Torulaspora delbrueckii is a ubiquitous yeast species with both wild and anthropic habitats. The type strain of T. delbrueckii is CBS 1146T, equivalent to CLIB 230 or ATCC 10662, etc.. The type strain of T. delbrueckii CBS 1146 T was recently sequenced, and is composed of 8 chromosomes in addition to a mitochondrial genome. T. delbrueckii was formerly known as Saccharomyces delbrueckii or Saccharomyces rosei or Saccharomyces roseus, and the anamorph is called Candida colliculosa (for a complete list of synonyms, see CBS's website).
T. delbrueckii is the most studied species of the Torulaspora genus that comprised 8 species to date, of which T. franciscae, T. pretoriensis, T. microellipsoides, T. globosa, T. indica,T. maleeae, and T. quercuum. The taxonomy of the Torulaspora genus is evolving rapidly, and the availability of molecular tools to discriminate Torulaspora species will help correcting errors in species assignments.
T. delbrueckii is isolated from several human bioprocesses, including the bread industry where some T. delbrueckii strains are commercialized for frozen dough applications. Other applications include food fermentations of silage, cocoa, olive or cucumber; distilled and traditional fermented beverage production including mescal,colonche,tequila,cider, strawberry tree fruits juice, sugarcane juice or kefir;dairy products’ fermentations like traditional cheeses and fermented milk.T. delbrueckii can be an opportunistic spoilage yeast for dairy products or soft drinks (fruit juices, etc.).T.delbrueckii colonizes several natural environments, ranging from soils, to plants, fruits and insects.T.delbrueckii is occasionally found as a clinical isolate, although not considered to be a human pathogen, a state described as opportunistic pathogen.
