Welcome to the
ARS Culture Collection (also known as the NRRL Collection)
website. The Collection is one of the largest public collections
of microorganisms in the world, currently containing approximately
96,000 strains of actinomycetes, bacteria, molds, and yeasts.
The collection is housed within the Bacterial
Foodborne Pathogens and Mycology Research Unit at the
National Center for Agricultural Utilization Research
in Peoria, Illinois.
This site provides information regarding
the public ("open") collection of strains, which
includes a searchable public access catalog for many of
the holdings of well characterized strains. The site also
provides information on the deposit and distribution of
strains maintained in the ARS Patent Culture Collection,
which is historically the first collection for strains related
to patent applications in the world. The holdings of the
patent strains, except for those that also serve as type
strains, are not searchable, but the website provides the
protocol for obtaining patent strains that are released
to the scientific public.
A number of important
endangered collections, including the Howard Dulmage collection
of insecticidal Bacillus strains, the International
Streptomyces Project (ISP) collection and the Jack
Fell collection of marine yeasts, have been accessioned
into the ARS Culture Collection and may be found in the
online catalog. Several other endangered collections, such
as the U. S. Army Quartermaster Collection of Fungi, are
held here for safe-keeping but are not accessioned into
the ARS Culture Collection.
online catalog of strains permits users to request strains
from search results. Effort
is being made to ensure that strains having NRRL accession
numbers that are present in the published literature can
be found in the online catalog. Please note that selections
from each page of the search results must be added to the
shopping cart before moving to a new page. Each
request is limited to 24 strains, the limit to a given laboratory
for a given calender year and must conform to the
ARS Culture Collection
distribution policies. Patent strains still must be
requested in writing from Mr.
James Swezey. The APHIS permits for distribution of
strains pathogenic to plants or animals within the US can
be uploaded in digtial format during the strain selection
process. International requests for these strains also still
require either the appropriate national importation permit
or documentation that no permit is needed, and these are
to be uploaded during the request process. Inquiries for
strains not listed in the online catalog but for which you
have an NRRL accession number should also be directed to
Mr. James Swezey.
Please Note (June 7, 2013):
Because shipping costs have escalated drastically in the past month,
thus making it impossible for the Collection to continue to underwrite
this expense, the Collection Manager will be requesting (by email) a
prepaid shipping label from all requestors from this time foward.
An updated webserver will be deployed in the near future and this
process will be automated as part of the checkout procedure. Our
thanks for your understanding and cooperation.
