Abstract
The present invention relates to novel microalgae with high productivity of loliolide, in which the Scenedesmus sp. HS4 of the present invention can be used as a biological resource to produce loliolide due to its high biomass productivity and high loliolide content, and can be used as a pharmaceutical composition or cosmetic composition which requires loliolide derived from Scenedesmus sp. HS4.
Claims3
A freeze-dried strain of Scenedesmus sp. HS4 deposited under Accession No. KCTC 13784BP, wherein the strain is prepared by culturing Scenedesmus sp. JD052 for one month under conditions where an initial light dose is 50 μmol:m−2:s−1 and an initial concentration of glucose is at 0 g/L;
- culturing for one month under conditions where a light dose is 30 μmol-m−2:s−1 and a concentration of glucose is 0.1 g/L;
- culturing for one month under conditions where a light dose is 15 μmol-m−2:s−1 and a concentration of glucose is 1 g/L;
- culturing for one month under conditions where a light dose is 5 μmol:-m−2-s−1 and a concentration of glucose is 5 g/L;
- and finally culturing for one month under conditions where a light dose is 0 μmol:m−2:s−1 and a concentration of glucose is 10 g/L, and
- wherein the freeze-dried strain is in the form of an emulsion, a tablet, a capsule, or a gel.
A composition comprising a freeze-dried strain of Scenedesmus sp. HS4 deposited under Accession No. KCTC 13784BP and an additive, wherein the strain is prepared by culturing Scenedesmus sp. JD052 for one month under conditions where an initial light dose is 50 μmol-m−2:s−1 and an initial concentration of glucose is at 0 g/L;
- culturing for one month under conditions where a light dose is 30 μmol-m−2:s−1 and a concentration of glucose is 0.1 g/L;
- culturing for one month under conditions where a light dose is 15 μmol-m−2:s−1 and a concentration of glucose is 1 g/L;
- culturing for one month under conditions where a light dose is 5 μmol-m−2:s−1 and a concentration of glucose is 5 g/L;
- and finally culturing for one month under conditions where a light dose is 0 μmol:m−2-s−1 and a concentration of glucose is 10 g/L, and
- wherein the composition is in the form of an emulsion, a tablet, a capsule, or a gel.
