Abstract

The present invention relates to microalgae having high efficiency and ability to remove carbon dioxide, and the use thereof. More specifically, the invention relates to Scenedesmus producto-capitatus microalgae having high carbon dioxide fixation rate and the use thereof. The microalgae of the invention have a high carbon dioxide fixation rate and excellent resistance even to high concentrations of carbon dioxide, sulfur oxide (SOx) and nitric oxide (NOx) and are rich in biomass, and thus can be advantageously used in formulations for removing carbon dioxide.

Claims

1. Scenedesmus producto-capitatus microalgae, which have a high carbon dioxide fixation rate and are identified by accession number KCTC11336BP.

2. Scenedesmus producto-capitatus microalgae of claim 1, wherein the microalgae have a resistance to sulfur oxide (SOx) or nitric oxide (NOx).

3. A formulation for removing carbon dioxide, which contains at least one selected from the group consisting of the microalgae claim 1, a culture of the microalgae and a lysate of the microalgae.

4. The formulation of claim 3, wherein the formulation comprises foods, cosmetics or feeds.

5. A method of removing carbon dioxide using at least one selected from the group consisting of the microalgae of claim 1, a culture of the microalgae and a lysate of the microalgae.

6. The method of claim 5, wherein the method comprises introducing the culture and the microalgae into a microalgal reactor and supplying carbon dioxide to the reactor while irradiating light.
