The chemotactic response is inducible, and a regulatory mutant strain that forms the β-ketoadipate transport system at high levels exhibits a heightened chemotactic response to β-ketoadipate. Adipate and succinate, compounds that interact with the transport system, inhibit chemotaxis toward β-ketoadipate. Some, but not all, mutants that fail to respond chemotactically to β-ketoadipate lack the β-ketoadipate transport system. It thus appears that the transport of β-ketoadipate is associated with its function as a chemoattractant. It is likely that the metabolite attracts fluorescent Pseudomonas species to environments in which complex aromatic polymers undergo microbial dissimilation. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-124-1-25
