Abstract
In this study Gracilaria edilis, sargassam and Padina gymnospora from Raameshwaram sea, Tamil Nadu were collected, identified and tested against various pathogenic bacteria. In Antibacterial assay Acetone shows the maximum number of activity against the Salmonella typi (32mm) length of inhibtions occurred andAcetone shows the minimum activity against Klebsiella pneumonia (18mm) of the inhibition level. Under the Antifungal assay Acetone shows the maximum activity against the penicillium.sp, (10mm) of the inhibition. Acetone shows the moderate activity against the Aspergillus niger (5mm) of inhibition and the minimumactivity in candida sp,. (8mm) of inhibition zone level.

Summary
Seaweeds are a marine algae is a potential source of bioactive substances. Seaweeds have been traditionally used in human and animal nutrition. Streptococci, Lactobacilli,Staphylococci, Cornybacteria, and with a great number of anaerobes, especially Seaweeds are considered as a source of bioactive compounds with cytostatic, antiviral, anti helminthic, antifungal and antibacterial activities. They have been used to treat some diseases like cancer, arthritis etc. Seaweeds are the renewable living sources which are used as food, feed and fertilizer in many parts of the world. They have been screened extensively to isolate life saving drugs or biologically active substances all over the world
