为了寻找环保且无毒的防污 (AF) 涂料成分，人们对海藻天然产品进行了研究。藻类用来阻止不需要的表生的防御代谢物具有在 AF 应用中利用和使用的潜力。粗制藻类提取物可以提供具有 AF 功效的合适化合物混合物。使用基于五种海洋细菌菌株、五种浮游植物菌株和两种大型藻类的生物测定法对来自干燥和新鲜来源的大型藻类角叉菜（红藻科）的粗乙醇提取物进行测试和比较，以评估 AF 功效。藻类干燥提取物对细菌和浮游植物生长的最低抑制浓度低于新鲜来源的提取物，为25 μ g mL(-1)。大型藻类试验表明，提取物对裙带菜和石莼孢子均具有25-50 μ g mL(-1)的抗萌发活性。含有粗提取物的 AF 涂料的现场试验表明，初始 AF 效力可持续六周。 (C) 2011 Elsevier Ltd. 保留所有权利。
The search for environment-friendly and non-toxic antifouling (AF) paint components has led to the investigation of natural products from seaweeds. The defence metabolites used by algae to deter unwanted epibiosis have potential for harnessing and use in AF applications. Crude algal extracts may provide a suitable mixture of compounds with AF potency. Crude ethanol extracts of the macroalgae Chondrus crispus (Rhodophyceae), from both dried and fresh sources were tested and compared using bioassays based on five marine bacterial strains, five phytoplankton strains and two macroalgae to assess the AF efficacy. Dried extract from the algae had a lower minimum inhibitory concentration at 25 mu g mL(-1) against the growth of bacteria and phytoplankton species than that from the fresh source. Macroalgae tests indicated that the extracts had an anti-germination activity 25-50 mu g mL(-1) against both Undaria pinnatifida and Ulva intestinalis spores. A field trial of AF paint incorporating crude extract indicated an initial AF potency lasting six weeks. (C) 2011 Elsevier Ltd. All rights reserved.
