New yeasts to produce more flavoursome light beer

15.06.2010
The EU is investing EUR 3.4 million in a comprehensive research programme on yeast. The aim is to develop new products in the food industry, both in terms of new flavours and health-promoting probiotic products. Molecular biologist Jure Piskur from Lund University in Sweden is coordinating the entire research programme.

Yeast is an important ingredient in the production of various food products such as wine, beer cheese and sausage. In the past many different species of yeast were used in food production, in a process known as spontaneous fermentation, but nowadays only a small number of species are used.

In both the beer and wine industries, there is now a growing interest in making use of the variety of species of yeast. Different yeast species can give a different character to drinks and food products.

“For example, there is a great interest in producing light beer with more flavour, and we hope that new species of yeast can contribute to this”, says Professor Jure Piskur from the Department of Biology at Lund University in Sweden.

Yeast can also be useful in the creation of probiotic food products that have health benefits. There is high demand in this area from Europe’s increasingly health-conscious consumers.

Jure Piskur will coordinate the activities of the new consortium, Cornucopia, which has received EUR 3.4 million from the EU. A total of 11 partners are involved in the consortium – both universities and companies. In addition to Lund University, researchers from Denmark, Belgium, Italy, Spain, the Czech Republic and the Netherlands are also participating.

Business sector partners include the Danish brewer Carlsberg. The project will begin in January 2011 and continue for four years. Besides new facts about which yeasts may be of value to the food industry, the consortium will also run a research school that will produce a number of new researchers with expertise in the field.

Yeasts can be found everywhere in nature; on humans, animals, fruit – anywhere they have access to sugar. In total there are around 1 000 identified species in the world, but at least 10 000 new species are expected to be identified within the near future. Tens of species of yeast live on grapes alone.

As a molecular biologist, Jure Piskur has spent a long time studying yeast’s many millions of years of history. This group of organisms is very old and has therefore managed to develop a very large genetic variation between different species. It is this genetic wealth that gives such exciting potential for the food industry to explore.

“The difference in genetic make-up between different yeast species is actually larger than the difference between fish and humans”, says Jure Piskur.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
