Prof Carlien Pohl-Albertyn, a successful scientist, is living her dream job, as she gets to pursue her passion for microbiology; a career she wanted to pursue ever since Grade 10.

Prof Carlien Pohl-Albertyn, a professor of Microbiology in the Department of Microbiology and Biochemistry, is the holder of the SARChI Chair in Pathogenic Yeasts at the University of the Free State (UFS). She is leading the Pathogenic Yeast Research Group, studying pathogenic yeast infections and necessary treatment options and bringing hope to many immunosuppressed patients battling HIV/Aids, cancer, diabetics, and other diseases. She also recently co-authored an article on the incidence of fungal infections in COVID-19 patients. 

“This is my dream job, as I get to pursue my passion for microbiology,” says Prof Pohl-Albertyn, who already knew as early as Grade 10 that she wanted to become a microbiologist. “I have always been fascinated by the natural world and have known since childhood that I would become a scientist,” she says. 

An interview with Prof Pohl-Albertyn reveals more about the persons who inspired her, her view on the development of women, and how she approaches her work. 

Is there a woman who inspires you and who you would like to celebrate this Women’s Month, and why?

“The first woman who instilled a love for the biological sciences in me was Miss Steyn, my high school Biology teacher. She had a passion for teaching that inspired me to become a microbiologist.”

Prof Pohl-Albertyn, however, states that there were many other women who constantly inspired her to be a better person. 

“My mother inspires me to take responsibility for my choices; my mother-in-law inspires me to be kinder to others; and my best friends’ mothers inspire me to persevere, even when things are difficult.”

“I am also inspired by my female friends, Ezelle van den Heever, who has shown me that there is always a plan to be made to solve a problem; Trudi O’Neill, who manages to balance high-level research, teaching, and administration with her home life; Alicia Sherriff, from whom I am learning to be more emotionally intelligent; and Janine Allen, who has expanded my horizons and regularly shows me how to look at the world in a completely different way.”

What is your response to current challenges faced by women and available platforms for women development?

“Coming from a fairly male-dominated cultural background, I realise that I have been very privileged to not experience challenges just because I am a woman. I have been able to study and work in a field that values women and men equally and have chosen a very capable and extremely supportive husband, who sees me as an equal.”

She, however, realises that this is not the case for many women, and understands that there are women who were not able to follow their dreams and make their own life choices.

Prof Pohl-Albertyn believes that any opportunity for women to overcome challenges should be encouraged, as a society will ultimately be better if everyone is able to fulfil their greatest potential.

What advice would you give to the 15-year-old you?

This successful scientist, spouse, mother of two sons, daughter, friend, and mentor to many, says that she will advise her 15-year-old self to do everything the way that she has been doing it. “I do not regret anything and would not change my life in any way,” she says. 

What would you say makes you a woman of quality, impact, and care?

“I am a person of quality because of my integrity, work ethic, and commitment to my responsibilities – something that is easy if you enjoy what you do every day.”

“I am a person of impact because of the influence I have on my colleagues, who I always treat with respect, and my students, who I teach to the best of my abilities, and which I hope will serve them well in their careers.”

“I am a person of care because I value the contributions of my colleagues and students to my own growth and development,” remarks Prof Pohl-Albertyn.

Research on cactus pear grabs attention of food, cosmetic and medical industry

The dedicated research and development programme at the UFS on spineless cactus pear (Opuntia ficus-indica) – also known as prickly pear – has grown steadily in both vision and dimension during the past 15 years. Formal cactus pear research at the UFS started with the formation of the Prickly Pear Working Group (PPWG) in June 2002. It has since gone from strength to strength with several MSc dissertations and a PhD thesis as well as popular and scientific publications flowing from this initiative.

According to Prof Wijnand Swart from the Department of Plant Sciences, the UFS is today recognised as a leading institution in the world conducting multi-disciplinary research on spineless cactus pear.

Cactus pear for animal feed

Increasing demands on already scarce water resources in South Africa require alternative sources of animal feed – specifically crops that are more efficient users of water. One alternative with the potential for widespread production is spineless cactus pear. It is 1.14 x more efficient in its use of water than Old man saltbush, 2.8 x more efficient than wheat, 3.75 x more efficient than lucerne and 7.5 x more efficient than rangeland vegetation.

“Studies on the use of sun-dried cactus pear cladodes suggest that it has the potential to provide some 25% of the basic feed resources required by South Africa’s commercial ruminant feed manufacturing sector,” says Prof HO de Waal of the Department of Animal, Wildlife and Grassland Sciences at the UFS.

Until recently, research has focused extensively on the use of cactus pear as drought fodder. However, this is now beginning to shift, with growing interest in the intensive production of spineless cactus pear for other types of animal feed. One example is the spineless cactus pear fruit, produced seasonal, yielding large quantities of fruit in a relatively short period of a few months in summer. Unless kept in cold storage, the fruit cannot be stored for a long period. Therefore, a procedure was developed to combine large volumes of mashed cactus pear fruit with dry hay and straw and preserve it for longer periods as high moisture livestock feed, kuilmoes – a high water content livestock feed similar to silage.

Cactus pear for human consumption

“In addition to its use as a livestock feed, cactus pear is increasingly being cultivated for human consumption. Although the plant can be consumed fresh as a juice or vegetable, significant value can be added through processing. This potential is considerable: the plant can be pickled; preserved as a jam or marmalade; or dried and milled to produce baking flour. It can also serve as a replacement of egg and fat in mayonnaise,” said Dr Maryna de Wit from the Department of Microbial, Biochemical and Food Biotechnology.

The extraction of mucilage from fresh cladodes can form a gelling, emulsifier, and fat-replacing agent commonly found in food products such as mayonnaise and candy. During an information session to the media Dr De Wit and her team conducted a food demonstration to showcase the use of the cladodes in a juice, chicken stir-fry, biscuits and a salad.

The extrusion of cactus pear seed oil provides a further lucrative niche product to the array of uses. These include high-value organic oil for the cosmetic sector, such as soap, hair gel and sun screens.

The cladodes and the fruit also have medicinal uses. It has anti-viral, anti-inflammatory, pain killing and anti-diabetic agents. It is also high in fibre and can lower cholesterol. The fruit also prevents proliferation of cells and suppresses tumour growth and can even help to reduce a hangover.

In South Africa the outdated perception of cactus pears as thorny, alien invaders, is rapidly disappearing. Instead, farmers now recognise that cactus pear can play a vital role as a high yielding, water-efficient, multi-use crop, said Prof de Waal and the members of the Cactus Pear Team.
