoyable things such as gardening, my dog, reading, and walking with my dog. On challenging days, something sweet also helps,” explains Grobbelaar the pressure and how she copes with it. 

This Women’s Month, Grobbelaar says, women should learn how to say ‘no’ to create time for rest and play. Says Grobbelaar: “For many women, ‘doing your best’ or saying yes means working yourself to the point of a mental and physical breakdown. Having the courage to say no, loving oneself through rest and play, replenishing our spirits, and realising that we are unique and precious in God’s eyes, is a challenge that many women face.” 

“Rest and play can take different forms, such as having coffee with a friend or being creative.  The important thing is that your rest or play activity brings joy to your soul and energises you. Ask your friends to support and assist you,” she concludes.

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.
