Fees for Services
INVAM is an expensive operation. It includes wages of three core staff members (Morton, Wheeler, and an Assistant Curator) and student helpers in their collective efforts to setup, maintain, harvest, and store stocks grown in open pot cultures for 3-4 months at a time. Also included is maintenance and upgrades to greenhouse and growth rooms, equipment, supplies, and IT support services. The labor cost alone is estimated to be about $82,000 each year for accessioning, reaccessioning, and maintaining all of the holdings currently in the collection.
The National Science Foundation provides about 50% of the support
needed to operate the collection, with the remainder coming from West
Virginia University, the Davis College, and the fees listed on this
page. Ideally, NSF would like to see the
collection become completely self-sustainable. That will be difficult to
achieve unless there is a huge increase in the number of users, fees
are increased dramatically, or a combination of the two. Neither option
is viable at this time because the user base is not that large.
|Single strain culture (200 mL of whole inoculum or a vial of 1000-1200 spores)||$50/$100 each|
|A mixture of species in bulk quantity (one liter maximum)||$120/Liter|
|Morphological species ID (known species)||$25 each|
|LSU sequence ID (at least to genus)||$75/3-4 transformants|
|Infectivity assay (MIP)||$50/assay|
|Mycorrhizal assessment (%)||$30/root sample|
|DVD of hi-res images (collection species)||$60 each|
|Monospecific stock from submitted trap soil/culture||$200 each|
|Visit that involves using facilities||$250/week|
- Tiered fee structure is applied only to single strain cultures because of development costs: $50 for public/academia; $100 for industry/commercial use. There is no charge if a 1:1 culture exchange occurs. For requests from other culture collections, an exchange in stocks is required to promote sharing.
- The bulk inocula containing a species mixture is not available to industry users because such an approach is counterproductive in any long-term production scheme.
- Accuracy of species discrimination by LSU sequences is dependent on sample size of the sequence library, given the polymorphisms retained in the gene repeats.The INVAM library current consists of 412 LSU sequences of strains from 75 species, but with only 2-3 transformants (usually one per spore) for each strain. Because of the size of our collection, we are more focused on characterizing strain diversity rather than intra-strain variation.
- The fee structure for visitors is flexible. For example, students visiting only for training purposes generally are waived the fee as long as they are able to make some contribution (ideas, discussions of their projects, deposit of experimental stocks, etc.). Visits for 1-2 days are not charged any fee.
