## Abstract

The present invention relates to a novel Spirulina strain having a linear shape, which Spirulina strain can be used to achieve a harvest of Spirulina strain with high yield.

## Claims

### Claim 1

An Arthrospira platensis NCB002 strain having a linear shape and deposited with accession number KCTC 13731BP.

### Claim 2 (depends on 1)

The strain according to claim 1, wherein the strain has a linear shape with a length of 0.5 to 3 cm.

### Claim 3 (depends on 1)

The strain according to claim 1, wherein the strain is able to survive in a medium containing NH4Cl in an amount of 0.4 g/L or less.

### Claim 4 (depends on 1)
