Yeast News

Why does beer taste good?

One answer to this question could be “because it does,” but that doesn’t get to the heart of the matter. The answer is with yeast and the yeast aroma not only appeals to people, it has a particular attraction for fruit flies.

New beer developed, based on an 1840 shipwreck recipe

From an analysis of bottles of beer salvaged from the 1840s shipwreck found near the Åland Islands in 2010, food technologists are trying to re-create the original beer. To achieve this, they are studying some bacteria isolated from the bottles.

Yeast used to make morphine

Biologists have successfully introduced bacterial and poppy plant genes into yeast to manufacture morphine. The research is important because opiates are medically essential. However, current production via opium poppy leads to supply inefficiencies.

Good beers need new yeasts

Beer is the most widely consumed alcoholic beverage on the planet. Good beer requires good quality yeasts and researchers are continuing to hunt for new strains.

Baker’s yeast could help combat Parkinson’s

Researchers think that baker's yeast may have the potential for combating neurological conditions like Parkinson's and cancer.

Duckweed makes for a good biofuel source

Duckweed is a tiny floating plant and often seen as an unwanted weed. Now it seems as if the plant could have an economic value: as a source for biofuels.

Table sugar used to make a ‘sweet biofuel’

A research team has developed a new source of renewable energy: a biofuel made from genetically engineered yeast cells and ordinary table sugar. This yeast produces oils and fats, known as lipids, that can be used in place of petroleum-derived products.

Super yeast improves wine, but lowers alcohol content

Australian researchers have identified special yeast for wine making. The yeast produces a lower level of alcohol but also help to preserve and to enhance the flavor.

Super yeast increases ethanol yield

A research team have engineered a yeast to consume acetic acid, a previously unwanted by-product of the process of converting plant leaves, stems and other tissues into biofuels.

Beer genetically engineered to improve froth

Using the yeast used to make beer scientists to create the first gene for beer foam. The gene can be used to improve the frothy foam on beer to create beers that are more appealing to consumers.

Man makes beer from yeast found in his beard

A man has brewed a beer which was fermented using a yeast isolated from his own beard. The yeast has been cultivated to be used for brewing a clear, golden ale.

Can genetic modification make best quality wine?

Scientists have sequenced the genome of one of the yeasts used to make wine. By understanding more about which strains of yeasts make wine of the best quality it could be possible to genetically modify certain yeast to aid premium wine production.

'Cyborg' yeast, computer alter genes through feedback loop

Scientists at the Swiss Federal Institute of Technology in Zurich, Switzerland were able to activate a cybernetic "feedback loop" between a common baking and brewing yeast and a computer, to gain precise control over specific genes, the BBC reported.

Sexual selection in action, revealed thanks to yeast

Why have peacocks such elaborate tails, why have birds of paradise often such crippling plumage? Sexual selection is the answer, but how does sexual selection actually work? Thanks to the humble yeast, we may now be able to find the answer.

Saccharomyces cerevisiae is a species of yeast. It is perhaps the most useful yeast, having been instrumental to winemaking, baking, and brewing fro a 1000 years.
