(PhysOrg.com) -- A Texas Tech researcher said a recently patented chemical additive could break down the shield of certain types of antibiotic-resistant bacteria. http://www.physorg.com/news171814997.html Chemistry Thu, 10 Sep 2009 15:40:02 EST news171814997 (PhysOrg.com) -- In an article due to be published in Science, teams from the Institut Pasteurand the University of Limoges, associated with the CNRS and Inserm, decipherfor the first time the molecular mechanism that enables bacteria to acquiremultiresistance to antibiotics, and that even allows them to adapt thisresistance to their environment. This discovery highlights the difficulties thatwill have to be tackled by public health strategies if they are to address theproblems created by multiresistance. http://www.physorg.com/news162484449.html Biology Mon, 25 May 2009 15:34:57 EST news162484449 Bacterial resistance to antibiotics is one of medicine's most vexing challenges. In a study described in Nature Chemical Biology, researchers from Albert Einstein College of Medicine of Yeshiva University are developing a new generation of antibiotic compounds that do not provoke bacterial resistance. The compounds work against two notorious microbes: Vibrio cholerae, which causes cholera; and E. coli 0157:H7, the food contaminant that each year in the U.S. causes approximately 110,000 illnesses and 50 deaths. http://www.physorg.com/news156174057.html Chemistry Fri, 13 Mar 2009 14:44:40 EST news156174057 Eckhard 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. http://www.physorg.com/news154720922.html Chemistry Tue, 24 Feb 2009 18:02:26 EST news154720922 An international team of biochemists has discovered how an experimental drug unleashes its destructive force inside the bacteria that cause tuberculosis (TB). The finding could help scientists develop ways to treat dormant TB infections, and suggests a strategy for drug development against other bacteria as well. http://www.physorg.com/news147015355.html Medicine & Health Thu, 27 Nov 2008 13:35:55 EST news147015355
