Knowing yeast genome produces better wine

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.

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
