ALTERNATIVE BUTANOL PRODUCTION PROCESS IN A MICROBIAL CELL

摘要

The present invention relates to a microbial cell comprising genes encoding enzymes that catalyse the following reactions a) pyruvate to acetolactate, b) acetolactate to 2,3-dihydroxyisovalerate, c) 2,3-dihydroxyisovalerate to 2-ketoisovalerate, d) 2- ketoisovalerate to isobutyryl-CoA, e) isobutyryl-CoA to butyryl-CoA, f) butyryl-CoA to butyraldehyde, and g) butyraldehyde to butanol, wherein the cell produces butanol. The invention further relates to a process for the production of butanol wherein the microbial cell according to the present invention is used.
