“…Bacteria from the genus Comamonas have been associated with the aerobic degradation of sulfated and sulfonated surfactants (Matcham et al 1977 ; Taranova et al 2004 ; Weiss et al 2012 ), but no growth was observed during the anoxic incubation of the type strain C. denitrificans DSM 17887 T with SLES. The ability of Alicycliphilus to degrade surfactants was also never shown.…”

The surfactant sodium lauryl ether sulfate (SLES) is widely used in the composition of detergents and frequently ends up in wastewater treatment plants (WWTPs). While aerobic SLES degradation is well studied, little is known about the fate of this compound in anoxic environments, such as denitrification tanks of WWTPs, nor about the bacteria involved in the anoxic biodegradation. Here, we used SLES as sole carbon and energy source, at concentrations ranging from 50 to 1000 mg L−1, to enrich and isolate nitrate-reducing bacteria from activated sludge of a WWTP with the anaerobic-anoxic-oxic (A2/O) concept. In the 50 mg L−1 enrichment, Comamonas (50%), Pseudomonas (24%), and Alicycliphilus (12%) were present at higher relative abundance, while Pseudomonas (53%) became dominant in the 1000 mg L−1 enrichment. Aeromonas hydrophila strain S7, Pseudomonas stutzeri strain S8, and Pseudomonas nitroreducens strain S11 were isolated from the enriched cultures. Under denitrifying conditions, strains S8 and S11 degraded 500 mg L−1 SLES in less than 1 day, while strain S7 required more than 6 days. Strains S8 and S11 also showed a remarkable resistance to SLES, being able to grow and reduce nitrate with SLES concentrations up to 40 g L−1. Strain S11 turned out to be the best anoxic SLES degrader, degrading up to 41% of 500 mg L−1. The comparison between SLES anoxic and oxic degradation by strain S11 revealed differences in SLES cleavage, degradation, and sulfate accumulation; both ester and ether cleavage were probably employed in SLES anoxic degradation by strain S11.Electronic supplementary materialThe online version of this article (doi:10.1007/s00253-017-8212-x) contains supplementary material, which is available to authorized users.

“…Recently, enzymatic biosensor (tyrosinase) was applied for the detection of BPA , 17-b-estradiol (Notsu et al, 2002), PAH (Fahnrich et al, 2003) and surfactants (Taranova et al, 2004). Optical biosensors with high sensitivity (up to ng range) were successfully used for the monitoring of pesticides, EDCs, and surfactants (Skladal, 1999;Tschmelak et al, 2006).…”

“…Organic pollutants like pesticides, polychlorinated biphenyls (PCBs), and surfactants can be rapidly and efficiently determined through immunochemistry (Farré et al, 2007). The detection limits were reported to be sub-ng/L (Taranova et al, 2004). Automated optical immunosensors have been used to detect many organic pollutants including estrone, progesterone, and testosterone in water samples.…”

“…The substrate specificities of the biosensor in question towards a range of organic compounds-surfactants, polyaromatic hydrocarbons, carbohydrates, and alcohols-were studied. As was demonstrated, characteristic of the biosensor involving C. testosteroni TI was the absence of a sensitivity to glucose, which is an advantage compared with the biosensor described above based on P. rathonis T. Signals of the former sensor remained stable over 10 days of continuous measurements [19].…”

High specificity and sensitivity are characteristic of immunosensors; however, the assay time presents a certain limitation in immunoassay detection. Considering possible methods of shortening the assay time, we proposed and experimentally realized a new type of immunosensor detection. This method was tested by the Abstract -Results of the research performed at the Institute of Biochemistry and Physiology of Microorganisms, Russian Academy of Sciences, on designing immunobiosensors for detection of toxic compounds and microbial cells, enzyme-based biosensors for detection of hydrocarbons and alcohols, and microbial biosensors for aromatic compounds, surfactants, and biological oxygen consumption are reviewed. Parameters of the mediator electrodes involving microbial cells and data on the properties of microbial biofuel cells-devices based on the biosensor principle and representing alternative sources of electric energy-are presented.
