| Abstract: | Macroalga, Ulva fasciata was collected, extracts prepared, fractionated using different solvent systems and screened for their antibiotic sensitivity against pathogenic bacterial strains. Methanol extract of U. fasciata inhibited 66% of Gram +ve bacteria, whereas the activity was less towards aqueous extract. Inhibitory potential of methanol extract of U. fasciata was high with 78.5 mm2 towards Gram +ve strain of Staphylococcus aureus at 20oC than at 30oC compared to the commercial antibiotics. Among the active fractions, successful inhibition was noted in FD2 - CH2Cl2: MeOH (1:1), M4 - Methanol - Acn and MD1-MeOH - dcm fractions. The FD2 (chloroform and methanol combinations) fraction against MOF 1 (shrimp, Penaeus monodon isolate) and MOF 2 (Clown fish isolate) isolates were found to be most active with highest inhibitory zone of ≥143.06 mm2. |
