Searchable Fields in strain database

Roughly 100 unpublished species have been discovered through sequencing of the D1/D2 region of the large (26S) ribosomal subunit. This database can be queried by Phaff collection personnel to find matches to your unpublished species.

In addition, the Phaff collection strain physiology database uses the powerful collection management program BioloMICS, and contains over 50 years of primarily unpublished strain characterization data, originally used for species identification and classification. This information is proving to be extremely useful for selection of strains with specific characteristics for use in academic or commercial research. For example, strains that assimilate a particular carbon source and grow at a certain temperature can be selected. Phaff collection personnel can search this database for strains on behalf of users of the collection.

Original data sheets have been located for over 4500 yeast strains, but approximately 2000 strains were either not assayed or the data has not been located. Please note that the types of assays performed changed over the years, so not all tests were performed on all strains. Additional screening of previously untested strains may identify additional candidates. Phaff collection personnel perform contract research to screen strains in the collection for particular properties.

The following lists describe the types of data in the newly expanded database. Most of this data is from the original Phaff lab data sheets. The list labeled "CBS data" contains information provided by the Centraalbureau voor Schimmelcultures, Utrecht, Netherlands, which they have gathered on approximately 700 strains that are present in both the Phaff collection and the CBS collection.
