Antichaotropic salts, such as magnesium sulfate, and metal chelators, such as citrate ions, promoted adsorption of bacteriophage MS2 to membrane filters. In contrast, compounds that disrupt hydrophobic interactions, such as chaotropic salts, urea, Tween 80, and ethanol, did not promote adsorption of MS2 to membrane filters and counteracted the ability of magnesium sulfate to promote such adsorption. These results provide evidence that magnesium sulfate promotes the association of MS2 with membrane filters primarily by strengthening hydrophobic interactions between the virus and the filters.
抗促变盐类，如硫酸镁，以及金属螯合剂，如柠檬酸根离子，可促进噬菌体MS2吸附到膜滤器上。相比之下，破坏疏水相互作用的化合物，如促变盐类、尿素、吐温80和乙醇，则不会促进MS2吸附到膜滤器上，反而会抵消硫酸镁促进这种吸附的能力。这些结果表明，硫酸镁主要通过加强病毒与滤器之间的疏水相互作用来促进MS2与膜滤器的结合。
