UTEX B 352
Heterococcus protonematoides

*Cryo Only cultures are strains that are not kept in active circulation and therefore require a 4-week minimum processing time period to thaw, grow out, and check viability before shipment.



Algae Detail

UTEX Number: 352
Class: Xanthophyceae
Strain: Heterococcus protonematoides
Media: Proteose Medium
Origin: Berner Oberland,
Description of Location: rocks
Type Culture: Yes
Collection:
Isolation: W. Vischer (1945)
Isolator Number: Basel 369
Deposition: CCAP (1952-5)
Relatives: CCAP 835/9; SAG 835-9
Also Known As:
Notes: 1947 to CCAP from W. Vischer; (Vischer 1945); Recovered 12/05 from CCAP

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.
