Objective:To evaluate the antimicrobial activity ofTurbinaria conoides(T. conoides), Padina gymnospora (P. gymnospora) andSargassum tenerrimum against human bacterial and fungal pathogens.Methods: The antimicrobial activities of the extracts against various organisms were tested by using disc diffusion method.Results:The methanol extract showed the better result than the other extracts. Whereas, the strong antibacterial inhibition was noted in methanol extracts ofP. gymnospora againstBacillus subtilus (26.33±1.86)and the mild inhibition of ethanol extracts fromT. conoides againstKlebsiella pneumoniae (2.33±0.51). Acetone extraction ofP. gymnospora had strong antifungal inhibition againstCryptococcus neoformans(23.00±1.78), and acetone extract ofT. conoides had mild inhibition againstAspergillus niger(3.00±0.89). Conclusions:The seven different solvent extracts of seaweeds used in the present study have shown significant bacterial action. Further, a detailed study on the principle compound in the seaweeds which is responsible for antimicrobial activity is still needed and it can be achieved by using advanced separation techniques.
