The present disclosure provides a Schizochytrium sp. Strain and its use thereof.

First claim

Opening claim text (preview).

1 . Schizochytrium sp. strain that is a microalgae deposited under accession number KCTC15201BP. 2 . The strain according to claim 1 , wherein the strain has the 18s rRNA nucleotide sequence of SEQ ID NO: 1. 3 - 4 . (canceled) 5 . The strain according to claim 1 , wherein the genomic DNA of the strain comprises a nucleotide sequence in which 36 nucleotides are deleted from the nucleotide sequence of SEQ ID NO: 4 of Schizochytrium sp. CD01-1821 strain, which is the parent strain. 6 . The strain according to claim 5 , wherein the nucleotide sequence in which 36 nucleotides are deleted from the nucleotide sequence of SEQ ID NO: 4 consists of SEQ ID NO: 5. 7 . (canceled) 8 . A microbial product for producing DHA (Docosahexaenoic acid, 22:6) comprising the strain of claim 1 or a culture solution thereof as an active ingredient. 9 . Biomass derived from a Schizochytrium sp. strain, comprising the strain of claim 1 , a culture solution of the strain, a dry matter of the culture solution, or a lysate of the dry matter. 10 . A feed composition, comprising the biomass derived from a Schizochytrium sp. strain of claim 9 , or a concentrate, dry matter or extract of the biomass. 11 . A food composition, comprising the biomass derived from a Schizochytrium sp. strain of claim 9 , or a concentrate, dry matter or extract of the biomass. 12 . A method for producing biomass derived from a Schizochytrium sp. strain, comprising; culturing the strain of claim 1 ; and recovering biomass containing DHA (Docosahexaenoic acid, 22:6) from the strain, a culture solution thereof, or a dry matter or lysate of the culture solution. 13 . A method for producing bio-oil derived from a Schizochytrium sp. strain, comprising; culturing the strain of claim 1 ; and recovering bio-oil containing DHA (Docosahexaenoic acid, 22:6) from the strain, a culture solution thereof, or a dry matter or lysate of the culture solution.
