The role of culture collections as an interface between providers and users: the example of yeasts

The importance and species diversity of yeasts in food production are described, including a listing of agricultural applications. Two yeast species were selected for case studies on distribution patterns from microbial culture collections: the high representation of Saccharomyces cerevisiae in culture collections enabled global comparison, while Dekkera bruxellensis deposits and distributions were analyzed from the perspective of a single culture collection. In conclusion, culture collections need to cover temporal gaps between deposit and application of strains. The further development of culture collections in countries of high but underexplored species diversity should facilitate the conservation and management of microbial resources.
