Chemotaxis of Pseudomonas spp. to the polyaromatic hydrocarbon naphthalene

Article Abstract:

A study was conducted on the chemotaxis of naphthalene-degrading bacteria Pseudomonas sp strain NCIB 9816-4 and Pseudomonas putida G7. A modified capillary assay and a drop assay were employed to test the bacteria's chemotactical attraction to naphthalene. Biphenyl was found to be a chemoattractant to Pseudomonas putida G7. Results also show that both Pseudomonas strains were not chemotactic to other polyaromatic hydrocarbons.
