They believe publishing in high-impact factor journals reflects the quality of research delivered by the department.

Researchers in the Department of Microbial, Biochemical and Food Biotechnology at the University of the Free State (UFS) published their work in four impact factor eleven journals in 2019/2020, and a fifth was accepted for publication in a journal with impact factor twelve in 2020. 

Two articles were published in Nature Communications, one in Drug Resistance Updates and one in Natural Product Reports. A fifth article is already available as an accepted article at Angewandte Chemie. Researchers in the department work on very diverse topics, as reflected in the titles of these articles: ‘A chemo-enzymatic oxidation cascade to activate C–H bonds with in situ generated H2O2’; ‘Native roles of Baeyer–Villiger monooxygenases in the microbial metabolism of natural compounds’; ‘The genome of a subterrestrial nematode reveals adaptations to heat’; ‘Molecular basis of bacterial disinfectant resistance’; and ‘CYP505E3 – a novel self‐sufficient ω‐7 in‐chain hydroxylase’.

Publishing in journals with a high impact factor is quite an achievement. Publishing in a journal with an impact factor of 3 is considered good and in most fields of study, publishing in journals with an impact factor of 10 or more is regarded as excellent. Impact factors are used to measure the importance of a journal by counting the number of times articles were cited in a certain time period. 

According to Prof Martie Smit, Head of the department, this is a reflection of the quality of research delivered by the department. “It is difficult and takes a lot of time and resources to publish in such high-impact journals.”

Contributing to their success in the department, is the work of their collaborators as well as the quality international postdoctoral researchers the department manages to attract with their emphasis on quality research.

Another highlight in the publication of these articles was that members of the department were corresponding authors of four of the five articles – meaning that the research was conducted in and driven from their laboratories, with UFS researchers taking primary responsibility for the preparation of the manuscripts and communicating with the editors of the journals.

Impacting society

Besides publishing in journals with high impact factors, these researchers are also making a difference to society. Prof Robert Bragg contributed to the study focusing on quality disinfectants. 

We are all aware of the danger of developing resistance to antibiotics. According to Prof Bragg, it is estimated that by 2050, 25 million people could be dying from antibiotic resistance-related bacterial infections per year. He says one of the best options to control diseases – not only bacterial diseases, but also viral diseases such as the Covid-19 outbreak – is good biosecurity and the use of good-quality disinfectants.

Researchers working on this study are trying to understand the development of resistance in bacteria to disinfectants. “This research group is currently investigating the ways in which bacteria become resistant to different high-quality disinfectants. The aim of this work is to discover new methods of resistance and then try to prevent bacteria from becoming resistant to commonly used disinfectants. One of the first aspects that needs investigation is to understand the methods of transfer of genetic information between bacteria. This work formed the basis of the review article written with master’s student Samantha McCarlie on transfer of genes that could code for disinfectant resistance in bacteria,” says Prof Bragg.

Studies about a nematode species discovered 1,3 km deep in a gold mine in Welkom and its ability to survive in extreme environments, made headlines about nine years ago. More extensive research has been performed on deep-space exploration of nematodes surviving extreme environments and were published in Nature Communications. Dr Mariana Erasmus, Assistant Director in the department and Technology Innovation Agency/UFS Saense Platform manager, says the study published in 2019 reveals these nematodes’ adaptation to heat and heat tolerance in an unusual ecosystem isolated from the surface biosphere. More studies on this can help humans learn how to adapt to a warming climate. 

TIA is an agency of the Department of Science and Innovation.

Three of the articles are from the Biocatalysis and Structural Biology group of Prof Dirk Opperman, Prof Martie Smit, and Dr Carmien Tolmie. Biocatalysis is a form of green chemistry that aims to produce chemicals in an environmentally friendly and sustainable manner. The research of the group focuses on using enzymes (proteins performing specialised chemical reactions) to insert an oxygen atom at a specific position in a starting material. Such reactions are difficult to perform using purely organic chemistry. 

The end products are value-added compounds of interest to, among others, the flavour and fragrance industry, which place a high premium on natural products. The work on the novel in‐chain hydroxylase was also patented internationally, because it can be used for the synthesis of a valuable flavour compound.
 
