The effect of different concentrations of the anionic surfactant sodium dodecyl sulfate (SDS) on biodegradation of diesel oil was assessed during 32 days at 10 degrees C, under simulated environmental conditions, in liquid culture and in an alpine soil. Low SDS concentrations (50-100 mg l-1) significantly enhanced oil biodegradation by a psychrotrophic inoculum in liquid culture, whereas higher...

The color of squaraine solution shows a "fingerprint" change upon addition of different surfactants. A cross-responsive sensing array based on a small molecular probe was applied to discriminate surfactants with 100% confidence limits. Furthermore, the probe can selectively detect sodium dodecyl sulfate (SDS) with turn-on fluorescence response.

The protein composition of Escherichia coli W3110 grown in the presence and absence of 5% sodium dodecyl sulfate (SDS) was examined by two-dimensional gel electrophoresis. In SDS-grown cells, at least 4 proteins were turned on, 13 were turned off, 15 were elevated, and 15 were depressed. The 19 unique and elevated SDS-induced spots constituted 7.91% of the total 35S-labeled protein. There was n...

conclusions the findings of this study showed that the modification of natural zeolites can achieve higher adsorption capacity for organics. in addition, based on the results, natural zeolite being modified with sds as a cationic surfactant had good efficiency for the adsorption of nom. results the results indicated that sds-modified zeolite showed greatly enhanced adsorption capacity. findings...

Sodium dodecyl sulfate (SDS) and other alkyl sulfates, provided they contain a minimum of 12 carbon atoms (or 322 A in length), stabilize mouse interferon (MIF) in the presence of urea, 2-mercaptoethanol, and heat. When MIF is treated with the alkyl sulfates in the absence of urea and 2-mercaptoethanol, all alkyl sulfates inactivate MIF to the same extent. This suggests that the stabilizing eff...

The purpose of this work was the fabrication a conductive carbon nanotube (CNT) ink. proposed CNT ink remained remarkably stable over several months. method includes combining covalent and non-covalent functionalization, resulting in that exhibits excellent storage stability. functionalization performed acid medium using H2SO4 HNO3, while used sodium dodecyl sulfate (SDS) ultrasonication. mater...

The effect of surfactant concentration and film area on film stability was investigated in thin liquid films of sodium dodecyl sulfate (SDS) solutions. Film stability was evaluated at various concentrations of SDS solutions and various film areas. In this study, a maximum film stability was observed for the SDS concentration of 200 mM. Interestingly, this concentration also corresponds to the m...
