UTEX B 430
Staurastrum orbiculare var. ralfsii

Due to the upcoming Winter Holiday closures, orders placed after November 15, 2017 for any Bulk Microalgae, Freshwater Diatoms, and strains kept in cryopreservation (cryo only-designated and NAABB strains), will not ship until early February 2018.



Algae Detail

UTEX Number: 430
Class: Chlorophyceae
Strain: Staurastrum orbiculare var. ralfsii
Media: Desmid Medium
Origin:
Description of Location:
Type Culture: No
Collection:
Isolation: K. Ondracek
Isolator Number: 4 Cosmarium
Deposition: CCAP (1952-5)
Relatives: CCAP 679/2 aka Prague 230; UTCC LB 40
Also Known As: S. orbiculare
Notes: identified by Cedercreutz

Cryopreservation Conditions

Temperature: -190 °C
Light source: Not Applicable
Intensity: Not Applicable
Periodicity: Not Applicable

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.
