With the licensing to Enchi Corporation of a microbe custom-designed to produce ethanol efficiently, Oak Ridge National Laboratory (ORNL) and the BioEnergy Science Center (BESC) mark the culmination of 10 years’ research into ways to improve biofuels production. Enchi ha...

Gerald Tuskan will serve as Chief Executive Officer of the new ORNL-led Center for Bioenergy Innovation, one of four DOE bioenergy research centers.

The Department of Energy has announced funding for new research centers to accelerate the development of specialty plants and processes for a new generation of biofuels and bioproducts. The Center for Bioenergy Innovation (CBI), led by Oak Ridge National Laboratory...

ORNL bioscience researcher Jerry Tuskan had an early interest in plant genetics.

It’s been 10 years since the Department of Energy first established a BioEnergy Science Center (BESC) at Oak Ridge National Laboratory, and researcher Gerald “Jerry” Tuskan has used that time and the lab’s and center’s resources and tools to make good on his college dreams of usi...
