Abstract Pseudomonas aeruginosa PAO1 used a broad range of alkanesulfonic acids as sole sulfur source for growth, with molar growth yields of 2.2 to 2.9 kg protein per mol sulfur. 4-Phenylbutane-1-sulfonate was desulfonated in vivo to yield 4-pheny 1-1-butyric acid quantitatively as the sole product, suggesting that the desulfonation mechanism is the same as when alkanesulfonates serve as a carbon source for growth. This contrasts with aromatic sulfonate utilization in other organisms, where different desulfonation reactions are used to provide carbon and sulfur. Desulfonation of alkanesulfonates to provide sulfur was repressed by sulfate or thiocyanate, and derepressed in their absence. The alkanesulfonatase system is hence controlled as part of the sulfate starvation-induced stimulon.
