Production of rhamnolipids by Pseudomonas aeruginosa
Applied Microbiology and Biotechnology, 2005Pseudomonas aeruginosa produces glycolipidic surface-active molecules (rhamnolipids) which have potential biotechnological applications. Rhamnolipids are produced by P. aeruginosa in a concerted manner with different virulence-associated traits. Here, we review the rhamnolipids biosynthetic pathway, showing that it has metabolic links with numerous ...

Environmental Applications of Rhamnolipids
2018Environmental pollution due to industrial pollutant has become a serious problem of recent time. Hence, their management is of immense concern. Various technologies have been put forward in the last few decades and are being employed but most of them are not economically feasible while some result in incomplete removal of pollutants or in formation of ...

Foliar penetration enhanced by biosurfactant rhamnolipid
Colloids and Surfaces B: Biointerfaces, 2016With recent environmental and health concerns, biosurfactants have obtained increasing interest in replacing conventional surfactants for diverse applications. In agriculture, the use of surfactant in stimulating foliar uptake is mainly for wetting leaf surface, resisting deposition/evaporation, enhancing penetration across cuticular membrane (CM) and ...

Rhamnolipid biosurfactant behavior in solutions
Journal of Biomaterials Science, Polymer Edition, 2004The solution behavior of rhamnolipid biosurfactant that is determined by its surface thermodynamic properties often plays a central role in determining and controlling its performance in practical applications. In this study, rhamnolipid molecules exhibited a predominant hydrophilic surface, contributed by hydrophilic monomer head groups.

Several microorganisms are known to produce a wide variety of surface-active substances, which are referred to as biosurfactants. Interesting examples for biosurfactants are rhamnolipids, glycolipids mainly known from Pseudomonas aeruginosa produced during cultivation on different substrates like vegetable oils, sugars, glycerol or hydrocarbons ...

Wetting characteristics of aqueous rhamnolipids solutions
Colloids and Surfaces B: Biointerfaces, 2004The wetting properties of surfactants on solid surfaces form the basis of many industrial and biological processes. The preferential adsorption of the surfactants from aqueous solutions onto solid surfaces alter the adhesion tension of the surface and this behavior may cause partial to complete wetting of the surfaces by the aqueous surfactant ...

Pseudomonas aeruginosa is an environmental bacterium that can be isolated from many different habitats including water, soil and plants, but it is also an opportunistic human pathogen causing serious nosocomial infections8. Under specific environmental conditions this bacterium produces and secretes rhamnose-containing glycolipid biosurfactants.

Biosurfactant-rhamnolipid effects on yeast cells
Letters in Applied Microbiology, 2001The aim of this work was to study the effect of the novel surfactant PS from Pseudomonas sp. S-17 on Saccharomyces cerevisiae 83-20 yeast cells and to compare it with the effect of the well known surfactant Triton X-100.The effect of surfactants was investigated on the cells during growth, and on the separated cells.

Solubilization of n-alkanes by dirhamnolipid (diRL) biosurfactant at sub-critical micelle concentrations (sub-CMC) was studied and the results were compared to that for monorhamnolipid (monoRL) obtained in our prior study. The results show that the apparent solubility of the four alkanes (decane, dodecane, tetradecane and hexadecane) increases linearly
