Abstract:
The antibacterial activity of crude extracts from red seaweed Tricleocarpa fragilis was obtained with different organic solvents were evaluated against five pathogens Staphylococcus aureus, Pseudomonas aeruginosa, Listeria monocytogenes, Bacillus cereus and Salmonella enterica typhimurium by agar well diffusion method. The results revealed that crude extracts obtained by chloroform had inhibiting effect on the growth of all tested pathogens. But the maximum zone of inhibition (21 ± 0.1mm) was obtained with acetone extracts against S. aureus. Whereas minimum zone of inhibition (5 ± 0.3mm) was observed with the hexane extracts against B. cerus. But crude extracts with chloroform exhibited inhibiting effect on all the pathogens. The positive control with azithromycin showed inhibitory action against all the pathogens studied. Present results suggested that the bioactive compounds extracted from red seaweeds using chloroform as a solvent could be a major source for developing antibacterial compounds.
