UFS talks Open Access 2020

The Library and Information Services of the University of the Free State (UFS) and the Central University of Technology,Free State (CUT) jointly hosted an Open Science Colloquium on 19 November 2019. The colloquium was in response to the national and international developments in what is referred to as ‘the Open Access 2020 (OA2020) movement’. This movement calls on all parties involved in scholarly communication to take action to make their scholarly outputs open and freely available to all citizens of the world. It is a move against the current subscription-based model of publication, which has proved to be costly and unsustainable, and which limits access to knowledge to a few, making it unacceptable.

Welcoming more than 200 delegates to the UFS, Ms Betsy Eister, Director: Library and Information Services, referred to OA2020 as a disruption in the publishing arena.

Endorsing the Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities

The colloquium comes as an endorsement of the Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities that the two universities signed eight years ago. As signatories, the UFS and CUT have committed to the wide and free dissemination of its scholarship by means of open access platforms. This declaration was confirmed by the Rector and Vice-Chancellor, Prof Francis Petersen.

“When the UFS signed the Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities in 2011, this university committed itself to the wide and free dissemination of its scholarship by means of open access platforms. At that point, we have already made that commitment to open access platforms.”

Open access vs subscription

Prof Petersen said challenging the current status quo will bring equity into the system, which will “ensure that our younger cohort of researchers and scholars have the ability to freely conduct research, to freely access material, so that we can produce high-quality researchers and scholars for our system”.

Also present was Prof Ahmed Bawa, Chief Executive Officer of Universities South Africa, who echoed Prof Petersen’s message by making a case for management, researchers, libraries and research funders to work together to make OA2020 a reality. “These discussions are very important because it provides us with an opportunity to build international consensus on these things, which is critical in moving forward.”

Prof Ahmed Bawa, Chief Executive Officer of Universities South Africa addressed delegates on the importance of open access.

Mr Glenn Truran, Director of the South African Library and Information Consortium (SANLiC), and Ms Eister addressed the national and local roadmaps, respectively. SANLiC, a consortium that negotiates deals for electronic resource subscriptions on behalf of all 26 public universities and eight research councils, has already started transformative agreement negotiations with international publishing company Taylor and Francis.

The colloquium ended with a declaration signed by members present, hoping that it would be signed by all concerned as a commitment to taking action towards open access. The two universities will ultimately sign the OA2020 Expression of Interest.

• The UFS and CUT Libraries are thankful to Mr Gareth O’Neill and UFS colleagues (Mr Charlie Molepo and Mrs Cornelle Scheltema-Van Wyk), who shared information with the attendees on transformation agreements (also referred to as Plan S) and AmeliCA, respectively. Plan S deals with transformation agreements to be signed with publishers, which are about negotiations with publishers to change from subscription-based to open-access journal publishing models. Mr Molepo and Mrs Scheltema-Van Wyk showcased the open access model that the UFS Library has already implemented, which is what AmeliCA is all about. This involves the publication of nine accredited UFS journals on the Open Journals System platform, which enhance its discoverability and accessibility. It was also a pleasure to listen to Prof Abdon Atangana from the UFS Institute for Groundwater Studies – a classic example of an activist and beneficiary of open access publishing – who was recently named as one of the top-10 cited researchers in the Web of Science, thanks to open access publication.

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.
