Ecklonia cava is commonly used as foodstuff, pharmaceutical and nutraceutical materials. The residue of E. cava, which is a by-product of the seaweed products, has been dispose as a fertilizer or an industrial waste. However, we expect that the seaweed residue still contains many of bioactive compounds in the tissue. In order to reuse the residue, new approach using microbial fermentation was performed. The microbial fermentation of the residue may result in the break-down of bioactive compounds or the production of bioactive compounds. As expected, the methanolic extract of E. cava residue fermented by Aspergillus oryzae showed strong antibacterial activity against several pathogenic bacteria.The antibacterial activity was higher than that of the extract of raw E. cava. Our finding may contribute to the development of a natural antibiotic agent using the seaweed waste.
