Negative Chemotaxis of Marine Bacteria to Toxic Chemicals

L. Y. Young1 and Ralph Mitchell

a Division of Engineering and Applied Physics, Harvard University, Cambridge, Massachusetts 02138

ABSTRACT

The positive chemotactic responses of motile marine bacteria were reversed by the addition of sublethal concentrations of a toxic chemical. The negative chemotactic effect was observed with a wide range of toxicants including heavy metals and hydrocarbons. This phenomenon may be utilized to develop new approaches for control of marine fouling.
