Abstract:
Hemocyanin is an extracellular copper-containing protein present in the hemolymph of both mollusks and
arthropods. The traditionally recognized function of hemocyanin is for oxygen transport. Lately, it was
demonstrated that hemocyanin is a multifunctional protein, especially participating in multiple roles of immune
defense. For better understanding its actions in immune defense, the hemolytic activity of hemocyanin from
gaint Africa and the antimicrobial potentials were investigated in this study. In order to study the antibacterial
activity of heamocyann from Gaint Africa snail were tested against six bacteria. Among the six bacterial, 95%
of the bacterial showed susceptibility against e.colil at the concentrations conducted in this experiment. After
studying the MIC 95% 0f the bacteria were destroyed at 100mg/mi concentration. Result shows that in the
presence of microbes heamocyanin become activity to form a very potent antimicrobial agent.
