National Park Service Special Collection

Microorganisms isolated from National Parks in the United States are now available through the National Park Service Special Collection at ATCC. These organisms offer a fascinating study of microbial ecology, from the hot springs of Yellowstone to the deserts of Big Bend National Park. Approximately 100 bacteria, fungi, and protozoa are currently available in this Special Collection, and the list will continue to grow.


The NPS strains require a special Material Transfer Agreement. The signed National Park Service MTA is required prior to shipment to customers proposing a non-commercial use. When you place an order, you will receive an e-mail or fax requesting you to print, complete, and fax the fully executed MTA to ATCC. Your order will be shipped to you when ATCC has received and reviewed the completed MTA. A separate agreement is required from the National Park Service for customers proposing a commercial use.


If you wish to deposit material in the National Park Service Special Collection please contact us.

If you have questions about the NPS Special Collection, contact us by e-mail.
