Yeast Identification Services:The NCYC provides a full service for identifying yeasts using either; standard chemotaxomomic analysis for full physiological profiling, or DNA sequencing for rapid species identification.
Chemotaxonomic analysis provides a full report on the characteristics of the strain identified and takes 3-4 weeks to complete from the time of inoculation of the test media. The chemotaxonomic identification methods used are those described in "The Yeasts. A Taxonomic Study", third edition (ed. N J W Kreger-van Rij, Elsevier, 1984). The tests carried out are broadly those listed in the NCYC database and inlude microscopic examination of morphology.
DNA sequence analysis (of the D1/D2 region of the 26S rDNA ) is recommended for rapid identification to species level and usually takes from 7-10 days from receipt of a culture. A species identification of the strain, including the derived D1/D2 sequence, is supplied upon completion of the work.
The cultures sent for identification should be pure and sent to NCYC securely packed, preferably on agar slopes. The NCYC can attempt isolation of individual strains from mixtures although this will involve an extra charge. Please contact the Collection manager for further details before sending cultures.
Any information already known about the properties of the culture, especially the environment from which it was isolated, should be sent with the culture. Cultures for identification are dealt with in rotation with those already received. Identification data are kept confidentially and cultures submitted for identification do not enter the open collection without permission from the depositor.
