Chemotaxis Behavior Of Pseudomonas Species And Biodegradation Of Pollutants

Chemotaxis in Pseudomonas species is one of the most diversified and best-understood signal transduction network. Most strains possess one or two sets of the chemotaxis genes. They have the ability to sense changes in the concentration of chemicals in the environment and respond by altering their pattern of motility using the two chemotaxis pathways. The flagella-mediated pathway and the pili-mediated system are involved in bioremediation, pathogenesis and plant protection. Although a large number of Pseudomonas species have chemotaxis abilities, only seven species have had their chemotaxis abilities screened. P. aeruginosa is now considered as a model organism for the study of chemotaxis systems. This chapter reviews chemotaxis and biodegradation in Pseudomonas species.
