Pseudomonas sp. Strain WBC-3 utilized methyl parathion or para-nitrophenol (PNP) as the sole source of carbon, nitrogen, andenergy, and methyl parathion hydrolase had been previously characterized. Its chemotactic behaviors to aromatics were investigated.The results indicated that strain WBC-3 was attracted to multiple aromatic compounds, including metabolizable or transformablesubstrates PNP, 4-nitrocatehol, and hydroquinone. Disruption of PNP catabolic genes had no effect on its chemotactic behaviors with the same substrates, indicating that the chemotactic response in this swain was metabolism-independent. Furthermore, it was shownthat strain WBC-3 had a constitutive β-ketoadipate chemotaxis system that responded to a broad range of aromatic compounds, whichwas different from the inducible β-ketoadipate chemotaxis described in other Pseudomonas signs.
