​Abstract

​Antimicrobial activity for pathogenic microbes is ubiquitous and is the main cause of human health problem issues. In medicine various preventive and curative interventions have been adopted. Development of synthetic and natural drugs is one of the critical ways to treat the human health problems. Ulva lactuca is macroalgae grows on rocks and form stable, multi-layered and perennial vegetation. U. lactuca has been reported as a potent source of antimicrobial and antitumor agent. Antibacterial activity of extracted product was observed. The zone of inhibition observed after 24 h for B. subtilis was 15 mm. The zone of inhibition observed after 24 h for Klebsiella pneumoniae was 13 mm. These results confirmed that the extract of U. lactuca has good antibacterial property.

Keywords: Antimicrobial activity; Ulva lactuca; Macroalgae; Zone of inhibition.
