Reading Culture
The University of the Free State Faculty of Humanities and the Library Information Services proudly established a brand-new school library at Kagisano Combined School on 14 May 2024.

In a bid to cultivate a culture of reading within the community and bolster the University of the Free State's (UFS) Vision 130, the Faculty of The Humanities has embarked on a transformative journey of collaboration with the Library Information Services (LIS). This partnership symbolises a commitment to not only academic excellence, but also social responsibility, aiming to make a tangible difference in the lives of those within our community.

On 14 May, the Dean’s office – in synergy with LIS and the Department of Plant Sciences – undertook a meaningful venture at Kagisano Combined School in Ikgomotseng to establish a school library, making it an engaging and welcoming space for learners.

Led by Dr Dimitri Veldkornet and supported by four dedicated PhD candidates, the Department of Plant Sciences has made a remarkable impact by enhancing the library's surroundings with indigenous flowers. Beyond mere beautification, this initiative also served as an educational opportunity, as five learners from the school were trained to care for these plants, fostering a sense of ownership and environmental stewardship.

Colleagues from LIS meticulously and simultaneously organised the library space, ensuring that reading materials were properly catalogued and shelved for easy access. In addition, LIS generously donated furniture, including shelves, tables, and chairs, to create an inviting environment conducive to learning and exploration.

The collaborative effort extended beyond academic circles, as the community of Ikgomotseng and Letsatsi Trust demonstrated remarkable hospitality by combining resources to provide refreshments for UFS colleagues and community members involved in the initiative. This gesture exemplifies the power of collective action and highlights the interconnectedness between the university and its surrounding communities.

By revitalising the school library and fostering a culture of reading, this partnership exemplifies the core values of social responsibility and community engagement espoused by the UFS. Moreover, it underscores the university's commitment to Vision 130, which envisions a future where education transcends the confines of academia to positively impact society at large.

As we continue to forge ahead, let us remember that true progress is measured not only by academic achievements, but also by the meaningful contributions we make to the communities we serve. Together, through collaboration and compassion, we can create a brighter, more inclusive future for all.

“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.
