摘要
海洋污着生物附着生长在船底、海上工程设施的表面,给人类在海上的经济活动造成巨大损失。长期以来,防除海洋污着生物的主要措施是涂覆含毒物的防污漆。毒物主要是铜、汞、砷和锡的化合物,通过漆膜的慢性渗出,毒杀污着生物的幼虫或孢子。有毒防污漆虽然有效,但却日益污染海洋生态环境。70年代初有人报导了无毒防污漆的设想与研究,即防污漆未必杀死污着生物的幼虫或孢子,却能阻止其附着。当物体浸没入海水以后,细菌首先附着在物体的表面上并生长繁殖,然后硅藻、真菌、原生动物及其他微型藻类相继附着,形成一层微生物粘膜。
Two species of Thiobacillus were isolated from biofilm on pillings at Qingdao Harbour. They were identified as Thiobacillus thiooxidans and T. thioparus. The bacteria of Thiobacillus were immobilized and used in an antifouling paint. The paint has been proved to be able to prevent attachment of the large organisms. The advantage of using this paint is that it does not contain toxic substances.
