The University of the Free State (UFS) is celebrating an outstanding achievement at the 12th Annual Green Campuses Conference (GCC) 2025, where its dynamic Green Campus Initiative (GCI) team from the Qwaqwa Campus clinched the coveted Best Exhibition Award. This marks an unprecedented fourth consecutive year that the UFS has secured this prestigious accolade, highlighting its unwavering commitment to sustainability and innovation within the higher education landscape.

Hosted by Nelson Mandela University in Gqeberha, Eastern Cape, the conference was presented by the Association of College and University Housing Officers - International (ACUHO-I) under the profoundly relevant theme, Ubuntu and Environment: African Indigenous Knowledge in Sustainability. Endorsed by the Department of Higher Education and Training, the GCC serves as a pivotal platform for institutions of higher learning across South Africa to exchange vital knowledge, share best practices, and explore groundbreaking innovations in environmental sustainability and climate change mitigation.

The UFS GCI team's exhibition captivated judges and attendees alike with its exceptional creativity, innovative spirit, and profound dedication to envisioning a greener future. "The creativity, innovation, and commitment to sustainability shone through every detail of the display," remarked residential head Itumeleng Lebusho, "a true reflection of what it means to envision a greener future".

The five students who represented the institution were Amukelani Ngobeni, Minenhle Mnguni, Sinenhlanhla Mathabela, Charmaine Nokubonga Nkosi, and Thandolwethu Nyathikazi.

A cornerstone of the student-driven conference, the GCC featured three main categories: project presentations, a runway showcase, and the highly anticipated exhibition. UFS students excelled across the board, demonstrating their ingenuity in tackling real-world campus challenges with sustainable solutions.

A particularly notable project was the student-designed mobile trolley. Addressing a common predicament faced by students transporting groceries from the main gate to their residences due to campus restrictions on taxis for security reasons, the team engineered an innovative solution. This solar-powered mobile trolley, equipped with batteries and a motor, began as a prototype in 2024 and has since evolved into a testament to student-led problem-solving. While the current iteration requires a Code 8 driver's licence to operate, its potential to revolutionise campus mobility is clear.

The conference's annual theme encourages participants to devise sustainable solutions to problems faced on campus, a challenge that the UFS GCI team has embraced with remarkable success.

The UFS' consistent triumph at the GCC is a testament to the dedication and sacrifice of its students, whose forward-thinking ideas continue to push the boundaries of what is possible in campus greening. "The students worked in a way that we never imagined," expressed Desiree Motsele, Residence Head within Housing and Residence Affairs. "The ideas that they come up with are truly inspiring."

By actively participating in this significant event, the UFS is not only strengthening its commitment to creating a green campus but also fostering a healthy learning and living environment. This continued dedication prioritises sustainability, advances energy efficiency, champions resource conservation, and promotes environmental stewardship, solidifying the UFS' position as a leader in sustainable practices within South African higher education.

The Director: Student Affairs, Zoleka Dotwana, said she would like to congratulate the students on yet another gold they won at the GCI 2025. “The effort, the hard work, the commitment you have shown, has once again raised our UFS flag high. I hope the experience and the graduate attributes you have learnt in preparing your project will go a long way in providing you with great opportunities when you leave our shores. It has been an awesome journey over the four years, one that we hold dear and that will remain in the history books of our campus. Thank you for flying our flag high - Only a Kovsie knows the feeling!' said an ecstatic Dotwana.

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.
