The Free State is currently one of the provinces in the country with the highest percentage of new tests that turn out positive for COVID-19. This also impacts on the staff and students at the University of the Free State (UFS), as the number of positive cases on the campuses has increased considerably during the past few weeks.  

The UFS experienced an increase of 47% in the number of students who tested positive from Level 2 of the national lockdown to Level 1. During the past few days, an increase of 21% in positive student cases has been experienced. In the case of staff, an increase of 34% in the number who tested positive occurred from Level 2 of the national lockdown to Level 1. Over  the past few days, an increase of 11% in positive cases has been experienced.

1. Adherence to national protocols and regulations

The safety, health, and well-being of staff and students remain a priority. Therefore, the university management is concerned about the rise in positive cases on the campuses and appeals to staff to adhere to the national protocols and regulations issued by the Ministers of Cooperative Governance and Traditional Affairs, Employment and Labour, Higher Education, Science and Innovation, and Health.   

It is important to note that non-adherence to certain of the national protocols and regulations is a criminal offence and is punishable by a fine or imprisonment of up to six months. By not adhering to national protocols and regulations, our staff is not only putting their own health at risk, but also the health of others.

2. Behaviour observed on campus  

The following behaviour has been observed among staff working on campus:
- Not adhering to social/physical distancing of 2 metres;
- Face-to-face contact without wearing masks (e.g. in boardrooms and tearooms, visiting each other in offices, etc);
- Not wearing a mask while moving on campus, as well as in buildings (except in the privacy of offices);
- Dishonesty during the screening process; and
- Non-compliance with isolation and quarantine guidelines.
Staff members are reminded that they may face disciplinary action if they do not adhere to the national COVID-19 protocols and regulations as issued by the different ministers. It is important that staff members be honest at all times during the screening process, as it has been observed that some staff members display some COVID-19-related symptoms but answer in the negative on the online screening app.

3. Reporting of positive COVID-19 cases
In terms of the directives issued by the Minister of Employment and Labour, the Minister of Health, and the Minister of Higher Education, Science and Innovation, the UFS is required to report all COVID-19 positive cases to the Department of Labour, the Department of Health, and the Department of Higher Education and Training.  All COVID-19 positive cases must thus be reported directly to the Senior Director: Human Resources (vjaarsj@ufs.ac.za) and Kovsie Health (johnr@ufs.ac.za) for further handling and reporting to the relevant government departments.

Please do not come to the campuses if you are experiencing any COVID-19-related symptoms and get tested as soon as possible.

Those staff members who test positive will receive the necessary advice from their medical practitioners and they can also contact Kovsie Health for assistance.

From wheat protein to perfect pizza

Barend Wentzel, an alumnus of the University of the Free State’s Department of Plant Sciences, is passionate about plant breeding. 

He literally eats and lives wheat proteins. In 1989 he initiated a breeding programme on arum lilies. “This breeding programme is at an advanced stage,” he said. Besides reading, playing the piano and accordion, Barend, due to the nature of his research at the Agricultural Research Council, also experiments with different types of ciabatta recipes made from sour dough. “I usually make my own pizza on Saturday evenings,” he said.

He is working at the Agricultural Research Council – Small Grain (ARC-SG) at the Wheat Quality Laboratory where he established a Cereal Chemistry Laboratory.

Complexity of flour quality

He explains that the focus of his research is on wheat protein composition. “The research conducted for my PhD study explains the complexity of flour quality to a certain extent, and it further emphasises the influence of the environment and genetic composition on selected baking characteristics. 

“Wheat protein can be divided into different types of protein fractions. These protein fractions contribute differently to dough properties and baking quality and the expression is affected by different components in the environment, including locality, rainfall and temperature. 

“Protein content alone does, however, not explain the variation in baking quality parameters, such as mixing time, dough strength and extensibility, and loaf volume.

“Several methods can be applied to quantify the different protein fractions. I am using high-performance liquid-chromatography (HPLC). The procedure entails the separation of a wheat protein extract through a column with chromatographic packing material. The injected sample is pumped through the column (known as the stationary phase) with a solvent (known as the mobile phase). The specific procedure, size-exclusion high-performance liquid-chromatography (SE-HPLC), is also used by the university’s Department of Plant Breeding, as well as in several international Cereal Chemistry Laboratories,” said Barend.

Dough strength and to loaf volume
“One of the highlights from the study was the positive contribution of the albumin and globulin protein fractions to dough strength and to loaf volume. The findings were wheat cultivar specific and the growing environment influenced the expression. The contribution of these protein fractions was much larger than previously reported for South African wheat cultivars,” said Barend. 
“Previous reports indicated that these protein fractions had a non-specific contribution to the gluten network during dough formation. The findings from this PhD justify further research on albumins and globulin proteins.” 

The Cereal Chemistry Laboratory at ARC-SG is involved in postgraduate student training under Barend’s guidance. He serves as co-promoter for several MSc and PhD students. He is also a collaborator on an international project with the International Maize and Wheat Improvement Centre (CIMMYT) in Mexico. Barend is furthermore working on improving wheat quality for processing and health purposes as a member of the expert working group of the International Wheat Initiative.
