Today it is universally agreed that yeast classification requires a polyphasic approach including the study of cell morphology and physiology, followed by assignment to a given species through the use of one or more molecular techniques [i.e. nDNA-nDNA hybridization against type strains, determination of electrophoretic karyotypes by pulsed field gel electrophoresis (PFGE), or ribosomal DNA sequencing of the D1/D2 and ITS regions].

Accordingly, DBVPG Collection use molecular taxonomic approaches such as the sequencing of the D1/D2 domains belonging to the large subunit (LSU) of 26S rRNA gene and of Internal Transcribed Spacers (ITS 1 & 2 region) including the 5.8S rRNA gene to verify the accuracy of assignment of unknown yeast cultures. The ultimate scope is to make available to the scientific community study models comprising taxonomically certified yeast strains.

The taxonomic description of novel species is one of the scopes of DBVPG Collection.
