The Industrial Yeasts Collection DBVPG is an academic biological resource centre (BRC) affiliated to ECCO (European Culture Collection Organization) and WFCC (World Federation of Culture Collections. 

The DBVPG Collection is specialized in the study and ex-situ conservation of yeasts and yeast-like microorganisms and offers biological products and services to the international scientific community and to other private Institutions

The main DBVPG objectives are the acquisition, classification, preservation and distribution of cultures of yeast and yeast-like organisms.

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 problems of an environmental or industrial nature.

DBVPG maintains about 6,000 yeast and yeast-like cultures representing a large percentage of the known species in four separate sections:

Section ONE - Yeasts associated with the 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 enological/technological characteristics in microfermentations at laboratory and pilot plant scale.

Section TWO - Yeasts from different environments
About 2,700 cultures isolated from over 300 different environmental and food-associated habitats during 60 years of ecological surveys. These belong to over 150 species of 50 genera, and are currently the object of large-scale screening surveys for the ability to produce novel molecules of food, pharmaceutical and cosmetic interest as well as for the presence of killer proteins.

Section THREE - Type strains and certified yeast cultures from other Collections
Over 1,600 certified cultures obtained through exchanges with other certified culture Collections.

Section FOUR - Strains of yeast-like microorganisms
Over 300 cultures (in particular belonging to the genus Prototheca) from milk and barn-surrounding environmental samples (bedding, feces, drinking or washing water, swabs) of dairy herds from some European countries.
