Molecular Characterization And Antimicrobial Activity Of Octopus Aegina And Octopus Dolfusii In Gulf Of Mannar Coast

Antibacterial activity and protein content was studied in two species of octopus belonging to the family Octopoda. The highest zone of inhibition of about 34mm and 28mm were obtained against Vibrio parahaemolyticus and the protein content was 107.16 mu g/L and 136.20 mu g/L in Octopus dolfusii and Octopus aegina, respectively. SDS profile revealed bands of molecular weight of about 32.83 KDa to 72.36 KDa for both the species. Conclusively, the factors analyzed prove that the sample species play an important roles in chemical defensive mechanism against pathogens causing diseases in human and fishes. This study paves a way for further pharmaceutical research against pathogenic bacterial strains producing valuable drugs.
