Transformation at the university must be reflected in all dimensions of the institution, such as leadership, governance, and management, student backgrounds such as practical access and academic excellence, equity in staffing, institutional cultures, and inclusive teaching and learning. I acknowledge that this is not an easy task for universities, and that is why I would urge the student population to exercise patience on some of the matters they bring to the institution. However, they should also not be used by the university as a crutch in undertaking its obligation to transform and promote integration, non-discrimination, and inclusivity across all levels –  not only within the university, but also within the local space where the university finds itself, as we know the history of the institution. We have come a long way and there is still more to do, things to change, but we have to give credit where it is due. I still appeal to the institution to do more, because for some students it is the place that will give them the capability to fight poverty, to prosper, to influence change in society, and to change their lives as well as the lives of their families.

The redress of historical inequalities between historically white and historically black universities – it is a challenge for all universities, and we have come a long way to resolve this. With a new culture of students comes a new challenge, such as the funding challenges that poor and middle-income students are constantly facing. These are some of the recurring issues faced by students continually, requiring a solution that does not impoverish the poor even more. Universities must become spaces for transformation, rather than merely being transformed spaces. It is the transformative development through which students come to understand social justice properly, which certifies that students will go on to promote social justice in the wider society. While universities have long been sites of personal growth and transformation for their students, the impact of the transformative power of these places and the important transformational goal of generating graduates who are engaged citizens working for social justice must not be overlooked, particularly in the literature of transformation at the university.

Similarly, what is questioned by the students themselves is the relevance of what is taught at universities, how students are prepared through the knowledge and skills 'transmitted' to them for life in a South African context, and in what sense graduates are prepared to contribute to the advancement of society after the completion of their degrees. It cannot be that in this era we produce graduates who are job seekers, especially considering the status our country is in. This should be carefully considered in the development of the university’s curriculum and in its strategies.

It is only through an epistemic revolution in institutional culture that universities can become spaces that foster the development of civic-minded graduates. We cannot be relegated to just being students when it comes to the issues raised above if transformation is to take place effectively. Students must also understand that we cannot continue to do things as if it were 1976; we need to find other alternative mechanisms to voice our concerns and make an impact. At times change is not easy and it is not comfortable, but we are ready!

“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.
