The potential on N-vanillylnonanamide (NVN) in preventing the attachment of Pseudomonas stutzeri and a Bacillus cereus-group strain was investigated. NVN up to 852 microM was not toxic, nor was it an energy source for either organism. Microbial attachment assays were carried out on glass and polylysine slides. with NVN being dispersed in or applied to the surfaces using a polyurethane coating. NVN at 205 microM inhibited Bacillus adhesion on glass slides by 48% and the percentage did not significantly increase at 852 microM. NVN blended into or sprayed onto the coating at 205 micromol/kg did not prevent adhesion. The compound is therefore not useful as an antifouling product under the tested coating conditions.
研究了N-香草基壬酰胺（NVN）在防止斯氏假单胞菌和蜡状芽孢杆菌属菌株附着方面的潜力。高达852微摩尔的NVN无毒，也不是这两种微生物的能量来源。在玻璃和聚赖氨酸载玻片上进行了微生物附着试验，NVN通过聚氨酯涂层分散在表面或应用于表面。205微摩尔的NVN可使玻璃载玻片上芽孢杆菌的附着力降低48%，在852微摩尔时该百分比没有显著增加。以205微摩尔/千克混入或喷涂到涂层中的NVN并不能防止附着。因此，在测试的涂层条件下，该化合物作为防污产品没有用处。
