subjectAbstract

Acetone, methanol, chloroform, diethyl ether, ethyl acetate, hexane and aqueous extract of green seaweeds Chetomorpha linum was screened for antibacterial activity by well diffusion methods against five fish bacterial pathogens Pseudomonas aeruginosa, Vibrio alginolyticus, Aeromonas hydrophila, Vibrio parahaemolyticus, Enterobacter aerogenes. In our observations the highest inhibition zone was recorded in methanol extract (28 mm) and ethyl acetate extract (20 mm) of C. linum against Pseudomonas aeruginosa. No activity was recorded in chloroform, distilled water and negative control against all tested pathogens. Results from this survey demonstrate that antimicrobial activities are prevalent among extracts from marine algae, suggesting that antimicrobial chemical defenses are widespread among marine plants. The present study provides enough data to show the potential of algae extract for development o anti-pathogenic agents for use in aquaculture.
