Currently, almost all genera and species of Cyanidiophytina are maintained in culture, with particular emphasis on the genus Galdieria. Most of the strains have been isolated by the ACUF team, some have been deposited by other researchers or obtained from culture collections (D’Elia et al 2018). The majority of strains are available to the public. ACUF is an associate member of the MIRRI-IT JRU, (Italian Microbial Resource Research Infrastructure), which in turn is a country member of MIRRI-ERIC, the pan-European distributed Research Infrastructure for the preservation, systematic investigation, provision and valorization of microbial resources and biodiversity.  ACUF has been one of the Operative Units of the project SUS-MIRRI (2023-2025) funded by the National Recovery and Resilience Plan (PNRR) to increase the bioresources stored at MIRRI-IT Research Infrastructures (website of the project: https://www.sus-mirri.it/).
