UTEX Number: 2951
Class: Bangiophyceae (Red Algae)
Strain: Porphyra umbilicalis Kütz
Medium: Enriched Seawater Medium (ES)
Origin: Schoodic Peninsula, Maine, USA
Description of Location: Blueberry Hill; Mid-intertidal zone, a rocky shore often subjected to ice scour
GPS: 44° 20' 20.39" N, 68° 2' 42.03" W
Type Culture: No
Collection: Nicolas A. Blouin (4/3/08)
Isolation: Nicolas A. Blouin (4/11/08)
Isolator Number: P.um.1
Deposition: Susan H. Brawley
Relatives:
Also Known As: laver (common name)
Notes:

grown at 5 °C; grown at 5 °C at UTEX but also grows 5-15 °C at 50 µmol m-2 s-1 in bubbled or still conditions in PES. Material will turn green if nitrogen limited. This is Haplotype 1 (P.um.1) from the Brawley laboratory and is the strain being sequenced by the Joint Genome Institute. The material produces neutral spores for reproduction; (Blouin et al. 2007); (Jo et al. 2003); (Lui et al. 2004)

To reduce the risk of losing newly acquired cultures, it is highly recommended to initially duplicate the Collection's long-term maintenance conditions. Please note that these general maintenance conditions are not designed for optimal algal growth rates or large quantities. For information on the best growth conditions and media, consult other literature or conduct your own experiments. Once a stock culture is established, subcultures can be used to test other conditions.

You can find additional details on the long-term culture maintenance conditions on the Culture Maintenance Guides page.


Preparation of Living Algal Strains For Orders

Approximately 15 mL aliquots of the stock maintained as a liquid culture are transferred to screwcap tubes. Quality control (QC) checks are then completed via microscopy.

Cultures are sealed and packaged in a temperature-regulating mailer and shipped the same day.

UTEX makes no attempt to quantify the number of organisms or other characteristics of the culture and only guarantees the identity of the organism as specified in the strain history.
