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...

Findings could lead to more efficient biofuel production A strain of yeast that thrives on turning sugar cane into ethanol for biofuel has had its genome completely sequenced by researchers at Duke University Medical Center. "Understanding this microbe may enable more efficient biofuel production, and also will produce even more robust industrial organisms that are versatile and capable of producing advanced biofuels from non-food crops like switchgrass," said Lucas Argueso, Ph.D., lead...

RNAi, a key biochemical pathway in the genetic control networks of most organisms, has now been discovered in Saccharomyces castellii, a close relative of the prototypical budding yeast S. cerevisiae, and in Candida albicans, a common human pathogen. Budding yeasts are used in research as models for more complicated organisms, in industry to create beer and biofuels, and in pharmaceuticals to produce drugs and vaccines. The ability to study RNAi in yeast and to use RNAi to alter the yeast's...

Until now, the mode of action of nitrogen-containing bisphosphonate (N-BP) cancer drugs, used to relieve bone pain and to prevent skeletal complications in bone metastasis, has been almost entirely unknown. Researchers writing in BioMed Central's open access journal Genome Biology have used 'barcoded' yeast mutants to identify new biological processes involved in the cellular response to N-BPs, opening up opportunities for the development of new anticancer drugs. Daniela Delneri, from the...

Turning grape juice into wine is a stressful business for yeasts. Dr Agustin Aranda from the University of Valencia, Spain has identified the genes in yeast that enable it to respond to stress and is investigating ways to improve yeast performance by modifying its stress response mechanism. Speaking at the Society for General Microbiology meeting at Heriot-Watt University, Edinburgh, today (9 September), Dr Aranda described the stresses that wine yeasts undergo in the fermentation process....

LOS ANGELES, July 29 /PRNewswire/ -- Wade is an outlaw in the land of the free, a desperado of the great American Frontier -- a post-Darwinian, post-Freudian, post-Jungian, post-Einsteinian, post-Walt Disneyan, post-beat, post-hip, post-war, post-graduate, post-perspicuous persona non grata who is reconciled to spending his remaining days post-mortem in the sublime twilight of the impalpable underground, wrapped in cloistered communion among the lingering remains of gratefully dying flower...

Water is a crucial ingredient for life, but its level inside cells must be carefully regulated to maintain proper cell shape and size. In this week's issue of the open access journal PLoS Biology, scientists from the University of Gothenburg describe the highest resolution three-dimensional structure yet of a membrane protein, in this case of a protein channel known as an aquaporin that regulates water flow into and out of yeast cells. Virtually all living organisms use aquaporins to regulate...

A new species of yeast has been discovered deep in the Amazon jungle. In a paper published on-line in FEMS Yeast Research, IFR scientists and colleagues from Pontificia Universidad Cat³lica del Ecuador describe the novel characteristics of Candida carvajalis sp. nov. Yeasts have long been the powerhouses of our food and fermentation industries. Each new species adds to our knowledge of the yeast gene pool and even small genetic differences have the potential for major economic impact....

A robot scientist acting without human help has made its first real, albeit modest, discoveries, say researchers at the University of Cambridge. Named Adam, the robot is the creation of researchers at Cambridge and the United Kingdom's Aberystwyth University, New Scientist reported Friday. Without human assistance, Adam formulated and tested 20 hypotheses about gene coding for 13 enzymes in Saccharomyces cerevisiae, also known as brewer's yeast, said Ross King, a biologist at Aberystwyth who...

Waste sugar xylose fermented to ethanol through introduction of a single stepEckhard Boles, co-founder of the Swiss biofuel company Butalco GmbH and a professor at Goethe-University in Frankfurt, Germany, has discovered a new enzyme which teaches yeast cells to ferment xylose into ethanol. Xylose is an unused waste sugar in the cellulosic ethanol production process. The researchers have recently filed a patent application for their process.In industrial fermentation processes, the yeast...


Word of the Day
siliqua
  • A Roman unit of weight, 1⁄1728 of a pound.
  • A weight of four grains used in weighing gold and precious stones; a carat.
  • In anatomy, a formation suggesting a husk or pod.
  • The lowest unit in the Roman coinage, the twenty-fourth part of a solidus.
  • A coin of base silver of the Gothic and Lombard kings of Italy.
'Siliqua' comes from a Latin word meaning 'a pod.'
