From birth to health, surfactants play an essential role in our lives. Due to the importance, their environmental impacts are well understood. One of the aspects that has been extensively studied is their impact on bacteria, particularly on their motility. Here, we uncover an alternate chemotactic strategy triggered by surfactantsdiffusiophoresis. We show that even a trace amount of ionic surfactants, down to a single ppm level, can promote the bacterial diffusiophoresis by boosting the surface charge of the cells. Because diffusiophoresis is driven by the surface–solute interactions, surfactant-enhanced diffusiophoresis is observed regardless of the types of bacteria. Whether Gram-positive or -negative, flagellated or nonflagellated, the surfactants enable fast migration of freely suspended bacteria, suggesting a ubiquitous locomotion mechanism that has been largely overlooked. We also demonstrate the implication of surfactant-enhanced bacterial diffusiophoresis on the rapid formation of biofilms in flow networks, suggesting environmental and biomedical implications.

“…Numerous studies have revealed that nonionic surfactants, such as the polyoxyethylene octyl phenols (e.g. the Triton X series), do not have any negative effects on the oil quality [54][55][56] . The amount of Triton X-100 was 50 wt.% of each nanoparticle.…”

this study compares the tribological and thermophysical features of the lubricating oil using MoS 2 and Zno nano-additives. the average size of MoS 2 and ZnO nanoparticles were 90 nm and 30 nm, respectively. The nanoparticles were suspended using Triton X-100 in three different concentrations (0.1, 0.4 and 0.7 wt.%) in a commercial diesel oil. Tribological properties such as mass loss of the pins, friction coefficient, and worn surface morphologies and thermophysical properties such as viscosity, viscosity index, flash point and pour point of resulting nano lubricant were evaluated and compared with those of pure diesel oil. the tribological behavior of nano lubricants was evaluated using a pin-ondisc tribometer. the worn surface morphologies were observed by scanning electron microscopy. the overall results of this experiment reveal that the addition of nano-MoS 2 reduces the mass loss values of the pins in 93% due to the nano-MoS 2 lubricant effect. With 0.7 wt.% in nanoparticles content, the viscosity of MoS 2 and ZnO nano lubricants at 100 °C increased by about 9.58% and 10.14%, respectively. Pure oil containing 0.7 wt.% of each nanoparticle increased the flash point because of its small size and surface modifying behavior compared to the pure oil. Moreover, the addition of Zno nanoparticles with pure oil lubricant is more suitable than MoS 2 nanoparticles for improving the thermophysical properties of pure oil.

“…Chemical structure of Triton X-100 is shown in Figure 1. It is widely used as a solubilizer, detergent, or dispersing or wetting agent due to its chemical stability, good wettability, and low toxicity [20,21]. Interestingly, our previous research showed that Triton X-100 could accelerate the bioleaching rate of chalcopyrite, though it has a detrimental impact on ferrous-oxidizing activity of bioleaching microorganisms [22].…”

Enhancing the Leaching of Chalcopyrite Using Acidithiobacillus ferrooxidans under the Induction of Surfactant Triton X-100

et al. 2018

Chalcopyrite is the richest copper sulfide mineral in the world, but it is also the most resistant to biohydrometallurgical processing. To promote the bioleaching of chalcopyrite, a nonionic surfactant, t-octyl phenoxy polyethoxy ethanol (Triton X-100), was employed in this paper. Action of Triton X-100 in chalcopyrite leaching using Acidithiobacillus ferrooxidans was explored in shake flasks. Results showed that 30 mg·L−1 of Triton X-100 increased the bioleaching yield of copper by 42.21% compared to the process without additive after 24 days. Under the stress of Triton X-100, the bioleaching efficiency of chalcopyrite slightly dropped at an early stage, but remarkably increased afterwards. XRD and XPS analysis of the leach residues demonstrated that potassium jarosite and elemental sulfur resulted in surface leaching passivation. Surfactant Triton X-100 appeared to induce the oxidation of elemental sulfur by bacteria owing to the increase in the sulfur surface hydrophobicity. These results suggest that Triton X-100 itself has no ability to leach chalcopyrite, but under its induction, the bioleaching of chalcopyrite can be enhanced due to the removal of the passivation layer.
