Famelab
Abdullahi Jamiu, who is working on his master's degree in Microbiology, was adjudicated as the FameLab winner at the Central Regional Heat and will represent the region at the national semi-finals.

Abdullahi Jamiu, who is working on his master's degree in Microbiology in the Department of Microbiology and Biochemistry at the University of the Free State (UFS), was recently announced as the FameLab winner at the Central Regional Heat and will represent the region at the national semi-finals.

Abdullahi, who plans on pursuing a doctoral degree after his master’s, says he wants to establish himself as an academic in microbiology.

Making science simple
He says he decided to participate in the FameLab competition because he is very passionate about communicating science. “Science communication affords me the opportunity to not only take my research outside of the lab space, but also to communicate it to the lay audience. Moreover, science is often perceived by the general public as difficult and unfathomable. As such, science communication programmes promote the simplification and better understanding of scientific knowledge in the community,” he says.

FameLab is coordinated by the South African Agency for Science and Technology Advancement, the British Council, and Jive Media Africa.

According to Abdullahi, the experience was mind-blowing. “It gave me the opportunity to compress my 200-page master's thesis into a three-minute talk in a way I had never thought was possible. Having to present virtually and adjust to the ‘new normal’ was quite challenging,” he adds.

“The overall experience was enlightening and engaging, and at the same time entertaining,” says Abdullahi.

Impressing the judges with his charisma, engagement with the audience, and use of props, Abdullahi’s presentation focused on how the exploration and exploitation of a ‘combination therapy’ approach to drug discovery could help to effectively combat fungal infections, which are the common comorbidities in immune-compromised individuals, including those living with HIV, cancer, and COVID-19.

Revealing an enigma
His fascination with microbiology started at a young age. “How very tiny, microscopic creatures, invisible to the unaided eye, are able to infect and sometimes kill both healthy and immune-compromised individuals, was an enigma to me as a little boy. My desire to unravel this mystery triggered my interest in microbiology, and the more I learn, the more enthusiastic I become to broaden my horizon in this challenging yet exciting field of study,” he says.

Abdullahi would like to one day make a difference by conducting relevant research aimed at contributing to finding lasting solutions to the lingering menace posed by pathogenic microbes. “Moreover, I am very passionate about facilitating the transfer of scientific knowledge to the next generation,” Abdullahi concludes.

Several industries in South Africa are currently producing hundreds of thousands of tons of carbon dioxide a year, which are released directly into the air. A typical family sedan doing around 10 000 km per year, is annually releasing more than one ton of carbon dioxide into the atmosphere.

The Inorganic Chemistry Research Group in the Department of Chemistry at the University of the Free State (UFS), in collaboration with the University of Zurich in Switzerland, has focused in recent years on using carbon dioxide – which is regarded as a harmful and global warming gas – in a meaningful way. 

According to Prof André Roodt, Head of Inorganic Chemistry at the UFS, the Department of Chemistry has for the past five decades been researching natural products that could be extracted from plants. These products are manufactured by plants through photosynthesis, in other words the utilisation of sunlight and carbon dioxide, nitrogen, and other nutrients from the soil.

Caffeine and chlorophyll 
“The Inorganic group is systematically researching the utilisation of carbon dioxide. Carbon dioxide is absorbed by plants through chlorophyll and used to make interesting and valuable compounds and sugars, which in turn could be used for the production of important new medicines,” says Prof Roodt.

Caffeine, a major energy enhancer, is also manufactured through photosynthesis in plants. It is commonly found in tea and coffee, but also (artificially added) in energy drinks. Because caffeine is a stimulant of the central nervous system and reduces fatigue and drowsiness, some people prefer decaffeinated coffee when enjoying this hot drink late at night. 

Removing caffeine from coffee could be expensive and time-consuming, but also environmentally unfriendly, because it involves the use of harmful and flammable liquids. Some of the Inorganic Group’s research focus areas include the use of carbon dioxide for the extraction of compounds, such as caffeine from plants. 

“Therefore, the research could lead to the availability of more decaffeinated coffee products. Although decaffeinated coffee is currently aromatic, we want to investigate further to ensure better quality flavours,” says Prof Roodt.

Another research aspect the team is focusing on is the use of carbon dioxide to extract chlorophyll from plants which have medicinal properties themselves. Chemical suppliers sell chlorophyll at R3 000 a gram. “In the process of investigating chlorophyll, our group discovered simpler techniques to comfortably extract larger quantities from green vegetables and other plants,” says Prof Roodt.

Medicines
In addition, the Inorganic Research Group is also looking to use carbon dioxide as a building block for more valuable compounds. Some of these compounds will be used in the Inorganic Group’s research focus on radiopharmaceutical products for the identification and possibly even the treatment of diseases such as certain cancers, tuberculosis, and malaria.
