Patent
A novel microalgal strain whose lipid production has been enhanced compared to the wild type. The lipid content produced by the microalgae is particularly rich in neutral lipids. The use of the microalgal strain and the lipids are also described.
1. A strain of the microalgae Isochrysis affinis galbana Tahitian clone, deposited within the Culture Collection of Algae and Protozoa (CCAP) under accession number CCAP 927/17, wherein said microalgae has a lipid content increased by at least 75% compared to the wild type Isochrysis affinis galbana clone Tahiti (T-iso) CCAP accession no. 927/14.
2. The microalgal strain of claim 1 , wherein said lipid content comprises at least 70% of neutral lipids.
3. The microalgal strain of claim 1 , wherein said lipid content comprises at least 18% of polyunsaturated fatty acids.
4. The microalgal strain of claim 1 , wherein said microalgae has a growth rate similar to the growth rate of the wild type Isochrysis affinis galbana clone Tahiti (T-iso) CCAP 927/14.
5. A method of producing a lipid extract, comprising:
a. Culturing the microalgal strain according to claim 1 ; and
b. Harvesting the lipid content from said microalgal strain to obtain the lipid extract.
6. A method of producing an aquatic species under aquacultural conditions, comprising feeding to the aquatic species a nutritionally effective amount of the microalgal strain according to claim 1 .
7. The microalgal strain of claim 1 , wherein said microalgae has a lipid content increased by at least 100% compared to the wild type Isochrysis affinis galbana.
8. The microalgal strain of claim 1 , wherein said lipid content comprises at least 80% of neutral lipids.
9. The microalgal strain of claim 1 , wherein said lipid content comprises at least 20% of polyunsaturated fatty acids.
