Essential Science: Science makes beer last longer

Compared with many other alcoholic beverages, beer has a short expiry time, especially when compared with wine. To improve the holding time of ales and lagers, scientists have come up with a new, innovative process.

Mystery of unique probiotic yeast solved with CRISPR

Microbiologists have found discovered that the yeast Saccharomyces boulardii produces high amounts of acetic acid. By locating the genetic basis for this, the researchers could cancel the acetic acid production to find its probiotic effect.

Scientists show that yeast can make marijuana compounds

Researchers have demonstrated that a type of yeast can be turned into a cannabinoid-producing factory, offering a low-cost and environmentally-friendly means to make cannabis products.

Marijuana products produced by yeast - Appealing to non-smokers

With cannabis legal in a number of states and Canada, and even though pot is an agricultural product, not everyone wants to smoke it. So scientists have found a way to make pot's two most valuable compounds in a pot - using yeast.

Science of bread making reveals the secrets of taste and aroma

Paris - The art of bread making may be well established but there remains a lot to learn in terms of reproducing artisanal bread on a mass scale. This is where science comes in and new research reveals more about taste and aroma.

Essential Science: Can taking yeast extract boost brain function?

York - A new study suggests that yeast extract (as sold in the form of popular consumer products like Marmite) could boost brain function and lower the chances of a person developing dementia in later life.

Yeast found in guts of babies increases asthma risk

A study performed in Ecuador has shown a yeast in the gut of new babies to be a strong predictor that the babies will go on to develop asthma.

Group of engineering students hope to brew beer on the moon

A team of university students from UC San Diego have been shortlisted in a competition to conduct an experiment on the moon. If the team is selected, they will determine how yeast will react when beer is brewed on the lunar surface.

Yeast infection linked to mental illness

Infection with a common yeast can lead to mental health problems in some cases, according to new research. This is shown from analysis of patterns relating to psychiatric patients.

Remarkable history of coffee and chocolate yeast

Wild strains of yeast are necessary for the natural fermentations required for chocolate and coffee production. New genetic data indicates that the yeasts associated with coffee and cacao beans have had a special history.

Tracking down the extent of fungal diversity

Fungi are part of their own biological kingdom, yet little is known about the extent and diversity of the eukaryotic organisms. Experts think there are millions of undescribed fungi, found in different locations around the world.

Essential Science: Bio-designing yeast to improve biofuels

Scientists have engineered a new strain of yeast designed to create biofuel from switchgrass, turning the collected cellulosic biomass into an energy alternative. The process is described together with a review of biofuel progress.

Harnessing yeast to fight fungal pathogens

Yeast cells interacting in social communities are being studied to see if they can be harnessed to develop therapeutic strategies against pathogenic fungi.

Improving the flavor of lager beer

Lagers are often seen as the poor relation to ales in the flavor stakes, despite lager outselling ales by considerable amounts in the global beer market. Scientists are on a quest to offer a better range of lagers.

Cancer drug moved from rare plant to lab yeast

Researchers have manufactured a common cancer drug from a yeast in the lab. Previously the important drug could only be obtained from a rare and endangered plant in the wild.

The evolution of lager yeast charted

The key to making a good beer is a mix of the best ingredients, craft and the best yeast. In the beer world, lagers dominate the market. Researchers have been pondering the origins of the lager yeast.

Beer yeast creates the perfect chocolate

Making high quality chocolate is an art form and food technologists are continually experimenting with new processes. In a left-field move, one group has started to use the yeast from manufacturing beer.

Keeping the heat out of a good beer

Aberystwyth - One problem with making beer is preventing the yeast from getting too hot. This creates a conundrum because yeast generates its own heat, and the more effectively yeast works the more heat it generates.

Using yeasts to study human obesity

Researchers think that the study of yeasts can be particularly useful for gaining insights into human obesity. To explore this further, a biologist collaborated with a mathematician.

Slowing down the heat to make a good beer

Aberystwyth - One of the problems with making beer is that the yeast used generates a lot of heat and the heat, in turn, damages the yeast and this can lead to occasional bad tasting beer and loss of vital quantities of brewer’s yeast.

Remaking the world’s oldest beers from lost recipes

Helsinki - Brewers and scientists are reviewing beer recipes from clues that archaeologists have uncovered from an 1840’s-era shipwreck. The aim is to recreate an enticing beer from yesteryear.

Improving lager and making different types through new yeasts

Helsinki - Having fallen behind the craft beer movement, it could be time for tired old lager to be revitalized. Food technologists have been developing new hybrid yeasts for beer.

Turning whisky waste into fuel

A small independent company in Scotland is turning the waste products from the whisky industry into alcohol for use as a biofuel.

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.
