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...

FINDINGS: Several structurally similar small molecules appear capable of protecting cells from alpha-synuclein toxicity, a hallmark of Parkinson's disease. RELEVANCE: Parkinson's disease is a neurodegenerative disorder characterized by tremors, muscle rigidity, and slowed movements. There is currently no cure for the disease, and current Parkinson's therapies only address disease symptoms, not the disease's cellular cause. Small molecules found to protect cells in multiple models of...

Mold and mildew may be doomed. Researchers are closer to understanding how these and other fungi grow. "Fungi have a big impact on our dinner plate," said Dr. Brian Shaw, Texas AgriLife Research plant pathologist. "We tend to think that getting food on the table is easy. But fungi are major disease-causing organisms for both plants and animals. With more research, we can find new ways to compete with them." Commonly known fungi are molds, mildews, mushrooms and yeast. Anyone who thinks humans...

With the introduction of a single bacterial gene into yeast, researchers from Delft University of Technology in the Netherlands achieved three improvements in bioethanol production from agricultural waste material: 'More ethanol, less acetate and elimination of the major by-product glycerol' This week the invention was published in the scientific journal Applied and Environmental Microbiology. Car fuel Bioethanol is made by the yeast Saccharomyces cerevisiae from sugars obtained from plant...

As global temperatures and energy costs continue to soar, renewable sources of energy will be key to a sustainable future. An attractive replacement for gasoline is biofuel, and in two studies published online in Genome Research (www.genome.org), scientists have analyzed the genome structures of bioethanol-producing microorganisms, uncovering genetic clues that will be critical in developing new technologies needed to implement production on a global scale. Bioethanol is produced from the...

Discovery Has Potential to Make Renewable Fuel Production More Efficient and Economical A team of researchers led by University of California, Riverside (UCR) Professor of Chemical Engineering Wilfred Chen has constructed for the first time a synthetic cellulosome in yeast, which is much more ethanol-tolerant than the bacteria in which these structures are normally found. The yeast cellulosome could enable efficient one-step "consolidated bioprocessing" by maximizing the catalytic efficiency...
