1. SULFOCHLORINATION WITH SULFURYL CHLORIDE : AN ALTERNATIVE PROCESS FOR THE MANUFACTURE OF SECONDARY ALKANESULFONATES / SULFOCHLORATION PAR LE CHLORURE DE SULFURYLE : UN PROCEDE ALTERNATIF POUR LA FABRICATION D ALCANESULFONATES SECONDAIRES.
Secondary alkanesulfonates (SAS) are biodegradable surfactants largely used as active matter in detergent formulations and as emulsifying agents. SAS are manufactured by photosulfoxidation or photosulfochlorination of linear paraffin cuts. The photosulfochlorination process usually involves the reaction of a gas mixture (SO 2 + Cl 2) on alkanes, but recent w

2. Deletion Analysis of the Escherichia coli Taurine and Alkanesulfonate Transport Systems
The Escherichia coli tauABCD and ssuEADCB gene clusters are required for the utilization of taurine and alkanesulfonates as sulfur sources and are expressed only under conditions of sulfate or cysteine starvation. tauD and ssuD encode an α-ketoglutarate-dependent taurine dioxygenase and a reduced flavin mononucleotide-dependent alkanesulfonate monooxygenase

3. A Novel Reduced Flavin Mononucleotide-Dependent Methanesulfonate Sulfonatase Encoded by the Sulfur-Regulated msu Operon of Pseudomonas aeruginosa
When Pseudomonas aeruginosa is grown with organosulfur compounds as sulfur sources, it synthesizes a set of proteins whose synthesis is repressed in the presence of sulfate, cysteine, or thiocyanate (so-called sulfate starvation-induced proteins). The gene encoding one of these proteins, PA13, was isolated from a cosmid library of P. aeruginosa PAO1 and sequ

4. Taurine reduction in anaerobic respiration of Bilophila wadsworthia RZATAU.
Organosulfonates are important natural and man-made compounds, but until recently (T. J. Lie, T. Pitta, E. R. Leadbetter, W. Godchaux III, and J. R. Leadbetter. Arch. Microbiol. 166:204-210, 1996), they were not believed to be dissimilated under anoxic conditions. We also chose to test whether alkane- and arenesulfonates could serve as electron sinks in resp
