ANTIBACTERIAL AND ANTIOXIDANT POTENTIAL OF ULVA AND ECTOCARPUS

Megha Mole, Anjali Sabale

Abstract :

 Crude extracts of Ulva lactuca Lin. and Ectocarpus siliculosus C. Agardh prepared in different organic solvent were screened to determine their antibacterial and antioxidant potentials. DPPH radical scavenging  activity, FIC ability, reducing power, H2O2 scavenging activity and TAC were determine in the three organic solvents  viz. methanol, ethanol and water. All ethanolic seaweed extracts inhibited the growth of gram negative (Escherichia coli  and Proteus vulgaris) and gram positive (Bacillus subtilis, Salmonella typhi and Staphylococcus aureus) bacterial strains.  Hexane extract of E. siliculosus exhibited the maximum antibacterial activity against E. coli and S. aureus (25 & 23mm  inhibition zone respectively). The methanolic extracts of U. lactuca had an appreciable antioxidant property (FIC, H2O2  scavenging activity and TAC) while aqueous extract of E. siliculosus had the maximum reducing power and DPPH scavenging activity.
