Jon Kehrer
Jon Kehrer is a prolific academic and scholar. He also spent a few years teaching English in the Middle East.

It was a former professor who influenced American scholar Jon Kehrer to further his academic journey with the Department of Hebrew at the University of the Free State (UFS). And it was at the UFS where he recently graduated cum laude with a master’s degree in Hebrew, and was named recipient of the Dean’s Medal. 

Although he never expected to receive the Dean’s Medal, he is very glad – and somewhat relieved – that his dissertation made it through the examiners. “I never anticipated receiving this award. It makes me even more grateful for the strong Hebrew Department at UFS, and their rigorous standards for their students,” Kehrer says. 

“I wish I had been able to attend the graduation ceremony, but the circumstances of the semester just did not allow it.” Kehrer is currently teaching in the areas of the Old Testament and Biblical Languages at the Ozark Christian College (OCC) in Missouri, USA. In addition to his UFS qualifications Kehrer also holds a Bachelor of Theology qualification from the OCC. “I love the opportunity to invest in students and help them see new perspectives,” he says. 

UFS Hebrew a firm foundation for a solid academic career  

“I was looking for a high-quality and challenging programme that was flexible, especially since I work full-time and have a large family,” Kehrer says, as he recalls how he initially decided to become part of the UFS. He remembers fondly how Dr Kevin Chau, senior lecturer in Hebrew at the UFS, motivated and supported him when he first enrolled for the BA Honours programme. 

It is also a testament that the Department of Hebrew has made an impact internationally for the quality of its academic offerings. “Dr Chau helped me to think about how what I was learning would have an impact on my research and teaching in the future, and he was always quick to provide thorough and constructive feedback on my work,” Kehrer says.  

Once enrolled for the master’s programme it was initially difficult to know which direction to pursue and what topic to research, but the guidance and support of his two advisors, Prof Cynthia Miller-Naude and Prof Jacobus Naude, was “very helpful”.

“They never dictated what paths I should pursue, but they listened carefully and provided expert guidance to help me choose the path that would best suit my interests and the needs of the field,” he says. 

It was this support from the Department of Hebrew and its excellent reputation that came full circle when Kehrer was named Dean’s Medal recipient for achieving the highest marks of any student in a master’s qualification in the UFS Faculty of The Humanities. 

Dissertation a closer look at verbs in Biblical Hebrew 

His dissertation focused on Biblical Hebrew and how the object of a verb appears in various ways. “Sometimes an object appears by itself, but sometimes it can have a preposition or a two-consonant Biblical Hebrew particle along with it. Many Bible translations treat all these objects the same,” he says. “I wanted to try to understand why these variations occurred, so I looked at how different sentence elements might contribute to the variation. It was a fascinating study!” 
 
Kehrer believes it is important for university students to continue studying classical subjects like Hebrew. “I think we can all learn much from those who have gone before us, and so much wisdom and insight is connected to these ancient Biblical Hebrew texts, texts that would be inaccessible to us without translation,” he says. 

“I also think classical disciplines can help train students to think well and to read critically – essential skills for living in today’s ever-changing world.”

Mushrooms, from gourmet food for humans to fodder for animals

Mushrooms have so many medicinal applications that humans have a substance in hand to promote long healthy lives. And it is not only humans who benefit from these macrofungi growing mostly in dark spaces.

“The substrate applied for growing the mushrooms can be used as animal fodder. Keeping all the medicinal values intact, these are transferred to feed goats as a supplement to their daily diet,” said Prof Bennie Viljoen, researcher in the Department of Microbial, Biochemical and Food Biotechnology at the UFS.

Curiosity and a humble start
“The entire mushroom project started two years ago as a sideline of curiosity to grow edible gourmet mushrooms for my own consumption. I was also intrigued by a friend who ate these mushrooms in their dried form to support his immune system, claiming he never gets sick. The sideline quickly changed when we discovered the interesting world of mushrooms and postgraduate students became involved.

“Since these humble beginnings we have rapidly expanded with the financial help of the Technology Transfer Office to a small enterprise with zero waste,” said Prof Viljoen. The research group also has many collaborators in the industry with full support from a nutraceutical company, an animal feed company and a mushroom growers’ association.

Prof Viljoen and his team’s mushroom research has various aspects.

Growing the tastiest edible mushrooms possible
“We are growing gourmet mushrooms on agricultural waste under controlled environmental conditions to achieve the tastiest edible mushrooms possible. This group of mushrooms is comprised of the King, Pink, Golden, Grey, Blue and Brown Oysters. Other than the research results we have obtained, this part is mainly governed by the postgraduate students running it as a business with the intention to share in the profit from excess mushrooms because they lack research bursaries. The mushrooms are sold to restaurants and food markets at weekends,” said Prof Viljoen.

Natural alternative for the treatment of various ailments
“The second entity of research encompasses the growth and application of medicinal mushrooms. Throughout history, mushrooms have been used as a natural alternative for the treatment of various ailments. Nowadays, macrofungi are known to be a source of bioactive compounds of medicinal value. These include prevention or alleviation of heart disease, inhibition of platelet aggregation, reduction of blood glucose levels, reduction of blood cholesterol and the prevention or alleviation of infections caused by bacterial, viral, fungal and parasitic pathogens. All of these properties can be enjoyed by capsulation of liquid concentrates or dried powdered mushrooms, as we recently confirmed by trial efforts which are defined as mushroom nutriceuticals,” he said.

Their research focuses on six different medicinal genera, each with specific medicinal attributes:
1.    Maitake: the most dominant property exhibited by this specific mushroom is the reduction of blood pressure as well as cholesterol. Other medicinal properties include anticancer, antidiabetic and immunomodulating while it may also improve the health of HIV patients.
2.    The Turkey Tail mushroom is known for its activity against various tumours and viruses as well as its antioxidant properties.
3.    Shiitake mushrooms have antioxidant properties and are capable of lowering blood serum cholesterol (BSC). The mushroom produces a water-soluble polysaccharide, lentinan, considered to be responsible for anticancer, antimicrobial and antitumour properties.
4.    The Grey Oyster mushroom has medicinal properties such as anticholesterol, antidiabetic, antimicrobial, antioxidant, antitumour and immunomodulatory properties.
5.    Recently there has been an increased interest in the Lion’s Mane mushroom which contains nerve growth factors (NGF) and may be applied as a possible treatment of Alzheimer’s disease as this compound seems to have the ability to re-grow and rebuild myelin by stimulating neurons.
6.    Reishi mushrooms are considered to be the mushrooms with the most medicinal properties due to their enhancing health effects such as treatment of cancer, as well as increasing longevity, resistance and recovery from diseases.

Valuable entity for the agricultural sector
Another research focus is the bio-mushroom application phenome, to break down trees growing as encroaching plants. This research is potentially very valuable for the agricultural sector in the areas where Acacia is an encroaching problem. With this process, waste products are upgraded to a usable state. “It is therefore, possible to convert woody biomass with a low digestibility and limited availability of nutrients into high-quality animal fodder. By carefully selecting the right combination of fungus species to ferment agro-wastes, a whole host of advantages could become inherently part of the substrate. Mushrooms could become a biotechnological tool used to ‘inject’ the substrate that will be fed to animals with nutrition and/or medicine as the need and situation dictates,” said Prof Viljoen.
