(Pink Sheets: DYAI)(“Dyadic”) announced today that it has joined the Industrial Platform of the Kluyver Centre for Genomics of Industrial Fermentation (the “Kluyver Centre”). This platform consists of both small to medium enterprise companies and multinationals involved in the field of industrial fermentation. Industrial Platform members link to the Kluyver Centre and benefit from direct, confidential access to results from the Kluyver Centre’s pre-commercialisation research activities. Membership will also enable Dyadic Netherlands to rapidly access an extended network of world class scientists.

By joining the Kluyver Centre’s Industrial Platform, Dyadic Netherlands will be actively involved in the Kluyver Centre’s research program entitled, “Filamentous Fungi for Proteins and Peptides,” but also intends to contribute to the centre by their experience in genomics of industrially relevant fungal strains. Jan Wery, Director Research and Development of Dyadic Netherlands stated: “As genomics research has become pivotal for the development of cutting edge enzyme technology at Dyadic, it is very important for us to stay connected to the state-of-the-art developments in this area. The Kluyver Centre is one of the outstanding consortia and provides this research and knowledge.” Wim van der Wilden, General Manager of Dyadic Netherlands added: “Our participation in the Kluyver Centre, in conjunction with our involvement in different European consortia such as the Eurofung Network, will support our goal of strengthening the position of Dyadic Netherlands in the Dutch biotech sector as well as the broader international biotech arena.”
