On the other hand, L. pavillosa was also active against S. aureus. Some of the remaining extracts showed thinning of growth while others did not inhibit the growth of any of the test microorganisms Three species of seaweeds collected from Cancabato Bay, Tacloban, Leyte were processed and assayed for antibacterial activity using the filter disk-agar diffusion method. Solvent combination of the methanol and chloroform extracts of the algae were tested against P. aeruginosa, 6. coli, and S. aureus Cordero, Paciente Jr. A. adviser.
