“…Biodegradation of anionic surfactant under aerobic conditions by the bacterium Pseudomonas sp. strain C12B was among the first to be studied (Payne and Feisal 1963), and to date quite a number of SDS-degrading bacteria have been isolated and characterized (Thomas and White 1990;Lee et al 1995;Kostal et al 1998;Roig et al 1998;Dhouib et al 2003;Ke et al 2003;Yin et al 2005;Wu 2006;Khleifat et al 2010;Asok and Jisha 2013;Kumar 2013,2014;Cortés-Lorenzo et al 2013;Venkatesh 2013;Yilmaz and Icgen 2014). Works on coldadapted microbes with ability to degrade SDS are rare, and were first reported by Margesin and Schinner (1998).The existence of multitude of bacteria with detergent-degrading ability makes bioremediation the more ideal method for detergent degradation.…”

Pollution as a result of anthropogenic activities is a severe global issue. These activities including inappropriate disposal, industrial and prospecting activities and unnecessary use of agricultural chemicals have triggered international initiatives to eliminate these contaminants. In this work we screen the ability of a molybdenum-reducing bacterium isolated from contaminated soil to grow and reduce molybdenum on various detergents. The bacterium was able to grow on SDS as a carbon source although the compound did not support molybdenum reduction. The bacterium reduces molybdate to Mo-blue optimally between pH 5.8 and 6.3 and between 25 and 34 o C. Glucose was the best electron donor for supporting molybdate reduction followed by sucrose, D-mannitol, D-sorbitol, lactose, salicin, trehalose, maltose and myo-Inositol in descending order. Other requirements include a phosphate concentration between 5.0 and 7.5 mM and a molybdate concentration between 5 and 20 mM. The absorption spectrum of the Mo-blue produced was similar to previous Mo-reducing bacterium, and closely resembles a reduced phosphomolybdate. Molybdenum reduction was inhibited by mercury (ii), silver (i) and copper (ii) at 2 ppm by 62.1, 33.9 and 33.6%, respectively. Biochemical analysis resulted in a tentative identification of the bacterium as Klebsiella oxytoca strain Aft-7. The ability of this bacterium to detoxify molybdenum and degrade detergent makes this bacterium an important tool for bioremediation.

“…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.

“…It has been suggested that this genus degrades surfactants. When used, in a reactor, they have been immobilized on different support materials such as polyacrylamide gels (Thomas and White, 1991), glass (Jerabkova et al, 1999), or polyurethane foam (Roig et al, 1999). Kertesz et al (1994) used Pseudomonas putida S-313 in a sulfatefree medium with sulfonate as the sole source of sulfur.…”
