The sequence of an improtant wine yeast was determined. In many countries all over the world this yeast is responsible for spoilage of large quantities of wine and thus causes large economy losses to the wine producers. Our sequence represents an improtant tool to combat the negative aspects of this yeast during wine fermentation. For example, it can help to develop new approaches how to avoid that wine fermentation is taken over by D. bruxellensis and that off-flavours are produced.

We hereby review the recent data on the carbon metabolism in Saccharomycetaceae species and attempt to reconstruct the ancient environment, which could promote the evolution of alcoholic fermentation. We speculate that the first step toward the so-called fermentative lifestyle was the exploration of anaerobic niches resulting in an increased metabolic capacity to degrade sugar to ethanol. The strengthened glycolytic flow had in parallel a beneficial effect on the microbial competition outcome and later evolved as a "new" tool promoting the yeast competition ability under aerobic conditions. The basic aerobic alcoholic fermentation ability was subsequently "upgraded" in several lineages by evolving additional regulatory steps, such as glucose repression in the S. cerevisiae clade, to achieve a more precise metabolic control.

In this review we focus on the recently developed molecular and genetic tools, such as complete genome sequencing and transformation, to study and manipulate yeast Dekkera bruxellensis. We also focus on the areas that are particularly well explored in this yeast, such as the synthesis of off-flavours, yeast detection methods, carbon metabolism and evolutionary history.

Orchards and vineyards are interesting eco-systems with many important partners. We focused on the relationship between fruits, insects and microbes. We showed that there are many mutualistic relationships. For example, an important apple pest codling moth, needs yeast to survive in the apple and complete its development from larvae to adult. A detailed understanding of these relationships will help to develop new ways to combat important fruit-tree pests.
