This strain exhibits positive chemotaxis towards caffeine (1,3,7\u2010trimethylxanthine) in swarm plate assay and modified capillary assay in a dose dependant manner. Related methylxanthines and xanthine also act as chemoattractants for the strain with the highest relative chemotactic response (RCR) seen for xanthine. Chemotaxis in <jats:italic>Pseudomonas <\/jats:italic> sp. is possibly plasmid mediated as indicated by positive chemotaxis of plasmid transformed <jats:italic>E. coli<\/jats:italic> DH5\u03b1. The chemotactic abilities of <jats:italic>Pseudomonas<\/jats:italic> sp. combined with higher rates of degradation of caffeine can be used in the development of strategies for biodecaffeination of caffeine containing wastes.
