摘要：

Twenty-seven species of common seaweeds from the coast of Korea have been screened for antifouling activity. The seaweed extracts were tested in laboratory assays against the marine fouling green alga Enteromorpha prolifera and the blue mussel Mytilus edulis. Tissue growth, spore settlement, zygote formation and germlings of the E. prolifera were inhibited by methanol extracts of the seaweed Ishige sinicola (= I. foliacea) and Sargassum horneri. Spore settlement was strongly inhibited by using extract concentrations as low as 30 μg mL-1 with I. sinicola and 120 μg mL-1 with S. horneri. The repulsive activity of the foot of the mussel was completely inhibited by methanol extracts of I. sinicola and Scytosiphon lomentaria at concentrations of 40 μg per 10 μL drop supplied to each mussel. These extracts also showed strong antifouling activities on larval settlement with, respectively, no or only 6% of the spat settling when a test concentration of 0.8 mg mL-1 was used. This work is the first stage towards the development of novel antifouling agents from marine macroalgae.
