Abstract
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.
