The University of the Free State-based National Control Laboratory for Biological Products (NCL) has maintained its esteemed status as a pharmaceutical testing laboratory after the South African Accreditation System (SANAS) further endorsed its quality-management systems as of high standard according to the International Standards Organisation’s requirements.

The Director of the NCL, Professor Derek Litthauer, said their laboratory – which is also approved by the World Health Organisation (WHO) – has again achieved the international testing standards. The cherry on top was that the NCL also received a certificate of Good Manufacturing Compliance (GMP) from the South African Health Products Regulatory Authority (SAHPRA). 

NCL is for Africa and the World 

Some of the factors that make the NCL an esteemed institution, is the fact that it is one of 12 laboratories worldwide to perform vaccine testing for the WHO; the NCL is the only vaccine-testing laboratory in the country that performs the final quality-control testing of all human vaccine batches marketed in South Africa on behalf of SAHPRA. 

For example, Prof Litthauer said that the influenza vaccine batches currently available on the South African market, were tested by the NCL for quality before authorising their release for sale to the public. This process is followed for all human vaccines used in SA.

 “In our role as vaccine-testing laboratory for the WHO, the NCL helps to ensure that the vaccines purchased through the WHO prequalification programme for international distribution to resource-limited countries, meet the high standards of quality, safety, and efficiency. 
The NCL was one of the first full members of the WHO NCL Network for Biologicals, which consists of full and associate members of regulatory authorities from more than 30 countries.

The NCL systems are world-class

Prof Litthauer said this achievement is recognition that their laboratory complies with specific international standards with respect to its quality-management system. 
“In practice, it means that the laboratory has all the quality systems in place to ensure high-quality test results. The GMP certification is a further step, meaning that laboratory testing is on the expected level for any pharmaceutical testing laboratory and manufacturer. It is a very strict certification.”

He further mentioned that the NCL is also licensed as a pharmaceutical manufacturer. “Although we do not manufacture, we have to comply with manufacturing standards.”
“It is rare for a pharmaceutical testing laboratory (such as the NCL) outside of a manufacturing context to qualify for both certifications. It means that the NCL complies with exceptionally strict standards for pharmaceutical labs anywhere in the world,” he said.
The certification provides the South African Health Products Regulatory Authority, the World Health Organisation, and other national control laboratories around the world, with the confidence that the test results from the NCL can be trusted.


There can be no compromise for quality 

The NCL Quality Assurance Manager, Mrs Marlena Visagie, said, “It is essential that the NCL complies with the highest international quality-assurance standards to ensure that all the lot-release operations, such as manufacturing review and quality testing, are performed in a reliable and reproducible manner.”

“There can be no compromise when it comes to the quality of medicines which are made available to the public,” she said.

“What makes this special, is that the NCL does not only comply with international ISO/IEC standards for pharmaceutical testing, but also with the additional GMP standards required by a pharmaceutical manufacturer. This means that the NCL must ensure that all its operations, including everything from the way documents are compiled and stored, to the maintenance of equipment and infrastructure as well as staff competency, are performed according to international guidelines.”

All NCL staff share vision of excellence

Prof Litthauer said the NCL has a staff complement of 15 technical, administrative, and support staff.  Four staff members have PhDs, and the rest of the technical staff have master’s or bachelor’s degrees or are trained as medical technologists. “At the moment, our biggest problem is to get enough suitable space to expand our testing,” he said.

Prof Litthauer said, “All the staff members at the NCL share the vision of excellence, which makes this kind of achievement possible.”
The NCL will host the third annual meeting of the WHO NCL Network in November of this year and will then be reassessed again by the WHO as part of the normal three-year cycle of assessments.

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.
