Amino acid composition and protein efficiency ratio (PER) ofSpirulina platensis

  • Published:
Proceedings / Indian Academy of Sciences

Abstract

The amino acid composition of the blue-green algaSpirulina platensis was determined and compared with other algal, vegetable and animal protein sources. The alga with 58·5% protein is rich in lysine and tryptophan, but deficient in sulphur containing amino acids. Of the three species ofSpirulina, S. platensis has a higher content of sulphur containing amino acids. The PER of this alga is much higher than that of other algae likeChlorella andScenedesmus.
