液滴法和改良毛细管法测定了恶臭假单胞菌G7和NCIB假单胞菌9816-4对萘的化学吸附。在萘或水杨酸盐上生长诱导趋化反应。恶臭假单胞菌G7对联苯也有趋化作用；其他被测试的多芳香烃似乎并不是这两种假单胞菌菌株的化学引诱剂。经萘降解质粒固化的菌株对萘不产生吸附。
Two naphthalene-degrading bacteria, Pseudomonas putida G7 and Pseudomonas sp. strain NCIB 9816-4, were chemotactically attracted to naphthalene in drop assays and modified capillary assays. Growth on naphthalene or salicylate induced the chemotactic response. P. putida G7 was also chemotactic to biphenyl; other polyaromatic hydrocarbons that were tested did not appear to be chemoattractants for either Pseudomonas strain. Strains that were cured of the naphthalene degradation plasmid were not attracted to naphthalene.
