As a transforming university, the University of the Free State (UFS) strives to cultivate an environment that is inclusive and socially just. In order to achieve this goal, the UFS adopted an Integrated Transformation Plan (ITP) as a framework to guide the transformation process. One area of transformation which we identified was: Names, Symbols and Spaces. A cross-functional task team responsible for this area is currently embarking on a process of reviewing how space and symbolic representation facilitates or hinders social inclusion in a diverse community. 

Monuments such as statues play an important symbolic role in people’s lives, with each monument being built for specific reasons and intended to serve particular purposes or interests. Monuments are erected as part of a visual culture that continually reminds us of something or someone important; yet, the symbolic value of monuments may change. Such values may acquire or lose importance, depending on fluctuating socio-political dispensations and dispositions. 

The student community, through the Student Representative Council (SRC), has made several representations in the past, and again on 8 March 2018 during a quarterly student engagement session with the Rector and Vice-Chancellor, Prof Francis Petersen, to review the position of the President Steyn statue in front of the Main Building on the Bloemfontein Campus in the current, liminal transformation space – particularly, its symbolic representation within a university community that is striving to create inclusive public spaces and advance nation-building and social cohesion.
 
Prof Petersen acknowledged the urgency of this matter and subsequently appointed a task team to focus on this request. The task team functions as a sub-committee of the ITP work stream on Names, Symbols, and Statues and consists of subject experts, members of the SRC, heritage professionals, and individuals who understand the complex issue of institutional culture.

 The task team recognises the fact that the review is a sensitive process, and has made significant progress while aligning itself to relevant legislation. As part of the review process, the task team has decided to make a submission to the Free State Provincial Heritage Resources Authority in order to obtain a permit to cover the MT Steyn statue while the review process is conducted, and an outcome has been reached. The task team is of the opinion that wrapping the statue symbolises the seriousness and urgency of the review process. 

In preparing the application for a permit to the Provincial Heritage Resource Authority, the task team would like to engage with all relevant stakeholders by requesting them to make submissions, indicating if they agree or disagree with the covering of the statue.
 
Stakeholders can make submissions in the following ways:

Written submissions can be sent to news@ufs.ac.za until 16:30 on Wednesday 11 April 2018.
 
The written submissions will be incorporated in the application for a permit and, after the decision has been made by the permit committee, there will be a 14-day-period during which the public may appeal the decision. 

As part of the Framework of Engagement on the President Steyn statue, the task team is also in the process of appointing a consultant to conduct a heritage impact assessment as required by the heritage authorities. Clear time frames on key deliverables will be shared with the UFS community at the start of the second term. 
The task team is committed to engage on this process with the appropriate urgency, cognisant of what is legislatively required in terms of the heritage authorities.

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.
