Purdue University scientists have improved a strain of yeast that can produce more biofuel from cellulosic plant material by fermenting all five types of the plant's sugars. Nathan Mosier, an associate professor of agricultural and biological engineering; Miroslav Sedlak, a research assistant professor of agricultural and biological engineering; and Nancy Ho, a research professor of chemical engineering, used genes from a fungus to re-engineer a yeast strain Ho developed at Purdue. The new...

Scientists at the Department of Energy's Oak Ridge National Laboratory are improving strains of microorganisms used to convert cellulosic biomass into ethanol, including a recent modification that could improve the efficiency of the conversion process. Biofuels researchers and industrials have generated improved mutant microorganisms previously, but authors of a paper in the on-line Proceedings of the National Academy of Sciences identify a key Z. mobilis gene for the first time and show the...

A combination of enzymes and fermentation modifies bran structure and changes the bioavailability of the bioactive compound, according to new studies forming part of the European Union's large-scale HEALTHGRAIN project. Bioprocessing of bran has potential for making it a better ingredient for use in manufacturing nutritionally boosted cereal foods with high sensory quality. The health benefits of whole grain and grain dietary fibre are well documented, and dietary reecommendations worldwide...

Universit© de Montr©al scientists uncover mystery in journal Nature A mystery about the mechanism behind sexual mate selection has been resolved. According to a new study published in the journal Nature, Universit© de Montr©al researchers have discovered a molecular switch that becomes activated in response to a potential mate's signal. Simply put, an organism knows that a potential mate is close-by and healthy enough to mate. "This mating decision is controlled by a...

Scientists devise way to link complex traits with underlying genes Princeton University scientists have developed a new way to identify the hidden genetic material responsible for complex traits, a breakthrough they believe ultimately could lead to a deeper understanding of how multiple genes interact to produce everything from blue eyes to blood pressure problems. Writing in the April 15 edition of Nature, scientists led by Leonid Kruglyak, a professor in Princeton's Department of Ecology...

Engineering yeast to transform sugars more efficiently into alcohols could be an economically and environmentally sound way to replace fossil fuels, say scientists presenting at the Society for General Microbiology's spring meeting in Edinburgh on Sunday. Dr Christian Weber and Professor Eckhard Boles from Frankfurt University, Germany, have worked out how to modify yeast cells so that they successfully convert a wider range of sugars from plant waste such as wheat and rice straw into...

What better venue than San Francisco "“"“ sourdough capital of the world "“"“ to unveil a new natural sourdough ingredient that could replace conventional additives in a variety of other breads, while making them tastier and more healthful? And that's what scientists described Sunday March 21 at the American Chemical Society's 239th National Meeting, being held there. In the study, Maija Tenkanen, Ph.D., and colleagues reported discovery and use of a new strain of...

Cancer study yields results A researcher at Charles Drew University of Medicine and Science is investigating the potential use of non-pathogenic baker's yeast as a promising, natural therapy for cancer. Dr. Mamdooh Ghoneum presented his findings Tuesday, Feb. 2 at a special conference on "Cell Death Mechanism," sponsored by the American Association for Cancer Research (AACR) at the Omni San Diego Hotel in San Diego. "The central focus of the meeting is cell death regulation and how to mine...

Pistachios, almonds and other popular tree nuts might someday be routinely sprayed with a yeast called Pichia anomala. Laboratory and field studies by Agricultural Research Service (ARS) plant physiologist Sui-Sheng (Sylvia) Hua have shown that the yeast competes successfully for nutrients--and space to grow--that might otherwise be used by an unwanted mold, Aspergillus flavus. A. flavus and some other Aspergillus species can produce troublesome toxins known collectively as aflatoxins. Hua...
