Biocatalytic desulfurization of arylsulfonates

Bioorganic & Medicinal Chemistry, 1994
A microbial strain, Klebsiella oxytoca KS3D, has been isolated which is capable of exploiting arylsulfonates as a sole source of sulfur during growth. The desulfurization catalyzed by intact K. oxytoca KS3D results in the conversion of arylsulfonates into the corresponding phenols.
