Abstract: In this present study antimicrobial activity of Myriostachya wigtiana (Poaceae), 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 highest activity showed against B. bicolor- MTCC 2105 (18 mm) with MIC (75 mg/ml) followed by C. lunata (15 mm), E. carotovora (15 mm) and P. marginales (16 mm), where as lowest activity with A.strictum (9 mm) with 100 mg/ml and no activity were found against C. herbarum and M. phaseolina with all extract concentrations (100, 300 and 500 mg/ml). This study, has to some extent, validated the medicinal potential of the mangrove plants.
