From the summary

--

The disclosure provides a recombinant microorganism that produces an alcohol selected from the group consisting of: (a) 1-propanol, (b) isobutanol and having a yield of about 0.12 to about 0.41 grams of isobutanol per gram of glucose; (c) 1-butanol, (d) 2-methyl 1-butanol, (e) 3-methyl 1-butanol, and (f) 2-phenylethanol, wherein the alcohol is produced from a metabolite comprising 2-keto acid. In one embodiment, the organism produced less than about 240 mg/L of ethanol at about 112 hrs of culture. In another embodiment the alcohol production profile of the microorganism is substantially identical to the alcohol production profile of the microorganism designated SA237 or CRS-BuOH23, when cultured under similar conditions
