The Department of Animal Science at the University of the Free State (UFS) walked away with numerous awards at the 52nd congress of the South African Society for Animal Science (SASAS).

Dr Foch de Witt, Senior Lecturer in the department, explains that the SASAS congress is an annual event where scientists, academics, students, and various industry role players come together to share the latest research findings regarding different aspects of animal science and production. 

Acknowledging greatness

The SASAS Gold Medal was awarded to Prof Michiel Scholtz, affiliated professor in the department. “He was presented with this award for his honourable lifelong service to animal science. His scientific contributions and achievements have been recognised as exceptionally meritorious by both national and international animal scientists,” says Prof Frikkie Neser, Head of the Department of Animal Science.

Andries van der Merwe, a postgraduate student, received the SASAS Student Postgraduate Merit Award. According to Prof Neser, this is an annual national merit award to postgraduate students for exceptional academic achievement in Animal Science during undergraduate studies at any South African university.

Dr Sinobongo Mdyogolo, a PhD student of Prof Neser, was presented with the SASAS Bronze Medal in respect of her PhD achievements in the research and technology transfer categories. This is the highest honour a student can get after completion of their PhD degree.

During the SASAS congress, a total of 22 oral and poster contributions were delivered by staff and students from the Department of Animal Science.

A great networking opportunity 

Another highlight for the department was when three of its students – Carina le Roux, Ofhani Mavhungu, and Andries van der Merwe – participated in and won the SASAS national student quiz. Team UFS was one of 13 student teams from various tertiary institutions participating in the competition. The external panel of judges complemented the team on how they integrated theoretical principles in a practical and applied manner.

According to Dr De Witt, UFS Animal Science graduates compare very favourably with other students from tertiary institutions in South Africa. “Many of our students seek employment in the animal feed industry and they excel in their professional career development. It is clear that the curriculum updates of the past few years were successful in ensuring that students are able to integrate theoretical and practical concepts in an applied manner – a skill that is sought after in the industry,” he says. 

He also believes that an event such as the SASAS congress is an ideal network opportunity where students can get exposure to congress presentations, while having the opportunity to meet potential employers and/or sponsors.

“The SASAS congress creates a platform for students to measure themselves in terms of scientific development and career preparedness by interacting directly with other students from different tertiary institutions as well as industry members. Exposure to events such as this furthermore prepares them for their professional registration with the South African Council for Natural Scientific Professions (SACNASP),” adds Dr De Witt.

Extending new discoveries in the deep subsurface – UFS paper published in Nature Communications
2015-11-30



Scanning electron microscopy of some of the Eukarya recovered from two different mines. (a) Dochmiotrema sp. (Plathyelminthes), (b) A. hemprichi (Annelida), (c) Mylonchulus brachyurus (Nematoda), (d) Amphiascoides (Arthropoda). Scale bar, 50 µm (a,b), 100 µm (c), 20 µm (d).

Following the discovery of the first Eukarya in the deep subsurface (Nature, 2010) by a research group from the Department of Microbial, Biochemical, and Food Biotechnology at the University of the Free State (UFS) and their international collaborators, intense interest has developed in understanding the diversity of more complex organisms living in these extreme environments.

Prof Gaetan Borgonie from Extreme Life Isyensya, together with a group of UFS researchers, took this research further, resulting in a paper on this research released in Nature Communications – impact factor 11.47.  This paper is an extension of the first reports of more complex life at great depths, and their abilities to survive these harsh conditions.

Ten authors from the UFS contributed with the array of expertise needed to define this discovery. The group was supported by staff from the different mining groups, long-term leading collaborators from the USA and Canada, and the idea specialist driver of the paper, Prof Borganie.

“After a sampling campaign that lasted more than two years, we identified that Platyhelminthes, Rotifera, Annelida and Arthropoda are thriving at 1.4 km depths in fissure water up to 12,000-years old in the South African mines of Driefontein and Kopanang,” said Prof Borgonie, who was appointed as associated researcher in the Department of Microbial, Biochemical, and Food Biotechnology.

This paper really opens a “can of worms” so to speak. According to Prof Esta van Heerden from the Department of Microbial, Biochemical and Food Biotechnology at the UFS they extended to define protozoa and fungi. “However, they are present in low numbers,” she said.

Characterisation of the different species reveals that many are opportunistic organisms. In house-adapted video equipment was used to film inside the fissure for the home of the organisms.

This is the first-known study to demonstrate the in situ distribution of biofilms on fissure rock faces using video documentation. Calculations suggest that food, not dissolved oxygen, is the limiting factor for population growth. The discovery of a group of complex multicellular organisms in the underground has important implications for the search for life on other planets in our solar system.
