Antifungal Activity of Certain Seaweeds from Puthumadam Coast

Abstract

Antifungal activity of seaweed extracts in Petroleum ether, benzene, chloroform, Methanol, ethyl acetate, and water extracts was made.Antifungalactivity of five species of Seaweed was explored. This activity was evaluated by Disc diffusion method. The minimum inhibition zone concentrations were also determined for two fungal pathogens namely Pythiumaphanidermatam, Colletotrichumcapsici. All the extracts used in this study were exhibited antifungal activity. The lowest inhibition zone effect was noticed for Sargassumwightii, followed by sargassumillicifolium, andTurbinariaconoides(Brown seaweeds) and the highest inhibiting of zone effect was noted forUlvafasciata (Green seaweed), Gracilariacorticata(red seaweed),Sargassumilicifolium, andTubinariaconoideswas also not growth against Colletotrichumcapsici were completely not inhibition zone in ethyl acetate extract. These results suggest that seaweeds collected fromputhumadam coast in Tamil nadu Gulf of mannarregion is potential significances capacity which makes them interesting for screening of natural product
