Scientists are 1 step closer to making more complex microscopic biological machines, following improvements in the way that they can 're-wire' DNA in yeast Scientists are one step closer to making more complex microscopic biological machines, following improvements in the way that they can "re-wire" DNA in yeast, according to research published today in the journal PLoS ONE. The researchers, from Imperial College London, have demonstrated a way of creating a new type of biological...

Promiscuous Yeast Hook Up In Wine-making Vats
2012-02-27 06:07:40

Humans aren't the only species that like to get busy with a glass of bubbly, according to researchers at the Stanford University School of Medicine. Turns out, the common baker's yeast has indulged in a frenzy of amorous frolicking in the fermentation vats of winemakers for hundreds, possibly thousands, of years, with interesting results. The unexpected promiscuity has made the lineage of many commercial and wild yeast strains difficult to trace. But there are also indications that such...

Irradiation with low-dose X-ray extends shelf life, reduces bacteria in fresh-cut asparagus As consumer demand for convenient, nutritious foods increases, pre-cut and packaged fruit and vegetables become more popular. Food producers are looking to science to discover new ways to safely extend the shelf life of these "minimally processed" products. A potential solution to vegetables' short market life may be the lie in x-ray irradiation, the latest ionizing irradiation technology currently...

UC Riverside entomologists explain why flies are attracted to beer and products of yeast fermentation Ever wondered why flies are attracted to beer? Entomologists at the University of California, Riverside have, and offer an explanation. They report that flies sense glycerol, a sweet-tasting compound that yeasts make during fermentation. "Insects use their taste system to glean important information about the quality and nutritive value of food sources," said Anupama Dahanukar, an...

Commanding Yeast Genes With Computers
2011-11-07 09:43:05

Scientists in Switzerland have managed to form a “feedback loop” between a computer and a common yeast, precisely controlling the switching on and off of specific genes. This could herald the ability to control biological processes, such as creating biofuel from microbes, Jason Palmer of BBC News reports. “The neat thing about this is that there are many people who have tried to do things like this by, for example, coding in the cell itself a synthetic circuit, putting...

Scientists have synthesized from scratch a so-called chromosome "arm"--one of the largest DNA molecules ever synthesized, and developed a new method for shuffling an organism's genetic deck Scientists have replaced all of the DNA in the arm of a yeast chromosome with computer-designed, synthetically produced DNA that is structurally distinct from its original DNA to produce a healthy yeast cell. (Yeast chromosomes are often depicted as bow tie-shaped--with each chromosome bearing two...

Cornstalks, wheat straw, and other rough, fibrous, harvest-time leftovers may soon be less expensive to convert into cellulosic ethanol, thanks to U.S. Department of Agriculture (USDA) scientists' studies of a promising new biorefinery yeast. The yeast–Saccharomyces cerevisiae strain NRRL Y-50049–successfully ferments plant sugars into cellulosic ethanol despite the stressful interference by problematic compounds such as furfural (2-furaldehyde) and HMF...
