UTEX 327
Prototheca portoricensis var. trisporus

Price Increase Notification: February 1, 2018

Beginning February 1, 2018, UTEX will need to increase the commercial pricing for UTEX's Living Algal Strains, Algae Express Strains, and Bulk Microalgae to help keep up with inflation and rising shipping costs. Pricing will not change for UTEX products and services not mentioned. Please visit our FAQ page for additional information or view the full announcement here.

*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: 327
Class: Chlorophyceae
Strain: Prototheca portoricensis var. trisporus
Media: Malt Medium
Origin:
Description of Location: thermophile (38çC)
Type Culture: No
Collection:
Isolation: B.K. Ashford
Isolator Number:
Deposition: CCAP (1952-5)
Relatives: SAG 263-4; CCAP 263/4 [dec.]
Also Known As: P. zopfii; P. trispora
Notes: pathogenic strain to CCAP from B.K. Ashford via Delft (Ashford et al. 1930); grown in the dark

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.
