ESTIMATION OF SOME ACTIVE COMPOUNDS IN LOCAL ISOLATE OF SPIRULINA LAXA G.M. SMITH

Abstract

This study includes isolation, purification and Identification of a local isolate of the Cyanobacteria Spirulina laxa G.M. Smith from sulfur water in Al-Anbar Governorate, west of Iraq. Using the dilution method, the studied sample was isolated and cultured in BG11medium and used antibiotics to obtained Axenic culture. The Biomass was Dried under 45 Co for 24 hrs. to get Dry powder. The results of analysis of some compounds in S. laxa G.M. Smith showed that the biomass contained (59.2%) protein, and (14.8%) carbohydrate and the amount of chlorophyll A was (410.6 mg / 100 mg). The total amount of phenols and flavonoids was (94.5 mg) and (56.9mg), respectively. The result revealed S. laxa G.M. Smith has a high amount of antioxidants.
