Engineering Bacillus subtilis for Isobutanol Production by Heterologous Ehrlich Pathway Construction and the Biosynthetic 2-ketoisovalerate Precursor Pathway Overexpression
In this research article, Bacillus subtilis was engineered as the cell factory for isobutanol production due to its high tolerance to isobutanol. Follow this link to learn more: http://www.springerlink.com/content/aq3588xwr152265x/
High-flux Isobutanol Production using Engineered Escherichia coli: A Bioreactor Study with in situ Product Removal
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.

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.
