About The Freshwater Diatoms (FD) Collection

David B. Czarnecki began collecting and studying freshwater diatoms as a graduate student. His collection moved with him to Loras College in 1984, where it was named and recognized universally among freshwater diatomists as the Loras College Freshwater Diatom Culture Collection. The Collection was maintained through grants to Loras College from the Iowa Science Foundation and the Iowa College Foundation.

In February 2006 Dr. Czarnecki requested that The Loras College Freshwater Diatom Collection be transferred from Loras College to UTEX. Loras College subsequently donated the entire collection to UTEX as a gift. Dr. Czarnecki died in May 2006. Strains from his collection that are maintained at UTEX will continue to be listed as the Loras College Freshwater Diatom Culture Collection in memory of Dave Czarnecki's service to the community of freshwater diatomists.

Strains that belong to the Freshwater Diatom Collection (designated 'FD' in UTEX number) will require a minimum of 4-weeks to grow out before shipment.


Cryopreservation Conditions

Temperature: -190 °C
Storage: Vapor phase of liquid nitrogen dewars

Cryopreservation stabilizes genomic integrity, preserves culture quality, minimizes maintenance costs and reduces the risk of catastrophic loss. A broad variety of techniques employed at the CCAP, at UTEX, and elsewhere, can be found in Day, J.G. and Brand, J.J. Cryopreservation Methods for Maintaining Microalgal Cultures, in Algal Culturing Techniques, ed. R. A. Andersen, Elsevier, Amsterdam, 2006. A relatively simple method that uses a minimum of specialized equipment, yet allows a large variety of microalgae to be cryopreserved with high viability, can be found on the Cryopreservation of Microalgae page.
