At MIT, scientists have engineered
a new yeast strain that can survive in high levels of sugar and ethanol, producing 50 percent more ethanol than its natural cousins.
Verstrepen's team is continuing research to breed
new yeast strains with characteristics useful to industry, and will soon be adding a brewery to the lab to conduct further experiments.
Not exact matches
The team gene - edited
yeast to create a
new strain not so different from the
yeast used to brew beer — except, instead of producing alcohol, this one eats sugar and spits out collagen.
While in
yeast, the genome was altered by using
yeast genetic systems and then transplanted to produce a
new strain of M. mycoides.
However, the overall picture of diversity means there is limited scope for creating
new strains solely from wine
yeasts.
The study shows that VTT's method is suitable for the generation of
new lager
yeast strains and the creation of
new properties affecting the flavour of beer, as well as improving the beer production process.
New lager
yeast strains can now be generated entirely without genetic modification technology.
Scientists at the Australian Wine Research Institute are developing
new strains of
yeast that contribute different flavor profiles during wine fermentation, including boosted floral aromas.
Now, laboratories specializing in
yeast research are engaged in genomic mapping, hoping to create
new hybrids or
strains for different flavor effects — or sometimes just to help a particular brewery understand why a particular batch yielded a certain unintended flavor that the brewer would like to reproduce.
That concern is one reason the research team, led by Christina Smolke, a synthetic biologist at Stanford University in Palo Alto, California, stopped short of making a
yeast strain with the complete morphine pathway; medicinal drug makers also primarily use thebaine to make
new compounds.
Researchers hoping to mass produce a drug that combats resistant
strains of malaria have genetically engineered a powerful
new ally: a
yeast that synthesizes a precursor to the antimalarial drug artemisinin.
