Anti-Fouling Exopolysaccharides Isolated from Cultures of Vibrio Alginolyticus and Vibrio Proteolyticus一種海洋弧線菌產生的無毒性抗污損天然化合物

總結: It is well known that growth of micro-organisms or macrofouling matters on the submerged parts of a structure may have detrimental effects on their operation and their corrosion rate.

A method of preventing fouling of aquatic surfaces by organisms is invented. It does not contaminate the environment to the extent contamination occurred using previous anti-fouling methods. It concerns a bacterial product with antifouling properties against larvae of dominant marine fouling organisms which therefore avoids such organisms from blooming on surfaces with these compounds. In suspension culture, this bacterium releases compounds of high molecular weight that can be harvested by ultrafiltration. This high molecular weight fraction exhibits prominent antifouling activity against fouling organisms on global scale. The antifouling effect has been demonstrated to be non-toxic to the target organisms and is reversible in the absence of the agent.

技術優勢: 1. Non-toxic, reversible and does not bioaccumulate
2. Relatively easy to obtain government approval due to its environmental friendliness
3. Can be generated biotechnologically in large scale using commercially available technology

技術應用: - Non-toxic antifouling products for Shipping industries, Marine paint manufacturers, pipelines, oil platforms, ocean-going vessels, equipment for use under the sea
