Abstract: Butanol-producing Clostridia as butanol fermentation strains have been studied frequently in recent years. As a new renewable energy sources,butanol has obviously more advantages than ethanol. Therefore,it is of great significance to study gene modification of butanol-producing Clostridia. In this review,from three aspects of key genes,glycolytic pathway,and butanol tolerance,we introduced the latest research progress on gene modification of butanol-producing Clostridia. Meanwhile,we discussed the issues in the current research,and put forward suggestions on how to improve the butanol yield,aiming at providing some new ideas for the researchers.

Key words: butanol-producing Clostridia, ABE fermentation, EMP, gene overexpress, gene inactivation, butanol tolerance
