Surfactant/biosurfactant mixing: Adsorption of saponin/nonionic surfactant mixtures at the air-water interface

pH effects on the molecular structure and charging state of β-Escin biosurfactants at the air-water interface

“…[12] On one hand, the interfacial and bulk structure e.g. of escin has been well established by small-angle X-ray scattering, [13,14] neutron reflectometry [7,15,16] as well as by molecular dynamic simulation. [9,17] On the other hand, this is different for the interfacial charging state of saponins e.g.…”

Studies on evaluation of surfactant coupled sonication pretreatment on Ulva fasciata (marine macroalgae) for enhanced biohydrogen production

“…The surfactant was coupled with sonication to enhance the biopolymer release of the macroalgae and the energy spent for sonication can be reduced. The action of surfactant causes a decrease in surface tension and the surface area of the particle increases [54] . The combined treatment enhances the cavitation process leading to the faster release of organic compounds into the system.…”

Neutron reflection and the thermodynamics of the air–water interface

“…The important theme of the nature of the mixing of biosurfactants with conventional surfactants was continued in a recent study involving a rather different biosurfactant, the saponin, escin. Tucker et al 120 used NR to study the mixing of escin with the nonionic surfactants C 12 E 5 and C 12 E 8 at the air–water interface. Here the NR measurements are more challenging because only the conventional surfactants can be readily deuterium labelled, but it was still possible to determine the surface composition because the scattering length of escin is just sufficiently large enough without deuteration.…”
