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...

Johns Hopkins researchers create man-made system with built-in diversity generator In the quest to understand genomes–how they're built, how they're organized and what makes them work–a team of Johns Hopkins researchers has engineered from scratch a computer-designed yeast chromosome and incorporated into their creation a new system that lets scientists intentionally rearrange the yeast's genetic material. A report of their work appears September 14 as an Advance Online...

University of Illinois scientists have engineered a new strain of yeast that converts seaweed into biofuel in half the time it took just months ago. That's a process that's important outside the Corn Belt, said Yong-Su Jin, a University of Illinois assistant professor of microbial genomics and a faculty member in its Institute for Genomic Biology. "The key is the strain's ability to ferment cellobiose and galactose simultaneously, which makes the process much more efficient," Jin said....

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...

A new study has created an analog of what researchers think the first multicellular cooperation might have looked like, showing that yeast cells"”in an environment that requires them to work for their food"”grow and reproduce better in multicellular clumps than singly. A team of researchers, led by Harvard professor Andrew Murray, found that cells of brewer's yeast that clumped together were able more effectively to manipulate and absorb sugars in their environment than were...

Seventy percent of eight-month-old babies have a salt (sodium chloride) intake higher than the recommended UK maximum level, due to being fed salty and processed foods like yeast extract, gravy, baked beans and tinned spaghetti. Many are also given cows' milk, which has higher levels of salt than breast or formula milk, as their main drink despite recommendations that it should not be used in this way until babies are at least one year old. High levels of salt can damage developing kidneys,...

Research published in G3: Genes|Genomics|Genetics identifies the complete genome sequences and new laboratory strains of yeast available to the research community If you think yeast is most useful for beer and pizza crust, here's something else to chew on: a team of U.S. researchers has identified and compared the genetic codes for all known species of yeasts closely related to bakers' and brewers' yeast. This information, published in the Genetics Society of America's new open-access...

VISALIA, Calif., June 14, 2011 /PRNewswire/ -- EdeniQ, Inc., a California-based clean technology company serving the global biofuels industry, announced today that it has licensed yeast technology from the USDA Forest Products Laboratory (FPL) and the Wisconsin Alumni Research Foundation (WARF) associated with the fermentation of C5 sugars, such as xylose, to ethanol. The license marks the culmination of the 3-year Cooperative Research and Development Agreement (CRADA) between FPL and...

Mention vitamin D-fortified foods and most people think of milk, which has been fortified with the sunshine vitamin since the 1930s. A new episode in the American Chemical Society's (ACS) award-winning "Global Challenges/Chemistry Solutions" podcast series says that vitamin D-fortified bread could join milk as a mainstay for providing an essential nutrient that is difficult to get naturally in foods. The video points out that millions of people are unable to get enough vitamin D from food or...

The researcher in question is Nadia Skorupa Parachin and the secret of her technique is enzymes that she extracted from garden soil. If ethanol can be successfully made from xylose then ethanol production could increase by over 20 per cent "“ to the benefit of cheaper environmentally friendly fuel. Ethanol is manufactured by fermenting sugars from plant material. At present, xylose is not used, despite being the second most common type of sugar found in nature. Succeeding with xylose...
