Description
Ulva fasciata is a common sea weed and known for various medicinal properties. The aim of
the present study was to screen the antimicrobial activity of Ulva fasciata against clinical
isolates of bacteria. The aqueous extract of the U. fasciata was studied for its antagonistic
activity against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and
Klebsiella pneumoniae. In vitro antimicrobial activity was performed by Agar well diffusion
method in Muller Hinton agar. The extract showed significant effect on the tested organisms.
The extract showed maximum zone of inhibition against E. coli (15.6±1.3) whereas, lowest
against K. pneumoniae (11.2±1.02). Minimum Inhibitory Concentration (MIC) of aqueous
extract was measured by modified agar well diffusion method. The MIC value of crude
extract was 16.2, 5.4, 7.1 and 15 mg/ml against E. coli, K. pneumoniae, P. aeruginosa and S.
aureus respectively.
