Abstract:

The Seaweed, Gracilaria edulis, collected from Mandapam coast, was studied for Biochemical characterization of protein. Aqueous and methanol extracts yielded a total amount of 6.3 and 5.7 from 500 g of seaweed respectively. Crude protein extracts from the seaweed was 1.9 mg/mL in aqueous and 2.7 mg/mL in methanol extract respectively. The partial purification of protein is done by using DEAE cellulose. The aqueous and methanol extracts showed highest antioxidant activity in DPPH (95 and 82%). On SDS-PAGE the crude protein yielded four well defined bands at 31.4, 69.5, 92.7 kDa in both the extracts. The Fatty acid profile showed that myristic acid was dominant in chloroform extract and palmitic acid was dominant in aqueous extract.
