General organization of the DBVPG Collection


Globally, the DBVPG Collection ranks among the top 5 collections by number of deposited yeast strains. The main DBVPG objectives are the acquisition, classification, preservation and distribution of yeasts and yeast-like organisms.

All conserved strains have been classified by methods of conventional taxonomy, and the identification of most of them was confirmed by molecular techniques.

The value of a collection depends not only by the quality of the strains, but equally by the amount and accuracy of the data attached to them.  Thanks to the online catalogue of the DBVPG Collection it is possible to obtain not only the salient data of each deposited strain, but also a large number of other information such as: name of the most common synonyms of a species, geographical origin of the strain, biotech applications, DNA sequences, and existing literature. The abundance of information provided in the database allows a fast and efficient search for microorganisms that possessing the characteristics required by the users of the Collection.

The DBVPG research programs principally focus on the study of taxonomy, biodiversity and biotechnology of yeasts. Besides, DBVPG is a centre of expertise, advising on yeast properties of scientific and industrial nature. It offers various services including identifications, patent deposits and training courses. Upon request, research projects commissioned by third parties can be carried out on a strictly confidential base.

The DBVPG Collection

DBVPG Collection maintains more than 7,000 yeast and yeast-like cultures (representing a large percentage of the known species) in four separate sections:

Section 1 - Yeasts associated with alcohol fermentation industry

About 1,300 conserved strains of interest for oenological, brewing and bakery industry. Among them, about 1,100 cultures of Saccharomyces cerevisiae and related species have been taxonomically revised, screened for the presence of killer properties and evaluated for their oenological/technological characteristics in micro-fermentations at laboratory and pilot plant scale.

Section 2 - Yeasts from different environments

About 4,000 cultures isolated from over 300 different environmental and technological habitats during 60 years of ecological investigations. These belong to over 300 species of about 100 genera and are currently the object of large-scale screening surveys for their ability to produce novel molecules of food, pharmaceutical and cosmetic interest, as well as for the production of killer proteins.

Section 3 - Type strains and yeast cultures from other Collections

Over 1,600 certified cultures obtained through exchanges with other worldwide culture Collections. Many of them represent type strains of known species, that are reference strains used when the species was described for the first time.

Section 4 - Strains of yeast-like microorganisms

Over 300 cultures (in particular belonging to the genus Prototheca) from milk and barn-surrounding environmental samples (bedding, faeces, drinking or washing water, swabs) of dairy herds isolated from some European countries.
