ABSTRACT: In this present study antimicrobial activity of Bruguiera cylindrica (Rhizophoraceae), the plant parts of were collected from coringa forest near Kakinada, Godavari-krishna delta area were dried and extracted successively with hexane, chloroform and methanol using the soxhlet extraction apparatus. The antimicrobial activities of the organic solvent extracts on the various test microorganisms, including bacteria and fungi investigated using agar well diffusion technique. Methanol extracts exhibited promising antimicrobial activity than chloroform and hexane extracts. Among all tested microorganisms Pseudomonas syringae (26 mm) and Xanthomonas campestris (22 mm) showed highest growth inhibition where as no activity were found with Pseudomaonas marginales, Cladosporium herbarum and Macrophomina phaseolina with concentration (100 mg/ml) . This study, has to some extent, validated the medicinal potential of the mangrove plants.
