Prof Fanie Snyman, retired Dean of the Faculty of Theology and Religion, is the first South African to publish a volume in the respected Tyndale Old Testament Commentaries series, which deals with the Bible books of Nahum, Habakkuk, and Zephaniah.

Against the backdrop of the Faculty of Theology and Religion’s 40th anniversary, Prof Fanie Snyman, retired Dean and research associate, has recently published a commentary in the Tyndale Old Testament Commentaries series based in Cambridge, England, on the prophetic books Nahum, Habakkuk, and Zephaniah of the Old Testament. What makes his book special is that Prof Snyman is the first and for the foreseeable future the only South African Old Testament scholar to be commissioned to publish in this distinguished commentary series. This commentary series is widely read and consulted in the English-speaking scholarly communities of Africa, Australia, Great Britain, New Zealand, the USA, and many European countries.

In a virtual ‘sit-down’ with Prof Fanie, he explained how a research volume of this type is usually compiled: It starts with a verse-by-verse analysis of the Bible books, looking at the literary aspects of how the passage was written as well as considering its historical, social, and cultural background. This is done to obtain a better overall understanding of the text. Secondly, a volume of commentary is not merely regurgitating knowledge that has already been generated. Prof Fanie says that “it must deliver new, fresh perspectives on the current state of research on these books. What can I contribute to the understanding of these writings?” To accomplish this, he had to pore over stacks of research on these prophetic works to be as current as possible with modern research.

First contributor from Africa

Dr David Firth, the series editor, says: “Over the nearly sixty-year history of the Tyndale Old Testament Commentaries, we have not previously had any contributors from Africa. That has now been put right with the release of Prof SD Snyman’s new volume on Nahum, Habakkuk, and Zephaniah. Prof Snyman has brought together his expertise on the prophetic literature of the Old Testament and theological awareness to present a fresh work on these often-neglected books. Through his careful attention to how these books functioned in their ancient setting and mastery of the secondary literature, he is also able to point to the enduring importance of each of these books for contemporary readers. As such, he has admirably fulfilled the brief for the series and produced a volume that will serve a new generation who come to these books.”

Prof Fanie affirms that the burning issues raised in each of these books regarding situations in ancient Israel often mimic comparable issues in our modern society. For example, he underscores how Nahum brings the misuse of political power to the fore, a current and topical point of contention. Prof Snyman says: “My aim was to create a vertical theological perspective of that historical situation against the backdrop of contemporary issues. I believe that these texts have a relevance for us and upon us today.”

Other international works

This book is the third one published internationally by Prof Snyman. In 2012, he published a book on the prophetic literature of the Old Testament together with a Dutch colleague in the USA. In 2015, he published a commentary on the book of Malachi in Europe. This book was awarded the UFS Book Prize for Distinguished Scholarship in 2017.

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.
