Triton X-100 (TX-100), a useful non-ionic surfactant, reduced the methicillin resistance in Staphylococcus aureus significantly. Many S. aureus proteins were expressed in the presence of TX-100. SarA, one of the TX-100-induced proteins, acts as a global virulence regulator in S. aureus. To understand the effects of TX-100 on the structure, and function of SarA, a recombinant S. aureus SarA (rSa...

Bioremediation approaches for the treatment of oily sludge from a refinery were evaluated using a 2(3) factorial design. The three strategies tested were bioaugmentation with indigenous microbial consortia (MO) isolated from oily sludge, biostimulation with nutrients (NP) and biostimulation with the surfactant Triton X-100 (TX). Eight experimental runs were conducted in triplicate with factor s...

A two phases process consisting of a soya lecithin (SL)-based soil washing process followed by the photocatalytic treatment of resulting effluents was developed and applied at the laboratory scale in the remediation of an actual-site soil historically contaminated by 0.65 g/kg of polychlorinated biphenyls (PCBs). Triton X-100 (TX) was employed in the same process as a control surfactant. SL and...

Direct determination of the adsorbed amounts of surfactants on AgI by IR-spectroscopy is described. The adsorbed quantities are determined from the relationship between the intensities of the characteristic bands in IR-spectra of standard samples and the samples with adsorbed surfactants. The samples for IR-measurements are in the form of patterns consisting of AgI separated from the systems. T...

We previously reported that Triton X-100 (TRX) reduced methicillin resistance in Staphylococcus aureus, although the degree of reduction varied among strains. One of the biological effects of TRX on S. aureus cells was enhancement of lipoteichoic acid (LTA) release. We investigated the correlation between the amount of LTA released and the degree of reduction in methicillin resistance induced b...
