Extraction and Purification of Phycocyanin and Their Radical- Scavenging Activity from Multi - Stress Spirulina Isolated from Marine Water

Abstract

The S. platensis were isolated from the marine water were mass mass cultivated and extracted they were partially purified of phycocyanin pigment by SDS -PAGE . In the present study the extracts were partially purified and with some organic impurities and subjected to 7.5 % of SDS-PAGE gel the strain S-I resembles the almost the molecular weight around 110 kda when compared to standard reference strain under multi stress condition. Similarly in the present study, reported that the higher amount of scavenging activity was recorded at 100μg ml-1 (70.54%) in S1-I and the control was recorded at 84.6%.