More to come

Besides the commitment of the team in Microbiology, it took multiple institutions, dedicated postdoctoral students, as well as time and money to publish this number of articles in high-impact journals in just over a year. With its 100-plus researchers varying from student researchers to NRF-rated scientists, everyone in the Department of Microbial, Biochemical and Food Biotechnology strives to produce high-quality research. 

And they promise, there is more to come. Watch this space …

In January 1, 2003, the Qwa-Qwa campus of the University of the North (Unin) was incorporated into the University of the Free State (UFS).

FREDERICK FOURIE

IN January 1, 2003, the Qwa-Qwa campus of the University of the North (Unin) was incorporated into the University of the Free State (UFS).

While this is merely the beginning of a long and complex process, it does represent a major milestone in overcoming the apartheid legacy in education, realising the anti-apartheid goal of a single non-racial university serving the Free State.

The incorporation is also part of the minister's broader restructuring of the higher education landscape in South Africa - a process which aims to reshape the ideologically driven legacy of the past.

In contrast to the past educational and social engineering that took place, the current process of incorporating the Qwa-Qwa campus of Unin into the UFS is informed by three fundamentally progressive policy objectives, clearly outlined in the education white paper 3: (A framework for the transformation of higher education):

To meet the demands of social justice to address the social and structural inequalities that characterise higher education.

To address the challenges of globalisation, in particular the role of knowledge and information processing in driving social and economic development.

To ensure that limited resources are effectively and efficiently utilised, given the competing and equally pressing priorities in other social sectors.

Besides informing the way the UFS is managing the current incorporation, these policy objectives have also informed the transformation of the UFS as an institution over the past five years.

In 2001, former president Nelson Mandela lauded the success of the UFS in managing this transformation, by describing the campus as a model of multiculturalism and multilingualism. This was at his acceptance of an honorary doctorate from the UFS.

Indeed our vision for the Qwa-Qwa campus as a branch of the UFS is exactly the same as it is for the main UFS campus - a model of transformation, academic excellence, community engagement and financial sustainability, building on the histories and strengths of both the Qwa-Qwa campus and the UFS (Bloemfontein campus).

Realising this vision will be a giant leap forward in establishing a unified higher education landscape in the Free State.

In more concrete terms, the UFS is working towards this vision by focusing on the following areas of intervention: access and equity; academic renewal; investment in facilities; and sound financial management.

These interventions are being made not to preserve any vestiges of privilege or superiority, but precisely to increase access for students from poor backgrounds and to promote equity and representivity among all staff.

The current growth phase of the UFS has seen student enrolment almost double over the past five years, in particular black students, who now constitute approximately 55 percent of the student population of nearly 18 000 (including off-campus and online students).

But it has not just been a numbers game. Our approach has been to ensure access with success.

Our admissions policy, coupled with the academic support and "career preparation" programmes we offer, have resulted in significant successes for students who otherwise would not have been allowed to study at a university.

This will be continued at Qwa-Qwa as well.

Our academic offerings too have undergone dramatic change. We have become the first university in the country to offer a degree programme based on the recognition of prior learning (RPL).

This is not just a matter of academic renewal but of access as well, especially for working adults in our country who were previously denied a university education.

As for the sound financial management of the UFS (including the Qwa-Qwa campus), this is being done not for the sake of saving a few rands and cents, but for the greater value to our society that comes from having sustainable institutions.

It is sustainable universities that can make long-term investments to fund employment equity, provide information technology for students, upgrade laboratories, construct new buildings, develop research capacity, and provide a safe environment for students and staff, as is happening now at the UFS.

As a result of such management, a practical benefit for prospective students at the Qwa-Qwa campus of the UFS will be lower academic fees in some cases compared with the Unin fees.

As is the case with all these processes, there are concerns from staff and students at Qwa-Qwa and the broader community of the region that the Qwa-Qwa campus serves.

To get the campus viable and to ensure its continuation in the short term, tough choices had to be made by the minister of education regarding which programmes to offer and fund.

But we have been encouraged by the community's understanding that these concerns can be addresed over time as the campus becomes financially viable.

Meetings between the top mangement of the UFS and community representatives, staff and students at Qwa-Qwa have laid the basis for building a climate of trust in such a complex process.

We should not be captives of the past divisions but build this new unified higher education landscape that can meet our country's developmental needs.

It should be a higher education landscape that is based on broadening access, promoting equity and social justice, developing academic excellence, and the effective and efficient management of scarce resources. This should be our common common objective.
