제목 Development of Shuttle Vectors for Succinic Acid Producing Bacteria
초록 In order to obtain improved succinic acid producing bacteria by metabolic engineering, shuttle vectors for Mannheimia succiniciproducens, Actinobacillus succinogenes and Escherichia coli were constructed. The pMVD, pME and pMEx vectors were manipulated fusing a Mannheimia varigena plasmid pMVSCS1 with an E. coli expression vector pKK223-3. The performance of the vectors was evaluated by cloning a fumC gene into M. succiniciproducens and A. succinogenes. The stability of the vectors was also tested by using ampicillin as a selection marker. The quantitative real-time PCR method was used to analyze the plasmid copy number. The increased level of the activity and expression of the fumarase encoded by the fumC gene in the recombinant M. succiniciproducens and A. succinogenes suggests that the vectors constructed in this work can be used for engineering them as a succinic acid producer.
