Sequencing wine spoilage yeast

There is an article in Wine Spectator (Seen on the JGI feed) on sequencing the wine spoilage yeast bruxellensis (correct name is now Dekkera bruxellensis) which adds the not-so-excellent taste of “sweaty horse” to wines.  There is already some survey sequencing done by Ken Wolfe and Jurge Piskur’s groups so a full genome sequencing project will help work out how this yeast is able to out compete Saccharomyces and cause dramatic wine spoilage.  This is also relevant on the bio-fuel side since this yeast can also taint an ethanol bio-reactor.  It is an interesting ecology inside the wine bottle and this competition for resources can lead to bad tasting wine. The competition presumably originated in some form in the rotting fruit where these yeasts compete for space and use different approaches in their niche including the fermentation process which produces the revered ethanol by-product and helps establish a chemical-warfare driven landgrab.  The ethanol also helps prevent and of course this has implications for the Drosophila (Sophophora) flies that land there and eat yeast. They needed a good way to overcome the ethanol like the well studied Adh gene.
