Sifiso Banda
Sifiso Banda balances library duties and academic goals, showcasing innovation and resilience at the UFS Qwaqwa Campus.

In the heart of the University of the Free State Qwaqwa Campus, Sifiso Banda's story is one of ambition, and the seamless fusion of seemingly disparate worlds. Balancing his role as Senior Assistant Officer: Circulations and TK Mopeli Makerspace in the library with the rigorous demands of a BSc Honours Degree in Computer Science, Banda has not only excelled but also inspired.

 

Overcoming challenges fuelled by dreams

"Computer Science is my primary passion," Banda explains, his voice resonating with determination. "Being in academia allows me to interact with ever-evolving technologies. I love problem-solving and creating new ideas to help my community. “However, the path was far from easy. Juggling a demanding job with intense academic pressure led to sleepless nights and near-burnout. "It required immense professionalism in time planning and management," he confesses. "I almost gave up, but the unwavering support of my colleagues and supervisors kept me going."

Banda's journey is a testament to the power of perseverance, fuelled by a deep sense of responsibility and gratitude. "I had to remind myself daily who I was doing this for," he says, his voice filled with emotion. "My late mother used her last savings to register me for university, giving me an opportunity she never had. That memory pushed me through the pain."

 

From theory to practice: Innovating library technology

His unique position within the library has provided an unexpected synergy with his Computer Science studies. "I saw a gap to bridge theory with practical application," Banda explains. "I want to use my tech skills to innovate and make education engaging, developing systems and apps that simplify student life."

He discovered that library science extends far beyond traditional book management. "It's not just borrowing and cataloguing," he says. "There are diverse career paths for a computer scientist, such as systems librarian."

Banda's practical application of his computer science knowledge is evident in his daily work. He plays a key role in managing and configuring the library's technology, including RFID self-check machines and automated chutes. Notably, a YouTube demonstration he created showcases his ability to bridge the digital divide for library users.

The most daunting challenge was his mini-dissertation. "It demanded immense time, often encroaching on my work hours," he recalls. "Balancing coding, documentation, and assisting patrons was incredibly difficult."

 

Evolving technology and support

His fascination with computer science stems from its dynamic nature. "Technology evolves daily," he says. "I'm particularly drawn to artificial intelligence and machine learning, as I envision a future where everything is digitised. My childhood dream was to build robots that could assist in households."

Banda credits several mentors for their profound impact on his academic journey. Prof Richard Ocaya, Prof Lehlohonolo Koao, Dr Andronicus Akinyelu, and Adebola Musa all provided crucial guidance and support. He also acknowledges the invaluable emotional support from Nonhlanhla Moleleki, a counsellor, and Khethiwe Bhiyo, his academic adviser. "The community at large played a vital role," he emphasises.

His advice to students working while studying is simple yet powerful: "Everything is possible with consistency, persistence, determination, and dedication. Keep focused, no matter how long it takes."

His research project, an online dining hall purchasing system, exemplifies his commitment to community-driven innovation. "It has reduced wait times and queues across our campuses," he says proudly.

Looking ahead, Banda plans to pursue a master's degree, aiming to combine his library experience with his technical expertise. "I envision libraries becoming increasingly digitised, and I want to be part of that evolution," he states.

The skills he gained – time management, multitasking, collaboration, and the courage to seek help – will be invaluable in his future endeavours. "Most importantly, believe in yourself," he concluded.

“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.
