The present disclosure discloses a vector that can be used for both cyanobacteria and, which contains, sequentially, a pUC replication origin as a replication origin; a spectinomycin-resistant gene as a selection marker; and a promoter selected from a group consisting of a trc promoter, a tetA promoter or a modified tetA promoter, a BAD promoter and a cbbL promoter. An industrially useful substance may be produced effectively using a host cell transformed with the vector. Also, the vector may be used to insert a variety of target genes through simple combination and, as a result, various vectors can be prepared effectively.

Expression vector for cyanobacteria

Disclosed herein are a transformedstrain having improved capability of producing acetone and a method for producing acetone and a method for removing carbon dioxide using the same. In an aspect, the transformedstrain of the present disclosure can produce acetone with high selectivity using carbon dioxide as a carbon source. The present disclosure is economical because thestrain can economically produce high value-added acetone using carbon dioxide existing in the atmosphere as a carbon source without requiring an additional catalytic reaction. Also, the present disclosure is environment-friendly because carbon dioxide in the atmosphere can be removed or reduced using the microorganism.
