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 100¦Ìg ml-1 (70.54%) in S1-I and the control was recorded at 84.6%. http://pubs.sciepub.com/aees/9/1/10/aees-9-1-10.pdf Multi-stress S platensis Scavenging Activity
