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

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.

“The aim of my project was to identify and characterise the contamination problem in an avocado-processing facility and then to find a solution,” said Dr Amy Strydom, postdoctoral fellow in the Department of Microbial Biochemical and Food Biotechnology at the University of the Free State (UFS).

Her PhD, “Control of Listeria monocytogenes in an Avocado-processing Facility”, aimed to identify and characterise the contamination problem in a facility where avocados were processed into guacamole. Dr Strydom completed her MSc in food science in 2009 at Stellenbosch University and this was the catalyst for her starting her PhD in microbiology in 2012 at the UFS. The research was conducted over a period of four years and she graduated in 2016. The research project was funded by the National Research Foundation.

The opportunity to work closely with the food industry further motivated Dr Strydom to conduct her research. The research has made a significant contribution to a food producer (avocado facility) that will sell products that are not contaminated with any pathogens. The public will then buy food that is safe for human consumption.


What is Listeria monocytogenes?

Listeria monocytogenes is a food-borne pathogenic bacterium. When a food product is contaminated with L. monocytogenes, it will not be altered in ways that are obvious to the consumer, such as taste and smell. When ingested, however, it can cause a wide range of illnesses in people with impaired immune systems. “Risk groups include newborn babies, the elderly, and people suffering from diseases that weaken their immune systems,” Dr Strydom said. The processing adjustments based on her findings resulted in decreased numbers of Listeria in the facility.

The bacteria can also survive and grow at refrigeration temperatures, making them dangerous food pathogens, organisms which can cause illnesses [in humans]. Dr Strydom worked closely with the facility and developed an in-house monitoring system by means of which the facility could test their products and the processing environment. She also evaluated bacteriophages as a biological control agent in the processing facility. Bacteriophages are viruses that can only infect specific strains of bacteria. Despite bacteriophage products specifically intended for the use of controlling L. monocytogenes being commercially available in the food industry, Dr Strydom found that only 26% of the L. monocytogenes population in the facility was destroyed by the ListexP100TM product. “I concluded that the genetic diversity of the bacteria in the facility was too high and that the bacteriophages could not be used as a control measure. However, there is much we do not understand about bacteriophages, and with a few adjustments, we might be able to use them in the food industry.”

Microbiological and molecular characterisation of L. monocytogenes

The bacteria were isolated and purified using basic microbiological culturing. Characterisation was done based on specific genes present in the bacterial genome. “I amplified these genes with polymerase chain reaction (PCR), using various primers targeting these specific genes,” Dr Strydom said. Some amplification results were analysed with a subsequent restriction digestion where the genes were cut in specific areas with enzymes to create fragments. The lengths of these fragments can be used to differentiate between strains. “I also compared the whole genomes of some of the bacterial strains.” The bacteriophages were then isolated from waste water samples at the facility using the isolated bacterial strains. “However, I was not able to isolate a bacteriophage that could infect the bacteria in the facility.
