Method for preparing butanol through butyryl-coa as an intermediate using yeast

摘要

Disclosed herein are a method for producing butanol in yeast having the ability to biosynthesize butanol using butyryl-CoA as an intermediate, the method comprises producing butyryl-CoA in yeast having a CoAT (acetyl-CoA:butyryl-CoA CoA-transferase)-encoding gene introduced thereinto, through various pathways, and then converting the produced butyryl-CoA to butanol.
