The interactions of mono-rhamnolipids (mono-RLs) with model membranes were investigated through a biomimetic approach using phospholipid-based liposomes immobilized on gold substrate and also by the multiparametric surface plasmon resonance (MP-SPR) technique. Biotinylated bound onto an SPR chip coated streptavidin layer. resulting MP-SPR signal proved efficient binding liposomes. thickness lip...

Polyhydroxyalkanoates (PHA) producers have been found in a variety of ecological niche’s that are naturally or unintentionally exposed to high organic matter growth limiting substances such as dairy wastes, hydrocarbon contaminated sites, pulp and paper mill agricultural activated sludges treatment plants, rhizosphere, industrial effluents. Few them also create extracellular byproducts rhamnoli...

Recent studies of self-assembly in binary systems bio-surfactants, either microbial origin or saponins extracted from plants, are reviewed. Saponins water reported the first section include aescin, glycyrrhizin, and quillaja saponins, while rhamnolipids discussed second on surfactants. Studies surface activities a natural starting point characterization surfactants, but here we focus mainly phy...

This study isolated a novel halotolerant Pseudomonas aeruginosa M4, that was able to degrade oil and produce rhamnolipids. Various carbon sources, nitrogen inoculum ratio, pH, temperature were tested optimize the degradation conditions. The highest rate of 85.20% lipase activity 23.86 U/mL obtained under optimal conditions (5% at 35 °C pH 8). components products different times analyzed explore...
