Anti-microbial activity of aqueous extracts from selected Philippine soft coral species [Undergraduate thesis, University of the Philippines Visayas].

The aqueous extract was assayed for anti- microbial activity. Potent extracts were tested for its minimal inhibitory concentration against the most sensitive microorganisms. The equivalent potency was also determined using PEN VK as the standard antibiotic. <i>Lobophyton</i> was found to inhibit <i>S. aureus</i> at 50% concentration of the aqueous extract (ATCC 25923) while <i>Sinuloria. sp.</i> was found to inhibit the growth of both <i>S. aureus</i> (ATCC 25923) and <i>B. subtilis</i> (NSRI-1). Aqueous extracts of <i>Lobophyton sp.</i>has an equipotency of 6.64 units/ml of PEN VK against S. aureus, whereas aqueous extracts of <i>Sinulcria sp.</i> has a potency of 104 units/ml of PEN VK against <i>B. subtilis.</i>x, 45 p.Soft coralTaklong IslandGuimarasPotent extractAqueous extractLG 993.5 1994 B5 A38ThesiscoralsextractsantimicrobialsSDG 14 - Life below water
