  • Publication number: 20240066110
    Abstract: The present invention relates to an immunogenic composition including multivalent pneumococcal polysaccharide-protein conjugates. Each conjugate includes capsular polysaccharides of different pneumococcus serotypes conjugated to a carrier protein. More concretely, the present invention is a multivalent immunogenic composition including polysaccharide-protein conjugates. Each of the polysaccharide-protein conjugates includes Streptococcus pneumoniae-derived capsular polysaccharides of different serotypes conjugated to a carrier protein. The capsular polysaccharides include a) capsular polysaccharides of one or more serotypes selected from the group consisting of serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F, and b) capsular polysaccharides of one or more serotypes selected from the group consisting of serotypes 10A, 11A, 12F, 15B, 22F, 23A, and 35B.

  • Patent number: 9719097
    Abstract: The present disclosure discloses a vector that can be used for both cyanobacteria and E. coli, 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.

  • Patent number: 9688976
    Abstract: Disclosed herein are a transformed Synechococcus elongatus strain 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 transformed Synechococcus elongatus strain of the present disclosure can produce acetone with high selectivity using carbon dioxide as a carbon source. The present disclosure is economical because the Synechococcus elongatus strain 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.
