| Since the past, seaweeds have been utilized as food and medicine for its curative properties. Given the biological activities of seaweeds numerous studies have been executed particularly in macro algae, but still are far away of it pharmacological application. For this work, the seaweeds were collected in the reef areas of La Parguera, Lajas Puerto Rico, after washing and grinding them we proceed to the extraction using organic solvents in a proportional mix 2:1 of chloroform and methanol. Employing rotoevaporation the liposoluble extracts of the algae was separated from the organic solvents. The liposoluble extracts were maculated in bacterial cultures, two Gram(+):Bacillus subtilis, Staphylococcus aureus and two Gram(-):Pseudomona aeroginosa and Echerichia coli, to compare its bacterial inhibition with Erythromycin and Ampiciline. The results demonstrated that the inhibition varies depending of the type of seaweed and bacteria. It has been noted that there is also a stationary effect with the inhibition that is probably related with the seaweeds reproduction cycle. |
