“…It has been shown that several bacteria, especially from the genera Pseudomonas, are able to biodegrade SDS through desulfation and further assimilation (Thomas and White, 1989;Kahnert and Kertesz, 2000). The important decrease in biodegradation rate for SDS, at higher concentration (1.41 g l À1 ) than its CMC, is in agreement with the results obtained by other authors (Abboud et al, 2007). From the results (Table 1), biodegradation rates reveal that the microbial degradation of the new PCL-surfactants takes place efficiently when the surfactant concentration exceeds the critical micellar concentration.…”

“…5b). Similar inhibition was observed at higher concentrations of SDS but under higher biomass levels (Abboud et al, 2007) and explained by the increase in permeability (Lamaza et al, 1991) and alteration of the hydrophobicity (Marchesi et al, 1994) of the membrane cell that induce anionic surfactants at higher concentration. These changes seem to correlate with their biodegradation capacity.…”

a b s t r a c t New amphiphilic block surfactants ABA based on a central segment of polycaprolactone with different molecular composition were evaluated in the bioremediation of naphthalene in water by Sphingomonas paucimobilis and compared with sodium dodecyl sulphate as reference surfactant (SDS). Also the biodegradation of the new surfactants by bacteria, S. paucimobilis and a mixture of bacteria (Pseudomonas aureginosa, Bacillus subtilis, Bacillus amyloliquefaciens and Bacillus megaterium) was studied by indirect impedance technique and carbon dioxide determination. All the bacteria biodegraded in solution and micellar phase the central segment of PCL with mineralization rates in the range of 0.024-0.036 mg of CO 2 per day. S. paucimobilis biodegraded naphthalene in the presence of the new surfactants and GC analysis demonstrated that conversion to products started immediately after inoculum. In all the experiments, except for SDS, at 140 h of incubation time, the remaining naphthalene concentration was about 10% of the initial concentration. In contrast, the production of CO 2 was delayed 4-7 days and values around 75%of naphthalene mineralization degree were achieved in three weeks. The addition of PCL-surfactants, in solution and in micellar phase, not interfered in the naphthalene mineralization. These results have shown promising potential of these biodegradable PCL-surfactants in surfactant-enhanced remediation (SER) technology for removing residual organics from contaminated groundwater and soils.

“…High rate of SDS degradation was observed in later stages which might be due to low levels of glucose in the culture medium. Similar reports have been made by Abboud et al [23] in a mixed consortium of Acinetobacter calcoaceticus and Pantoea agglomerans. In their study, significant reduction in SDS degradation was observed in presence of carbon sources such as glucose, sucrose, and maltose respectively.…”

Sodium dodecyl sulfate (SDS) is one of the most commonly used detergent, which exhibits excellent biocidal activity against various bacteria and fungi. It is commonly employed in many detergent formulations and is employed for disinfection purposes. It is shown to be toxic to fishes, aquatic animals and is also inhibitory to microbes and cyanobacteria. We had isolated a strain belonging to Pseudomonas aeruginosa N1, from a detergent contaminated pond situated in Varanasi city India, which was able to degrade and metabolize SDS as a source of carbon. In the present investigation, we have studied chemotactic response of this strain towards SDS. The results clearly indicate that this strain showed chemotactic response towards SDS. The nature of chemotaxis was found to be metabolism dependent as glucose grown cells showed a delayed chemotactic response towards SDS. This is first study that reported chemotaxis response for P. aeruginosa towards anionic detergent SDS.
