Torulaspora delbrueckii is a yeast species which is also known as Saccharomyces delbrueckii or Saccharomyces rosei (anamorph called Candida colliculosa).The genetic analyses have revealed that the various strains treated as T. Thus, the criteria of the species T. delbrueckii apparently needed some revision according to the type strain (the strain SANK 50118).
Torulaspora delbrueckii is a yeast species which is also known as Saccharomyces delbrueckii or Saccharomyces rosei (anamorph called Candida colliculosa). Torulaspora is a genus of ascomycetous yeasts in the family Saccharomycetaceae. delbrueckii actually represent different species (and belong even to different genera, like Debaryomyces, Saccharomyces and Candida).
One interesting usage of T. Delbrueckii (and quite possibly one or more of the similar Saccharomyces strains) is in brewing German-style wheat beers. During fermentation the yeast produces noticeable banana-esters and clove-like phenols which impart the distinct aroma typified by these beers. The yeast growth, viability rate of resting yeast cells, and the fermentation activity of Saccharomyces cerevisiae and Torulaspora delbrueckii in grape musts with high sugar contents can be increased by aeration.
