Biofouling is a phenomenon affecting all the infrastructures immerged in marine and freshwater environments. This colonization leads to a deterioration of the surfaces implied and affects the performances of the different structures as the decrease of ship speed or the increase of fuel consumption. Polemics around harmful antifouling coatings being more and more concerning, an alternative to toxic compounds is here proposed. The effect of three different zeolites, pure or copper loaded, is evaluated on two fouling diatoms, Cylindrotheca closterium and Amphora sp. These organisms display different sensitivities to copper usually used in antifouling paint. Finally, it has been shown that pure zeolites had stimulating effect on microalgae growth while copper loaded ones seemed efficient to inhibit their development. However, natural zeolite appeared less effective than the two synthetic after 7 days incubation. These differences seemed to be due to the bonds created by copper in the materials and to the leaching of metallic ions. Finally, the constant release of active agent in the medium by the minerals appeared to be the key for an interesting application in antifouling systems.

生物污损现象影响着浸入海洋和淡水环境的所有基础设施。这种殖民化导致所暗示的表面变质，并随着船速的降低或燃料消耗的增加而影响不同结构的性能。关于有害防污涂料的问题越来越引起人们的关注，在此提出了有毒化合物的替代方案。对两种污垢硅藻Cylindrotheca closterium和Amphora评估了三种纯沸石或铜加载沸石的作用sp。这些生物对防污涂料中通常使用的铜表现出不同的敏感性。最后，已证明纯沸石对微藻的生长具有刺激作用，而铜负载的沸石似乎能有效抑制其生长。然而，在孵育7天后，天然沸石似乎不如两种合成沸石有效。这些差异似乎是由于铜在材料中形成的键以及金属离子的浸出所致。最后，矿物质在介质中不断释放活性剂似乎是防污系统中有趣应用的关键。
