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

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...

  Scientists have found a wild species of yeast that is the ancestor of that which is used to make cold-brewing ale, according to a US study published on Monday. The yeast -- called Saccharomyces eubayanus -- was found in the deep forests of South America´s Patagonia region, living on beech trees. Scientists say the yeast was key to the invention of the crisp-tasting German beer 600 years ago. It took five years of searching before scientists discovered, identified and...

New research suggests oxygen may have been made on Earth hundreds of millions of years before its debut in the atmosphere. MIT researchers found evidence that tiny aerobic organisms may have evolved to survive on extremely low levels of the gas in these undersea oases. Former MIT graduate student Jacob Waldbauer found while working with colleagues that yeast is able to produce key oxygen-dependent compounds, even with only minuscule puffs of the gas. The research suggests that early...
