Students on the Bloemfontein Campus were treated to a lunch-hour music performance by the campus choir – an uplifting musical production led by the indomitable Sibongile Mngoma, conductor of the choir on the Bloemfontein Campus. The performance, which was in celebration of Human Rights Day, took place on 22 March 2022 in front of the Main Building.  “We realised that people were hungry to hear beautiful music and beautiful sounds, and we started these pop-up performances just to revive people’s spirit and to give them hope,” says Lucy Sehloho, Officer: Arts and Culture in the Department of Student Affairs. As such, the staff and students at the University of the Free State (UFS) can look forward to a series of pop-up performances by the UFS choirs, specifically on the Bloemfontein and South Campuses.

One institution, different sounds

According to Sehloho, “the choirs are all running on the same constitution and the same code of conduct”. However, they are slightly different in sound, and this is determined by the audience to whom the respective choirs cater, and the number of members involved in the choir. The Bloemfontein Campus choir is known to cover genres such as rap, trap, classical music, and South African choral music. However, the Qwaqwa Campus choir focuses on choral music and various African sounds, while the South Campus choir manoeuvres through most of the abovementioned genres.

Preparing for life as an artist after university 

It is important to note that the choirs are not just a safe space that encourages expression for young artists. Indeed, for many students it is also the beginning of a career. As such, they are taught lessons about financial literacy and the ability to brand themselves as artists. “One of the things I am teaching the students is how to price and cost themselves,” Sehloho highlighted. In fact, Sehloho argues that a major challenge among young performers when they leave university, is that – because they have never charged a fee for their service – they have no idea how to price and sustain themselves from the money they acquire. Consequently, industry experts are invited to provide insight into the realities of the world for artists once they start working. These industry experts include Dr Jerry Mofokeng wa Makhetha.

Future endeavours for the respective choirs

In addition to these lessons, the choirs have various projects that they are working on. The Bloemfontein Campus choir is currently planning performances for national holidays such as Freedom Day and Youth Day. The choir is also gearing up for a performance of Handel’s Messiah in celebration of Easter. The South Campus is specifically working towards the Network Festival in collaboration with Oranje Girls’ School. Furthermore, the Bloemfontein Campus choir will compete in the Sing for Gold competition in Barcelona this coming October. Once an institutional choir has been finalised, the Arts and Culture team will represent the UFS and the nation at the World Choir Games in 2023.

The main challenge experienced by the choirs

Although the choirs are succeeding in entertaining and uplifting the UFS community, there are still some challenges that hinder their growth to some extent. Racial diversity is one of these barriers. ‘’When someone looks at the choir, they don’t get to see the full picture of who we as the University of the Free State are in terms of diversity,’’ she explains. Therefore, Sehloho notes that the respective choirs are open to students from all walks of life in order to ensure racial and cultural diversity. As such, students who are interested in joining can contact Lucy Sehloho at  SehlohoLP@ufs.ac.za

“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.
