Drunken elephants: The marula fruit myth

...it is in season. Fallen marula fruit may naturally ferment to an ethanol content of approximately 3 percent after three or four days. However, elephants have shown a clear preference for marula fruit still on the tree. Disregarding a large fruit pit, the metabolism of alcohol over time, and the unlikelines...

Research highlights how bacteria produce energy

...neered the bacterium Bacillus subtilis to directly ferment glucose sugar to ethanol with a high (86%) yield. ...a quest to develop bacteria that can breakdown and ferment cellulose biomass directly to ethanol. "Currently ethanol is produced primarily from sugarcane or c...

Biofuels researcher searches for new sources

...sugars and also looking at microorganisms that can ferment the sugars into fuel. Daniel Kammen, director of the Renewable and Appropriate Energy Lab at the University of California at Berkeley, said in a recent email that rapid technological advances in the production of such cellulosic ethanol are contrib...

Parallel evolution: Proteins do it, too

...ive system similar to a cow's. Bacteria in the gut ferment the leaves and take up nutrients that are released in the process. The monkeys, in turn, digest the bacteria to recover the nutrients, such as protein and ribonucleic acid (RNA), a particularly important source of nitrogen in leaf eaters. Zhang focu...

Genomic comparison of lactic acid bacteria published

..., cocoa, and coffee are all enhanced by LAB, which ferment six-carbon sugars, or hexoses, to produce lactic acid. "DOE JGI's contribution to the whole study of lactic acid bacteria is simply immense," said David Mills, Associate Professor, Viticulture & Enology, University of California, Davis, and sen...

Super-fermenting fungus genome sequenced

...der. “Increasing the capacity of P. stipitis to ferment xylose and using this knowledge for improving xylose metabolism in other microbes, such as Saccharomyces cerevisiae, brewer’s yeast, offers a strategy for improved production of cellulosic ethanol,?said Eddy Rubin, DOE JGI Director. “In addition, th...

Genome sequencing reveals key to viable ethanol production

...arate steps to break down biomass into glucose and ferment the glucose into ethanol, as is currently done, Wu...orking on a way to make a bacterium break down and ferment plant biomass efficiently in just one step. Wu investigated C. thermocellum, which is a microorgan...
