BESC Announces Microbe That Significantly Improves Isobutanol Yields

On August 14, 2015, the Department of Energy's (DOE) BioEnergy Science Center (BESC) announced the creation of a microbe that increases isobutanol yields by a factor of ten. The study, published in Metabolic Engineering, expanded upon a 2011 study where researchers were able to engineer genetically a microbe to produce isobutanol directly from cellulose. The new study used a higher yielding microbe with similar engineered traits, resulting in consolidated bioprocessing efficiency. This...

BP And DuPont Isobutanol Plant Groundbreaking

Butamax™ Advanced Biofuels LLC, a joint venture between BP PLC and DuPont, announced that it has broken ground on a plant to produce isobutanol, a renewable fuel that EPA has determined can qualify for credit under the federal RFS. Butamax is working to retrofit Highwater Ethanol LLC, an existing ethanol plant located in Lamberton, Minnesota. The announcement is significant because Butamax has been in ongoing litigation with the other U.S. isobutanol producer, Gevo. Also, isobutanol...
