Abstract—In this investigation of Iophon Laevistylus, collected from Faro Island in Persian Gulf, was extracted of polar and nonpolar contents using the method of Bligh & Dyer. Methanolic and diethyletter were used as extraction solvents, after removal of the solvents, the GC/MS spectra of the fraction were obtained. Identification of constituents was made by comparison of their masss pectra and retention indices (RI) with those given in the literature and authenic samples. 19 components respecting 95% were identified carbohydrate. In vitro antibacterial screening, against selected clinical isolates of bacteria was conducted in this study. Methanolic and diethy letter extracts demonstrated activity against Escherichia coli and Bacillus subtilis microbes tested. MIC and MBC were determined using Bacterial Broth Dilution Methods. The extracts showing good antimicrobial activity are undergoing further analysis to identify the active constituents.

Index Terms—Iophon Laevistylus, MIC (minimum inhibitory concentration), MBC(minimum bacterial concentrate), Antibacterial activity and Persian Gulf.
