The assimilation of sulfur from multiple sources and its correlation with expression of the sulfate-starvation-induced stimulon in Pseudomonas putida S-313
Article Abstract:
The growth kinetics of Pseudomonas putida in the presence of a single source of sulfur or of pairs of sources are described. An exponential growth of P. Putida with sulfate as the sole source of sulfur was observed, with growth concomitant with the utilization of sulfur until its depletion. After the exhaustion of sulfate, some 20% more protein was synthesized. P. Putida also grew exponentially with 4-toluenesulfonate (Ts), although minimal protein formation after the depletion of Ts was observed. Findings with 4-nitrocatecholsulfate and ethanesulfonate were similar.

Regulation of the sulfate starvation response in Pseudomonas aeruginosa: role of cysteine biosynthetic intermediates
Article Abstract:
The PAO1 strain of Pseudomonas aeruginosa contains 10 sulfate starvation-inducible proteins that are upregulated in conditions of sulfate limitation based on two-dimensional gel electrophoresis. Eight of these proteins do not show any similarity to other proteins induced by sulfate starvation previously identified and characterized indicating that these enzymes are unique sulfur scavengers. Repression analyses showed that the genes coding for sulfate starvation response are downregulated by two or more independent corepressors.

Degradative pathways for p-toluenecarboxylate and p-toluenesulfonate and their multicomponent oxygenases in Comamonas testosteroni strains PSB-4 and T-2
Article Abstract:
The three multicomponent oxygenases implicated in the degradation of p-toluenesulfonate and p-toluenecarboxylate and the regulation of their synthesis have been studied in three strains (T-2, PSB-4 and TER-1) of Comamonas testosteroni. Strain T-2 uses p-toluenesulfonate as source of carbon and energy for growth. PSB-4 uses only sulfobenzoate and terephthalate via protocatechuate. TER-1 uses only terephthalate via protocatechuate.
