The Council of the University of the Free State (UFS) unanimously approved the re-appointment of Prof Francis Petersen for a second five-year term as Rector and Vice-Chancellor of the UFS, as from 31 March 2022 to 1 April 2027. The decision was made during Council’s second scheduled meeting for the year, which took place virtually on 18 June 2021.

Council appreciation for exceptional leadership
“Prof Petersen’s first term was characterised by exceptional leadership and the Council has significant appreciation for the work that he has done and his accomplishments to date. Since his appointment on 1 April 2017 and under his leadership, the UFS has excelled in a number of key areas,” said Dr Willem Louw, Chairperson of the UFS Council.

Excellence, inclusivity, innovation, academic freedom, a particular focus and emphasis on critical enquiry, social responsiveness, integrity, and humaneness have been the value trademarks by which Prof Petersen operates. Early in his term – through a well-structured, thought-through, and consultative approach – he produced the strategic framework for the UFS for the period 2018 to 2022, the key performance areas of which have been implemented in most cases or are nearing completion.

“Prof Petersen has put forward a compelling set of drivers for his second term and indicated that he specifically intends to focus on and elevate the teaching and learning, research and internationalisation, and engaged scholarship portfolios of the university. On behalf of the Council, I wish him all the best with the second term and look forward with great expectation to what he and his executive team will achieve to further advance the UFS nationally and internationally,” said Dr Louw.

“I am humbled and honoured by the expression of confidence in me; it is a privilege to  continue leading one of the greatest universities in the country on its new journey. I will continue to do my utmost to build a strong institution that belongs to everyone, and want to thank our staff, students, and valued stakeholders for their continued support,” said Prof Petersen.

Achievements during first term
The UFS’ achievements during Prof Petersen’s first term include the implementation of an Integrated Transformation Plan (ITP) (towards social justice); the UFS Strategic Plan (towards expanding the scope of transformation); the Vice-Chancellor Strategic Projects (towards a high-performance institution); the institutional Risk Management Committee (towards risk management and risk philosophy); and the institutional Multi-Stakeholder Group (towards an inclusive institutional culture).

Further highlights include the development of differentiated research, internationalisation, and innovation strategies for the UFS; the development of Project Caring in the domain of the Unit for Institutional Change and Social Justice; facilitating an institutional governance project; development of a strategy and plans for a Digital Scholarship Centre; the development of proactive relationships with the Department of Higher Education, Science and Innovation and the National Student Financial Aid Scheme (NSFAS); and the establishment of a Reputation Management Forum to assist in improving the reputation and profile of the UFS.

Vision for the second term
Prof Petersen’s vision for his second term includes the continuation of the ITP, with a primary focus on the social justice imperative and ensuring the completion of all the deliverables; using the sustainable development goals (SDGs) as basis of the response as to how the UFS will affect society positively; using digitisation as key focus in determining how the academic project will be delivered, supported and how it is interfacing with the external environment; raising the external profile of the UFS through alumni, foundations, donors, and strategic communication as critical drivers; and to continue participating and further advancing national and global discourses.

Research eradicates bacteria from avocado facility

“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.
