As we become more aware that our oceans are not boundless and need to be cared for, more and more studies are being done to see what nature's underwater pharmacy contains. Here is the first I have thought to record, please add discoveries as you find them. MOLECULAR CHARACTERIZATION AND ANTIMICROBIAL ACTIVITY OF OCTOPUS AEGINA AND OCTOPUS DOLFUSII IN GULF OF MANNAR COAST S Monolisha, AE Mani, J Patterson, JKP Edward August 2013 pdf available in the link Abstract 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 Vibro parahaemolyticus and the protein content was 107.16 ug/L and 136.20 ug/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 species. Conclusively, the factors analyzed proved that the sample species play an important role in chemicalj defensive mechanism against pathogens causing disease in human and fishes. This study paves a way for further pharmaceutical research against pathogenic bacterial strains producing valuable drugs.
