BioEnergy Science Center (BESC) at the Oak Ridge National Laboratory researchers have crashed through another barrier to commercially viable biofuels with the engineering of a microbe that improves isobutanol yields by a factor of 10. The group’s work builds on results from 2011 in which researchers reported on the first genetically engineered microbe to produce […]

A University of Michigan research team has joined the forces of a fungus and E. coli bacteria to turn tough waste plant material into isobutanol, a biofuel that closely matches gasoline’s properties in a combined species process.  The research team members said the principle also could be used to produce other valuable chemicals such as […]

Renewable alternatives to gasoline like heavy alcohols such as isobutanol are promising candidates that are getting closer to your gas tank. The heavier alcohols have more carbon atoms than ethanol with two and methanol with just one.  They contain more energy than ethanol, but they are also more compatible with the existing gasoline-based infrastructure.  The […]

Oak Ridge National Laboratory has announced two of its scientists, Yongchao Li and Yunfeng Yang of ORNL collaborating with a team led by James Liao of the University of California at Los Angeles has for the first time produced isobutanol directly from cellulose.  This achievement has been for years a prime national goal, as it […]
