Knowing yeast genome produces better wine

04.06.2012
The yeast Dekkera bruxellensis plays an important role in the production of wine, as it can have either a positive or a negative impact on the taste.
Researchers at Lund University in Sweden, among others, have analyzed the yeast’s genome sequenced by the US Department of Energy Joint Genome Institute, giving wine producers the possibility to take control of the flavour development of the wine.

Yeasts are an important ingredient in the production of various types of food, for example wine, and they make a major contribution to the taste. One of these yeasts is Dekkera bruxellensis. It is responsible for the aromatic fingerprint in around half of red wines. Yet the yeast can cause huge financial losses for the wine industry – Dekkera bruxellensis can produce a phenolic flavour that is usually described as medicinal. In high concentrations it makes the wine undrinkable.

Despite the fact that Dekkera bruxellensis plays a significant role in the wine production process, relatively little research has been carried out on the yeast. However, in an international collaboration, researchers have now decoded the genome of Dekkera bruxellensis. The researchers have mainly studied the yeast’s genetic background and properties of relevance to food production.

“We now know a lot about how Dekkera bruxellensis acts in the aroma formation process during wine production. Wine producers can use this knowledge to their advantage”, says Professor Jure Piskur of the Department of Biology, Lund University.

In recent years, the wine industry has become increasingly interested in the properties of yeasts because they influence the character of the wine. The mapping of Dekkera bruxellensis’s genome can be used as a tool for wine producers worldwide to take control of flavour development.

“At the end of the day this could lead to more new and interesting wine tastes and greater financial savings for the wine industry”, says Jure Piskur.

The research results were published recently in the International Journal of Food Microbiology.

Im Focus: BAM@Hannover Messe: innovative 3D printing method for space flight

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...
