Vincent Mahapa 2024

The University of the Free State Qwaqwa Campus recently celebrated academic and holistic excellence at its annual Student Excellence Awards. The event honoured high-achieving students from various disciplines, as well as those who have made significant contributions to the campus community.

The air was electric with anticipation as the campus community gathered to honour its brightest stars. The annual Student Excellence Awards showcased the exceptional talents and achievements of students across academic and extracurricular realms. This event took place in the iconic Mandela Hall.

Vincent Mahapa, a dedicated 21-year-old from Bronkhorstspruit east of Pretoria, was recognised for his exceptional academic achievements by being awarded the prestigious Dux prize at the event.

Mahapa is on the verge of completing his Bachelor of Administration and Management degree in the Faculty of Economic and Management Sciences (EMS) and has consistently demonstrated academic excellence. In his second year, he achieved an impressive average of 82%, securing a remarkable seven distinctions in 2023. These outstanding results were further acknowledged through his induction into the prestigious Golden Key International Honour Society, Class of 2023.

Driven by a passion for public administration and management, Mahapa has a strong interest in black empowerment, organisational leadership, and community development. He aspires to leverage his skills and knowledge to drive positive change within these fields.

Overcoming challenges, achieving success

Mahapa's journey to academic excellence was not without its hurdles. He openly acknowledges the challenges he has faced in effectively managing time, balancing academic and personal life, staying motivated, and overcoming social anxiety. However, his determination to succeed shone through as he strategically tackled these obstacles.

Commenting on this laudable recognition, he said, “By creating a well-balanced schedule, setting realistic goals, and seeking support from peers and lecturers, I developed effective coping mechanisms.” He emphasised the importance of creating a study plan and adhering to it, along with techniques such as breaking down complex topics into manageable sections and employing the Pomodoro technique to optimise study sessions.

Words of wisdom for fellow students

As a Dux awardee, Mahapa offered valuable advice to his fellow students who aspire for academic excellence. He encourages them to:

  • seek help and support when needed;
  • remain consistent and persistent in their efforts;
  • set clear goals and work diligently towards achieving them;
  • develop strong organisational skills and manage time effectively; and
  • surround themselves with positive influences that will motivate and support their endeavours.
  • Finding balance for academic and personal well-being

Being an introverted individual, Mahapa acknowledges the importance of striking a healthy balance between academic commitments and personal life.  He achieves this by meticulously planning his schedule, allocating specific time slots for studying, relaxation, and personal activities. Setting realistic goals and further prioritising tasks allows him to manage his time effectively.

Additionally, he stresses the importance of creating a designated study space that is comfortable, organised, and minimises distractions, thus boosting productivity. Distinguishing the importance of self-care, Mahapa highlights activities that bring him joy and relaxation. He does not hesitate to seek support from loved ones and lecturers when needed, and regularly reviews and adjusts his approach to ensure a healthy balance that meets his individual needs.

The university congratulates him on this well-deserved achievement and commends him for his commitment to using his knowledge and skills to make a positive impact on society.

And a big congratulations to all the winners. Indeed, we are inspiring excellence!

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.
