About The Snow Algae (SNO) Collection

The culture collection of snow algae maintained by Dr. Ron Hoham at Colgate University has been deposited in the Culture Collection of Algae at the University of Texas at Austin. The strains in this collection have all been isolated from snow and have been maintained at temperatures below 6 °C since their isolation. This collection includes isolates from eastern and western North America collected over a 35-year time period, and also includes isolates from Antarctica. Multiple isolates of the same taxon are maintained to permit research at the population level.

Most of the algae in this collection are members of Chlorophyta, but several strains are yellow-green algae (Xanthophyceae) and a few are golden algae (Chrysophyceae). Nearly all strains in the collection have been cryopreserved and in the future will be maintained at UTEX only at liquid nitrogen temperature.

These strains will survive transport at room temperature and that is the most reliable way to ship, but there is concern from the depositor that allowing them to warm during shipment may select for genotypes that are not as cold-adapted. Cultures will be shipped in a large styrofoam cooler box with ice pack.

General Long-Term Maintenance Conditions

Temperature: 20 °C
Light source: mix of warm-white & cool-white fluorescent lamps
Intensity: 3200 lux (maximum)
Periodicity: 12:12 Light/Dark Cycle

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

Agar cultures are transferred to fresh agar slants in 20-mm glass screwcap tubes. After quality control (QC) checks via microscopy are completed, the tubes are cultured under a diurnal light cycle for a minimum of three (3) days.

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.
