Amazon River Found To Be A Metabolic Hotspot

April Flowers for redOrbit.com - Your Universe Online The Amazon rainforest is known as the lungs of the planet because it inhales carbon dioxide and exudes oxygen into the atmosphere. The plants of the forest use the carbon dioxide to promote leafy growth, which eventually falls to the ground and decomposes or washes away from the region´s plentiful rainfall. Until recently, the belief was that most of the rainforest´s carbon floated away on the Amazon River, ending up deep...

Stepping into unexplored territory in efforts to use corn stalks, grass and other non-food plants to make biofuels, scientists today described the discovery of a potential treasure-trove of candidate enzymes in fungi thriving in the feces and intestinal tracts of horses. They reported on these enzymes – the key to economical production of biofuels from non-food plant material – at the 245th National Meeting & Exposition of the American Chemical Society (ACS). More than...

When blessed with a resource in overwhelming abundance it´s generally a good idea to make valuable use of that resource. Lignocellulosic biomass is the most abundant organic material on Earth. For thousands of years it has been used as animal feed, and for the past two centuries has been a staple of the paper industry. This abundant resource, however, could also supply the sugars needed to produce advanced biofuels that can supplement or replace fossil fuels, providing several key...

High-Throughput Analytical Pyrolysis Tool Is Faster And More Precise
2013-03-05 13:43:19

National Renewable Energy Laboratory A screening tool from the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) eases and greatly quickens one of the thorniest tasks in the biofuels industry: determining cell wall chemistry to find plants with ideal genes. NREL's new High-Throughput Analytical Pyrolysis tool (HTAP) can thoroughly analyze hundreds of biomass samples a day and give an early look at the genotypes that are most worth pursuing. Analysis of a sample...

Digesting lignin, a highly stable polymer that accounts for up to a third of biomass, is a limiting step to producing a variety of biofuels. Researchers at Brown have figured out the microscopic chemical switch that allows Streptomyces bacteria to get to work, breaking lignin down into its constituent parts. Microorganisms that can break down plant biomass into the precursors of biodiesel or other commodity chemicals might one day be used to produce alternatives to petroleum. But the...

Turning lignin, a plant's structural "glue" and a byproduct of the paper and pulp industry, into something considerably more valuable is driving a research effort headed by Amit Naskar of Oak Ridge National Laboratory. In a cover article published in Green Chemistry, the research team describes a process that ultimately transforms the lignin byproduct into a thermoplastic - a polymer that becomes pliable above a specific temperature. Researchers accomplished this by reconstructing larger...

Word of the Day
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
