Abstract:
:A chemotaxis system for Pseudomonas aeruginosa was defined by using the method of Adler. Cells were attracted to compounds in the order ammonium chloride greater than amino acids greater than organic acids. Two sugars were assayed and elicited no response. Comparisons with other model systems are discussed.
