Sodium dodecyl sulfate (SDS) is one of the most commonly used detergent, which exhibits excellent biocidal activity against various bacteria and fungi. It is commonly employed in many detergent formulations and is employed for disinfection purposes. It is shown to be toxic to fishes, aquatic animals and is also inhibitory to microbes and cyanobacteria. We had isolated a strain belonging to Pseudomonas aeruginosa N1, from a detergent contaminated pond situated in Varanasi city India, which was able to degrade and metabolize SDS as a source of carbon. In the present investigation, we have studied chemotactic response of this strain towards SDS. The results clearly indicate that this strain showed chemotactic response towards SDS. The nature of chemotaxis was found to be metabolism dependent as glucose grown cells showed a delayed chemotactic response towards SDS. This is first study that reported chemotaxis response for P. aeruginosa towards anionic detergent SDS.
十二烷基硫酸钠（SDS）是最常用的清洁剂之一，对各种细菌和真菌表现出优异的杀菌活性。它广泛应用于许多清洁剂配方中，并用于消毒目的。它对鱼类、水生动物有毒，对微生物和蓝藻也有抑制作用。我们从印度瓦拉纳西市的一个受洗涤剂污染的池塘中分离到一株属于铜绿假单胞菌 N1 的菌株，它能够降解和代谢 SDS 作为碳源。在本研究中，我们研究了该菌株对 SDS 的趋化反应。结果清楚地表明，该菌株对 SDS 表现出趋化反应。趋化性的性质被发现是代谢依赖性的，因为葡萄糖生长的细胞对 SDS 表现出延迟的趋化反应。这是首次报道铜绿假单胞菌对阴离子洗涤剂 SDS 的趋化反应。
