Algae Details

UTEX Number: 1061
Class: Chlorophyceae
Strain: Chlamydomonas smithii
Media: Soil Extract Medium
Origin: Santa Cruz, California, USA
Description of Location: soil
Type Culture: Yes
Collection: G.A. Zebtmeyer (12/46)
Isolation: G.M. Smith (C-3 684c(+))
Isolator Number: 9
Deposition: R. Hoshaw
Relatives: SAG 53.72; CGC CC-1379; CGC CC-1372
Also Known As: Chlamydomonas reinhardtii [E&S]
Notes: heterothallic, crosses with UTEX 1062 & 90, (Hoshaw & Ettl 1966); 1061 is mating type minus, the original error in mating type identification can be attributed to the early misidentification of the mating types of IUCC 89 and 90, which were used in the study (E. Harris 1984, pers. comm.); no detectable hydrogen photoproduction (Brand et al. 1989); (Prí_schold et al. 2005)

Strains that are maintained only in cryopreservation (designated 'cryo only') 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.

Preparation of Strains Maintained Only In Cryopreservation For Orders

Strains that are maintained only in cryopreservation (cryo only) require a minimum of 4-weeks to thaw, grow out, and check viability before shipment. An estimated shipping date will be emailed when purchased. Updates via email will be sent if the strain is ready sooner or needs to be delayed further.

One tube of agar or liquid culture constitutes an order for a single culture of a single strain of living algae. UTEX makes no attempt to quantify the number of organisms or other characteristics of the culture. UTEX only guarantees the identity of the organism as specified in the strain history.
