Antimicrobial Activity from the Gill Extraction of Perna viridis (Linnaeus, 1758)

Molluscs are highly delicious seafood and they are also very good source for biomedically imported products. Among the molluscs some have pronounced pharmacological activities or other properties which are useful in the biomedical area. In the present study antimicrobial activity of gill extraction of Perna viridis was investigated. In antibacterial activity the maximum zone of inhibition (19 mm) was observed against Staphylococcus aureus and minimum activity (11 mm) was observed in Salmonella paratyphi. In antifungal activity maximum zone of inhibition was observed in Aspergillus flavus (13mm) and minimum zone of inhibition was recorded in Mucor sp (11mm). The gill extraction samples showed antimicrobial activity was subjected to SDS-PAGE to estimate the molecular weight of proteins present after electrophoresis only one clear band were detected in the gel which represented proteins of molecular weight 9.7 kDa. In the present study indicated that the gill extraction of P.viridis may potential source for antibiotics.
