A bacterium causing an epidemic among catfish farms in the southeastern United States is closely related to organisms found in diseased grass carp in China, according to researchers at Auburn University in Alabama and three other institutions. The study, published this week in mBio®, the online ... Read More
The promise of affordable transportation fuels from biomass—a sustainable, carbon neutral route to American energy independence—has been left perpetually on hold by the economics of the conversion process. New research from the University of Georgia has overcome this hurdle allowing the direct c... Read More
Researchers at the University of Tübingen have discovered a microscopic fungus which promotes growth in certain plants. "This fungus, native to Europe, is an organic fertilizer with the potential to increase yields of crops such as wheat and maize," says Sigisfredo Garnica of the Institute of Ev... Read More
Organisms grown in Fluid Thioglycollate Media w/out resazurin dye is a reducing media that uses sodium thioglycollate to chemically combine with dissolved oxygen to deplete the oxygen in the media.
