摘要

Method for converting acetolactate in dihidroxijsovalerato, method for producing jsobutanol,Recombinant host cell and method to identify and isolate a genetic construct, the present invention provides methods for the fermentative production of butanol by fermentation growth.A recombinant microorganism expressing an enzyme CETOL acid redutoisomerase highly active, in addition to other enzymes necessary for the conversion of glucose to isobutanol.
