Lignin-Feasting Microbe Holds Promise for Biofuels

November 27th, 2013|Categories: Biofuels, Biomass, Energy, Facilities, JBEI, News, News & Events, Office of Science, Renewable Energy, Research & Capabilities, Transportation Energy|Tags: , , , , , , , , , , , |

Nature designed lignin, the tough woody polymer in the walls of plant cells, to bind and protect the cellulose sugars that plants use for energy. For this reason, lignin is a major challenge for those who would extract those same plant sugars and use them to make advanced biofuels. As part of their search for economic ways to overcome the lignin challenge, researchers at the Joint BioEnergy Institute (JBEI) have characterized the enzymatic activity of [...]

On February 15th, a 7,000 ton asteroid crashed into the Earth’s atmosphere, exploded, and fell to the ground in the Ural Mountains near Chelyabinsk, Russia. According to NASA, the meteor exploded with the power of 30 Hiroshima bombs and was the largest object to burst in the atmosphere since the Tunguska event of 1908—another Siberian impact that left few eyewitnesses or clues. One of those who searched for clues was Sandia physicist Mark Boslough (in [...]
