Bachelor of Education third-year student, Moeketsi ‘Escalator’ Ngesemane.

By day he is a third-year Bachelor of Education student on the Qwaqwa Campus, but this young man is a Sesotho music maestro with a deep-rooted passion for traditional music and a diligent devotion to unearthing new talent and connecting more people to the cultural artistry that Sesotho music has to offer.

Moeketsi Ngesemane, better known as ‘Escalator’ in the world of music, is only 22 years old, but he has already released one solo album and featured in two more, leads a group of more than 80 traditional singers and dancers, and is responsible for a string of groups around Qwaqwa. He has made strides far beyond his age, and Ngesemane says he is only getting started. He was also instrumental in coordinating the Qwaqwa traditional groups that performed during this year’s Multilingual Mokete festival, where he also featured.

Born and bred in Qwaqwa, Ngesemane pins his love for traditional music as something that was cultivated in his childhood while singing traditional songs with his mother and brother. “My mother is a traditional healer, so Sesotho music was a big part of my upbringing. As I grew older, my brother and I would perform in town and people would give us money. I have not looked back since.”

He cemented himself as an artist and artist manager in his first year in 2009. The name ‘Escalator’ came about in an uncanny way, as he fondly recalls. “I had a friend who was afraid of escalators when he first saw it – but I wasn’t, so he named me ‘Escalator’. I hated the name until I personalised the meaning behind it. It is able to take people from one point to another and from one level to another, which is something I am passionate about doing through traditional music, so the name was fitting.”

He captivated the minds and hearts of both young and old people who want to be under his leadership, and he grooms young people as young as ten, who will also thrive and take traditional praise singing and dancing to greater heights. This, he says, helps him alleviate some responsibilities so that he can focus on his schoolwork.

Celebrating the Sesotho culture through music

Word about his music skill often spreads quickly. “Even when I am on teaching practicals at different schools, once learners find out what I do, they ask to join my group and I can’t say no. Their ages range from 7 to 21, and I know that my group will have more than 100 members before the year ends,” he said.

He often puts together music shows with his group around Qwaqwa. This, he says, he does to promote Sesotho music and art.

Ngesemane has been selected to represent the Basotho Kingdom at the Indoni Mr and Miss Cultural South Africa – an indigenous event focused on promoting South Africa’s diverse cultural heritage, taking place at the Durban ICC on 17 December. He describes this as a dream come true.

“It’s a great honour to be representing the Basotho culture. I have discovered that young people, especially, have neglected their cultural roots and often look down on traditional music and regalia. I’ve made it my personal aim to promote and uphold the Sesotho culture through praise singing and dancing.”

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.
