Without fungi and microbes to break down dead trees and leaf litter in nature, the forest floor might look like a scene from TV's "Hoarders." Massive-scale genome sequencing projects supported by the U.S. Department of Energy (DOE) and being carried out at the DOE Joint Genome Institute (JGI) highlight the importance of learning how the cellulose, hemicellulose and lignin that serve as a plant's infrastructure can be broken down by these forest organisms to extract needed nutrients. Among...

A  class of chemical compounds used for flavor and fragrance may one day become a clean, renewable resource with which to fuel our automobiles. U.S. Department of Energy researchers have modified the E. Coli bacteria to create large quantities of methyl ketone from glucose. First tests of this methyl ketone show very high cetane numbers. Cetane is a fuel rating system for diesel fuel, similar to octane ratings for gasoline. This makes the methyl ketones a viable candidate for production...

Discovery paves the way for new synthesis of antibiotics Researchers working at the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory have used powerful X-rays to help decipher how certain natural antibiotics defy a longstanding set of chemical rules — a mechanism that has baffled organic chemists for decades. Their result, reported today in Nature, details how five carbon atoms and one oxygen atom in the structure of lasalocid, a natural antibiotic produced...
