Department of Chemistry strengthens international ties through International Chemical Symposium

The Department of Chemistry at the University of the Free State (UFS) held a successful online International Symposium on Organic Chemistry on 15 June 2021. The symposium brought together scientists from several South African and foreign universities and created a virtual platform for a long-awaited discussion stalled by the COVID-19 pandemic. About 20 participants from universities in South Africa, Belgium, and Germany presented their lectures during the symposium. In addition, this symposium was directed at the postgraduate students in the Department of Chemistry at the UFS, allowing them to present their results to an international audience and to foster their engagement in scientific research.

For more than a year, the COVID-19 pandemic has prevented the common personal communication avenues for the researchers: face-to-face (F2F) conferences, symposia, and workshops. To bridge this gap, Prof Vladimir Azov and Dr Charlene Marais from the Department of Chemistry organised the online meeting for the researchers from the UFS and several other local and foreign universities, all working in the field of organic chemistry.

Collaborative project between the UFS and VUB towards the development of gel-based drug release systems

The symposium also served as a long-awaited inception meeting for the collaborative project between the Organic Chemistry group at the UFS and the Organic Chemistry (ORGC) group at the Vrije Universiteit Brussel (VUB). This project is jointly funded by the National Research Foundation (NRF) and FWO (Research Foundation – Flanders); it is aimed at the development of new peptide-based materials with properties controllable by precisely tuned interactions of unnatural amino acids included in the peptide sequence. Such peptides can, for example, be used as smart materials for precisely controllable drug release. The South African team members, directed by Prof Vladimir Azov, will specialise in the development of the new amino acid building blocks, whereas the VUB team, headed by Prof Ulrich Hennecke, will focus on peptide preparation and studies on their properties.

This kick-off meeting was initially planned as a F2F event in June 2020 but was delayed due to the COVID-19 travelling restrictions and finally migrated to a virtual space. This provided an opportunity to present the project proposals and to discuss the initial results in a much broader circle than would have been possible within the common F2F meeting framework.

UFS leads the way with GMO testing

2003-08-25

A formal agreement linking Africa’s first testing facility for genetically modified organisms (GMO) to an international organization was signed at the University of the Free State.

According to the manager of the GMO testing facility, Dr Chris Viljoen of the Department of Plant Sciences, the facility is now part of GeneScan, a world leader in food diagnostic testing, which has its headquarters in Germany with subsidiaries in the Unites States, Brazil and Hong Kong.

The facility at the UFS has been selected by the second largest international food company to do all its South African GMO testing for export products.

The GMO testing facility is the brainchild of Dr Viljoen, who is a specialist in the field of marker biotechnology and its applications in crop science.

He says the need for such a testing facility arose due to the international regulations on GMOs in food, especially Europe and Asia that requires South African exporters to certify whether their products contain any GMO.

“The regulations in Europe and Asia reflect a consumer need for choice in what they eat due to concerns over the safety of GMOs, as well as environmental and ethical issues. GMO testing and labelling allow consumers the right of choice to eat genetically modified foods or not. According to EU regulations, any product with a GMO content of 1% or higher is labelled as containing GMO.”

According to Dr Viljoen only four products in South Africa are currently GMO. They are white and yellow maize that have been made insect resistant, soya bean that is herbicide tolerant and insect resistant cotton. He says that the awareness of GMOs among South Africans is still very limited, especially in poorer communities, but it is likely to increase with the efforts being made in consumer education by government, seed companies and NGOs.

The testing facility has been established to accommodate the local as well as international market. The GMO testing at the UFS facility is performed using real time PCR, the most advanced means of GMO detection currently available, and using GeneScan developed technology that is recognized worldwide.
