Study of Antimicrobial Activity of Tissue Extracts from Bivalve Geloina proxima (Prime, 1864) from Dapoli Coast of Ratnagiri District Maharashtra (India)

Mangrove bivalve Geloina proxima of family Corbiculidae is one of the most dominant indigenous giant mangrove bivalve of Dapoli coast. It has great commercial value and biodiversity importance. Despite their economic importance and food potential, this bivalve has received very little attention. Hence, its potential antibacterial activity against human pathogenic bacteria is assayed. The foot and gills tissue extracts were prepared in 06 different solvents and assayed for antibacterial activity by using disc diffusion method against 08 different human pathogenic bacteria. Among the extracts, the Butanol, Ethanol, Methanol, Acetone and Hexane crude extracts showed potential antibacterial activity for most of the pathogenic bacteria. The foot extracts in Butanol and gill extracts in Ethanol have showed higher activity with maximum inhibition zone
