Researchers identify genes in yeast that increase ethanol tolerance; may boost cellulosic ethanol production

Green Car Congress

Our hope is that this research will take us closer to the goal of producing cheap, efficient, and environmentally friendly cellulosic ethanol. Assistant Professor of Genetics, University of Wisconsin-Madison. At the same time, we’ve learned a lot about how cells respond to alcohol stress. —Audrey P. Gasch, Ph.D.,

Electrostatic Motors Reach the Macro Scale

Cars That Think

For decades, however, engineers have been tantalized by the virtues of motors based on an entirely different principle: electrostatics. And, perhaps even better, they would use only cheap, plentiful materials, rather than the rare-earth elements, special steel alloys, and copious quantities of copper found in conventional motors.

New yeast engineered by BESC, Mascoma could accelerate production of cellulosic ethanol

Green Car Congress

Although cellulosic biomass such as corn stover, wheat straw and bagasse (the fibrous remains after sugar is extracted from sugarcane or sorghum) is abundant and cheap, because of recalcitrance—a plant’s resistance to releasing sugars for conversion to alcohol—it is much more difficult to utilize than corn.

BESC team engineers microbe for direct production of isobutanol from cellulose

Green Car Congress

James Liao of UCLA, has for the first time produced isobutanol—an alcohol that is more attractive for transportation use than ethanol—directly from cellulose using a genetically engineered microbe. Plus, it may be possible to use isobutanol directly in current engines without modification. Earlier post.) —James Liao.
