| Abstract |
Algae have long been used for the treatment of various types of diseases. Ulva lactuca is one of the algae, which contains bioactive substances as antimicrobial, antifungal, and antioxidant. This study aims to determine the microorganisms growth inhibitory activity from Ulva lactuca algae obtained from the of Lembeh Strait waters in City of Bitung against microorganisms Escherichia coli, Staphylococcus aureus and Candida albicans. Ulva lactuca algae was extracted using maceration method with ethanol solvent and fractionated with methanol, n-hexan and chloroform solvents. Testing of antimicrobial activity using agar diffusion method. The result showed that extracts and fractions of Ulva lactuca algae did not have antimicrobial activity against the microorganisms Escherichia coli, Staphylococcus aureus and Candida albicans. The chemical composition of algae is influenced by season, geographical distribution, as well as environmental factors such as temperature, water, salinity, light, nutrition, and mineral availability. |
