  • Patent number: 10155964
    Abstract: The present specification discloses a transformed Synechococcus elongatus strain which may directly produce squalene from carbon dioxide, and a method for producing squalene and a method for removing carbon dioxide, using the same. In an aspect, the strain may produce squalene using carbon dioxide as a carbon source. The Synechococcus elongatus strain is economically efficient because a high-value added squalene is produced using light and carbon dioxide present in the atmosphere as a carbon source, and the method for producing squalene is eco-friendly because the strain may be utilized to remove or reduce carbon dioxide in the atmosphere by using microorganisms. The strain of the present disclosure may produce only squalene, which is a desired target material with high purity, and has an advantage in that squalene may be continuously mass-produced.
