The seaweed (Halimeda tuna) was examined for antibacterial and antifungal activity in vitro using the well diffusion method, minimum inhibitory concentration, minimum bactericidal concentration and minimum fungicidal concentration. The activity was against 10 bacterial strains ( Staphylococcus aureus, Salmonella typhimurium, Salmonella paratyphi, Klebsiella oxytoca, Escherichia coli, Proteus mirabillis, Lactobacillus vulgaris, Pseudomonas sp., Klebsiella pneumonia and Vibrio cholerae ) and nine fungal strains ( Aspergillus niger, Aspergillus flavus, Alternaria alternaria, Candida albicans, Epidermophyton floccossum, Trichophyton mentagrophytes, Trichophyton rubrum, Pencillium sp. and Rhizopus sp.). The methanolic extracts in the present study exhibited a broad spectrum of antimicrobial activity compared to the ethanolic and chloroform extracts. Results of the present study confirm the potential use of seaweed extracts as a source of antimicrobial compound. Keywords : Halimeda tuna , minimum inhibitory concentration, minimum bactericidal concentration, minimum fungicidal concentration, antimicrobial activity African Journal of Biotechnology Vol. 12(3), pp. 284-289
