ANTIFUNGAL ACTIVITY OF ACANTHOPHORA SPICIFERA, PADINA TETRASTOMATICA AND CAULERPA SCALPELLIFORMIS AGAINST SOME FUNGAL PATHOGENS IN CRUDE AND FRACTIONATED FORM
*Dr. D. Radhika and R. Priya
ABSTRACT
One representative from each group of seaweeds namely
Acanthophora spicifera from Rhodophyceae, Padina tetrastomatica
from Phaeophyceae and Caulerpa scalpelliformis from Chlorophyceae
was chosen. Crude and fractions of the seaweeds were taken using four
solvents namely water, ethanol, acetone and methanol by soxhlet
extraction. They were then compared for their antifungal activity by
disc diffusion technique against five fungal strains, namely Aspergillus
terrus, A. fumigatus, Gibberline sp., Alternaria sp. and Ganoderma sp.
A. fumigatus was the highest inhibited fungal species followed by
Alternaria sp. and A. terrus. Ganoderma sp. showed the least activity
against all the pathogens tested.
Keywords: Seaweeds, Acanthophora, Antifungal, Aspergillus, Alternaria, Disc Diffusion.
