Promising approaches to produce higher alcohols, e.g., isobutanol, using Escherichia coli have been developed with successful results. This research translates the isobutanol process from shake flasks to a 1-L bioreactor in order to characterize three E. coli strains.

Carbon Emission Reduction Impacts from Alternative Biofuels
Using life-cycle analysis to evaluate alternative uses of wood including both products and fuels reveals a hierarchy of carbon and energy impacts characterized by their efficiency in reducing carbon emissions and/or in displacing fossil energy imports.

Metabolic Engineering of Clostridium cellulolyticum for Production of Isobutanol from Cellulose
Producing biofuels directly from cellulose, known as consolidated bioprocessing, is believed to reduce costs substantially compared to a process in which cellulose degradation and fermentation to fuel are accomplished in separate steps. This research presents a metabolic engineering example for the development of a Clostridium cellulolyticum strain for isobutanol synthesis directly from cellulose.

Transgenic Microbe Converts Cellulose to Isobutanol Fuel
In the quest for inexpensive biofuels, U.S. scientists have created a genetically engineered microbe and used it to convert plant matter directly into isobutanol. Follow this link to learn more: http://www.ens-newswire.com/ens/mar2011/2011-03-08-091.html
Engineering Corynebacterium glutamicum for isobutanol production

Second-Generation Biofuel: Isobutanol Producing Biocatalyst
With support from EPA’s Small Business Innovation Research (SBIR) Program, Gevo launched a project to identify rate-limiting steps in the isobutanol pathway in yeast. This effort resulted in the development of genetic and biochemical assays to characterize each of the enzymes involved in the production of isobutanol in yeast.
