Taqman real-time PCR for the detection and enumeration of Saccharomyces cerevisiae in wine.

Saccharomyces cerevisiae is the main yeast species responsible for wine fermentation; however, its presence during maturing or barrel-ageing can sometimes result in a reduction in the quality of wine by refermentation. In this work, we developed a quantitative real-time PCR (QPCR) for the rapid detection and quantification of S. cerevisiae in wine.
