National Collection of Yeast Cultures
Encyclopedia
The National Collection of Yeast Cultures (NCYC) is a yeast
culture collection, established in 1951, and working under the Budapest Treaty
for the storage of over 4,000 yeast cultures. Located at the Institute of Food Research
in Norwich
, England
, since 1980. NCYC is part funded by the UK government but provides a commercial service to identify, store and supply yeast cultures. As well as the traditional baking and brewing yeast Saccharomyces cerevisiae
, this culture collection also contains hundreds of non-pathogenic yeast species. The yeasts are kept frozen under liquid nitrogen or freeze-dried in glass ampoules. To ensure the collection's safety, it is also duplicated and stored off site. Yeasts have been stored and revived successfully decades later.
