Ecklonia cava is commonly used as foodstuff and 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 extend the usage of E. cava residue, microbial fermentation was performed. The microbial fermentation of the residue may result in the breakdown of bioactive compounds or the production of bioactive compounds. As expected, the methanolic extract of E. cava residue fermented by Candida utillis showed strong antibacterial activity against several pathogenic bacteria. The antibacterial activity was
higher than that of the extract of raw E. cava residue. Our finding may contribute to the development of a natural antibiotic agent using the seaweed waste.
