Members holdings

Group(s) of biological resources stored in the collection: bacteria, yeasts, filamentous fungi, other fungus- like organisms.

PYCC is a research collection associated to the Applied Molecular Biosciences Unit (UCIBIO) and housed in the Department of Life Sciences at FCT/UNL. PYCC was founded in 1952 and is the oldest Portuguese Collection. It currently holds approximately 7000 strains, (6500 yeasts, 100 filamentous fungi and 500 bacteria). PYCC holdings can be assessed through the Collection’s online catalogue. Most of the current PYCC holdings have been authenticated through state-of-the-art molecular methods and all strains are cryopreserved at -150ºC. PYCC has a ISO 9001:2015 certification.
