Abstract
Official abstract text for this publication.
According to the present invention, a microorganism belonging to the genus Aurantiochytrium having an 18S rRNA gene consisting of the base sequence represented by any of SEQ ID NOS: 1 to 5; Aurantiochytrium sp. OH4 strain; a microorganism which is a mutant obtained from the above-mentioned microorganism as a parent strain and has a higher ability to produce DHA than the parent strain; or Aurantiochytrium sp. LTR23 strain is provided. Also, a method for producing a DHA-containing composition, DHA and DHA alkyl ester by a fermentation process using the above-mentioned microorganisms is provided.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a docosahexaenoic acid-containing composition, comprising culturing Aurantiochytrium sp. OH4 strain (Accession Number: FERM BP-11524) in a medium, allowing the docosahexaenoic acid-containing composition to be produced and accumulated in a culture, and collecting the docosahexaenoic acid-containing composition from the culture. 2. A method for producing docosahexaenoic acid comprising separating and collecting docosahexaenoic acid from the docosahexaenoic acid-containing composition collected according to claim 1 . 3. A method for producing docosahexaenoic acid alkyl ester comprising separating and collecting docosahexaenoic acid alkyl ester from the docosahexaenoic acid-containing composition collected according to claim 1 . 4. A method for producing docosahexaenoic acid alkyl ester according to claim 3 , wherein the docosahexaenoic acid alkyl ester is docosahexaenoic acid methyl ester. 5. A method for producing docosahexaenoic acid alkyl ester according to claim 3 , wherein the docosahexaenoic acid alkyl ester is docosahexaenoic acid ethyl ester.
