To limit this possibility, Torulaspora delbrueckii, in mixed or sequential culture with S. cerevisiae, has been proposed for fermentation (Bely et al., 2008 Ciani et ah, 2006 Lafon-Lafourcade et ah, 1981 Renault et ah, 2009). Although this yeast generates little alcohol, its application in mixed starter cultures is promising. It may also reduce the accumulation of other undesirable by-products, such as acetaldehyde, ethyl acetate, and acetoin.

Torulaspora delbrueckii (anamorp Candida colliculosa formerly Saccharomyces rosei) has a moderate tolerance to ethanol (<12.5 vol.% Table 8D.6) and produces wines which resemble those made with Saccharomyces cerevisiae. Production of higher alcohols is however highly variable and strain dependent. Because this yeast produces comparatively low concentrations of acetic acid, ethyl acetate, acetaldehyde and acetoin, its potential suitability for wine production has been suggested by several studies (Cabrera et al. 1988 Ciani and Ferraro 1998 Herraiz et al. 1990 ...

To distinguish yeasts that can produce ascospores from those that do not, mycologists use a dual taxonomy for classification. Unfortunately, the nomenclature for anamorph/teleomorph combinations is frequently different. Examples of sexual/asexual or teleomorph/anamorph yeasts include Dekkera/Brettanomyces, Metschnikowia pulcherrima/Candida ptdcher-rima, Hanseniaspora uvarum/Kloeckera apiculata, and Torulaspora delbrueckii/ Candida colliculosa. Some yeasts only exist in the anamorphic form because sporulation has yet to be demonstrated (e.g., Candida vini).
