CORYNEFORM BACTERIUM TRANSFORMANT, AND PROCESS FOR PRODUCING ISOBUTANOL USING SAME

摘要

A Corynebacterium glutamicum transformant having the capability of producing isobutanol and the following genes (1) to (5):
(1) a gene which encodes an enzyme having acetohydroxy acid synthase activity;
(2) a gene which encodes an enzyme having acetohydroxy acid isomeroreductase activity;
(3) a gene which encodes an enzyme having dihydroxy acid dehydratase activity;
(4) a gene which encodes an enzyme having 2-keto acid decarboxylase activity; and
(5) a gene which encodes an enzyme having alcohol dehydrogenase activity,
at least one of the genes being endogenous, and at least one of the genes being exogenous, efficiently produces isobutanol.
