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.

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
