From the Department of Microbiology and Biochemistry, were from the left, front: Dr Mariana Erasmus, Prof Martie Smit, Samantha McCarlie; back: Dr Carmien Tolmie; Samantha McCarlie, Prof Dirk Opperman, and Prof Robert Bragg. 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 …

MBA Programme - Question And Answer Sheet - 27 May 2004
2004-05-27

1. WHAT MUST THE UNIVERSITY OF THE FREE STATE (UFS) DO TO GET FULL ACCREDITATION FOR THE MBA PROGRAMMES?

According to the Council on Higher Education’s (CHE) evaluation, the three MBA programmes of the UFS clearly and significantly contribute to students’ knowledge and skills, are relevant for the workplace, are appropriately resourced and have an appropriate internal and external programme environment. These programmes are the MBA General, the MBA in Health Care Management and the MBA in Entrepreneurship.

What the Council on Higher Education did find, was a few technical and administrative issues that need to be addressed.

This is why the three MBA programmes of the UFS received conditional accreditation – which in itself is a major achievement for the UFS’s School of Management, which was only four years old at the time of the evaluation.

The following breakdown gives one a sense of the mostly administrative nature of the conditions that have to be met before full accreditation is granted by the CHE:

a. A formal forum of stakeholders: The UFS is required to establish a more structured, inclusive process of review of its MBA programmes. This is an administrative formality already in process.

b. A work allocation model: According to the CHE this is required to regulate the workload of the teaching staff, particularly as student numbers grow, rather than via standard management processes as currently done.

c. Contractual agreements with part-time staff: The UFS is required to enter into formal agreements with part-time and contractual staff as all agreements are currently done on an informal and claim-basis. This is an administrative formality already in process.

d. A formal curriculum committee: According to the CHE, the School of Management had realised the need for a structure – other than the current Faculty Board - where all MBA lecturers can deliberate on the MBA programmes, and serve as a channel for faculty input, consultation and decision-making.

e. A system of external moderators: This need was already identified by the UFS and the system is to be implemented as early as July 2004.

f. A compulsory research component: The UFS is required to introduce a research component which will include the development of research skills for the business environment. The UFS management identified this need and has approved such a component - it is to take effect from January 2005. This is an insufficient element lacking in virtually all MBA programmes in South Africa.

g. Support programmes for learners having problems with numeracy: The UFS identified this as a need for academic support among some learners and has already developed such a programme which will be implemented from January 2005.

The majority of these conditions have been satisfied already and few remaining steps will take effect soon. It is for this reason that the UFS is confident that its three MBA programmes will soon receive full accreditation.

2. WHAT ACCREDITATION DOES THE UFS HAVE FOR ITS MBA PROGRAMME?

The UFS’s School of Management received conditional accreditation for its three MBA programmes.

Two levels of accreditation are awarded to tertiary institutions for their MBA programmes, namely full accreditation and conditional accreditation. When a programme does not comply with the minimum requirements regarding a small number of criteria, conditional accreditation is given. This can be rectified during the short or medium term.

3. IS THERE ANYTHING WRONG WITH THE ACADEMIC CORE OF THE UFS’s MBA PROGRAMMES?

No. The UFS is proud of its three MBA programmes’ reputation in the market and the positive feedback it receives from graduandi and their employers.

The MBA programmes of the UFS meet most of the minimum requirements of the evaluation process.

In particular, the key element of ‘teaching and learning’, which relates to the curriculum and content of the MBA programmes, is beyond question. In other words, the core of what is being taught in our MBA programmes is sound.

4. IS THE UFS’s MBA A WORTHWHILE QUALIFICATION?

Yes. Earlier this year, the School of Management – young as it is - was rated by employers as the best smaller business school in South Africa. This was based on a survey conducted by the Professional Management Review and reported in the Sunday Times Business Times, of 25 January 2004.

The UFS is committed to maintaining these high standards of quality, not only through compliance with the requirements of the CHE, but also through implementing its own quality assurance measures.

Another way in which we benchmark the quality of our MBA programmes is through the partnerships we have formed with institutions such as the DePaul University in Chicago and Kansas State University, both in the US, as well as the Robert Schuman University in France.

For this reason the UFS appreciates and supports the work of the CHE and welcomes its specific findings regarding the three MBA programmes.

It is understandable that the MBA review has caused some nervousness – not least among current MBA students throughout the country.

However, one principle that the UFS management is committed to is this: preparing all our students for a world of challenge and change. Without any doubt the MBA programme of the UFS is a solid preparation.
