As previously reported, free organisms of Escherichia coli are sensitive to damage and killing when exposed to acrylic acid in water. The effect of the agent was greatest in distilled water, but there was a marked effect in effluent and seawater also. The effect was temperature-dependent, with organisms exposed at 4 degrees C being much less affected than those exposed at 20 degrees C. The above sensitivity was for free organisms, but those attached to glass beads were resistant to acrylate. This resistance applied equally to attached plasmid-free and attached plasmid-bearing organisms, but is likely to be more significant for plasmid-bearing strains because some plasmids studied here stimulated bacterial attachment. The likely significance of the acrylate resistance of attached organisms for enterobacterial survival in the aquatic environment, e.g. in the vicinity of shellfish beds, is discussed.
如先前报道，大肠杆菌的游离菌在水中接触丙烯酸时对损伤和杀灭敏感。该药剂在蒸馏水中的效果最佳，但在废水和海水中也有显著效果。其效果取决于温度，4℃下暴露的菌比20℃下暴露的菌受影响小得多。上述敏感性针对的是游离菌，但附着在玻璃珠上的菌对丙烯酸酯具有抗性。这种抗性同样适用于附着的无质粒菌和携带质粒的菌，但对于携带质粒的菌株可能更显著，因为这里研究的一些质粒促进了细菌附着。文中讨论了附着菌对丙烯酸酯的抗性对水生环境（如贝类床附近）中肠杆菌存活的潜在重要性。
