Westerdijk Fungal Biodiversity Institute
Filamentous fungi and yeasts play an important role in our daily life, both as agents of spoilage in food and feed and as agents of disease and deterioration in building materials, artworks, museum objects, archives and a wide variety of other valuable items. The fundamental research of the Westerdijk Institute focusses on fungal biodiversity, ecology and biology in the widest sense, focusing on three priority areas, agriculture, human health, and industry. It is the leader in this field, but is also the centre of expertise, advising on mycological problems of a scientific, health-related or industrial nature. It offers various services including identification, applied research, consultancy, ordering of cultures and courses. Westerdijk Institute is an independent laboratory and research projects are carried out on a strictly confidential basis.
Fungi and Food Safety
Worldwide, the quantity of food products that is lost due to fungal spoilage is immense. This loss can be caused by post-harvest problems, in which fungi attack still-living fruits, vegetables and grains, but it can also arise in processed foods affected by spoilage fungi. The growth of fungi may result in off-flavours, discoloration and altered texture. What is not so readily visible, but is even more alarming is the formation of mycotoxins in contaminated foods and feeds. The Westerdijk Institute has been working on fungal problems since many decades and are the leading authorities in the mycological investigations of food, and beverages. We aim to assist you in ensuring the safety of your products. This is done by consultation on mycological problems, isolation and identification of fungi (incl. yeasts) from samples and carrying out research and surveys in the food sector.
Fungi in indoor environments
Fungal proliferation indoors is often related to leakage, flooding, condensation and humidity problems. Problems occur both in old and new buildings, and often arise after inferior renovation works, or after installation of tight insulation. Nowadays many problems occur worldwide with the large scale air-handling and -conditioning systems (HVAC). Fungal problems can occur in any home and working environments including libraries and archives. Westerdijk Institute has experience in analysing fungal problems in indoor environments (houses and buildings), including museums and archives. Our research has the aim to advise inhabitants or workers for adverse health complaints by identifying
fungi found on building material, surfaces or in the air.
