“…Total degradation of sulfate esters was observed within 48 h and an encouraging residual activity of 13 % was retained after 13 days of use (Thomas and White 1991). Further whole cell experiments with Pseudomonas C12B and Comamonas terrigena N3H were performed on various supports to evaluate their applicability as biofilms in wastewater treatment plants (Roig et al 1998a, b). While C. terrigena N3H did not exhibit activity towards SDS, Pseudomonas C12B, which is a well known SDS-degrader (Dodgson et al 1982), was also able hydrolyse the surfactant in immobilized form (Roig et al 1998a; Thomas and White 1990).…”

This review gives an overview on the occurrence of sulfatases in Prokaryota, Eukaryota and Archaea. The mechanism of enzymes acting with retention or inversion of configuration during sulfate ester hydrolysis is discussed taking two complementary examples. Methods for the discovery of novel alkyl sulfatases are described by way of sequence-based search and enzyme induction. A comprehensive list of organisms with their respective substrate scope regarding prim- and sec-alkyl sulfate esters allows to assess the capabilities and limitations of various biocatalysts employed as whole cell systems or as purified enzymes with respect to their activities and enantioselectivities. Methods for immobilization and selectivity enhancement by addition of metal ions or organic (co)solvents are summarised.

“…Effective use of immobilized cells of Pseudomonas C12 B on porous glass beads with either unmodifi ed or silanized surface in a bioreactor showed 85 % SDS removal effi ciency (Roig et al 1998 ). The removal of SDS from synthetic wastewater in an Intermittent Cycle Extended Aeration System (ICEAS) resulted in more than 98 % removal of SDS (Mortazavi et al 2008 ).…”
