Improvement on stability, loading capacity and sustained release of rhamnolipids modified curcumin liposomes.

Colloids and Surfaces B: Biointerfaces, 2019
A novel cholesterol-free curcumin delivery system was fabricated by rhamnolipids modified liposomes (RL-Lps). The incorporation of the rhamnolipids increased the sphericity, reduced the size, and decreased the polydispersity of the liposomes compared ...

Immobilization of Ni (Ⅱ) at three levels of contaminated soil by rhamnolipids modified nano zero valent iron (RL@nZVI): Effects and mechanisms.

Chemosphere, 2021
A kind of biosurfactant rhamnolipid modified zero-valent iron nanoparticles have been synthesized and applied to evaluate the immobilization efficiency of Ni (Ⅱ) contaminated soil at three concentration levels (200Ni, 600Ni and 1800Ni).

Production of Rhamnolipids

2018
Presently, more concern is being paid towards compilation of various strategies and conditions for rhamnolipids biosurfactant production. The present chapter emphasizes the various strategies and conditions for biosurfactant production including rhamnolipids which are the major class of biosurfactants.

Complexation of Cadmium by a Rhamnolipid Biosurfactant

Environmental Science & Technology, 1994
The potential of microbially-produced surfactants (biosurfactants) to complex heavy metals was investigated in this study. Batch solution studies using a model metal, cadmium, and an anionic monorhamnolipid biosurfactant produced by Pseudomonas aeruginosa ATCC 9027 showed that complexation of the metal and biosurfactantwas rapid and stable and achieved

The true methodology for rhamnolipid: Various solvents affect rhamnolipid characteristics

European Journal of Lipid Science and Technology, 2017
Rhamnolipid, among the most effective biosurfactants, is a glycolipid‐type biosurfactant primarily produced by Pseudomonas aeruginosa. In this study, rhamnolipid production was carried out using a strain of P. aeruginosa and it is aimed to compare rhamnolipid biopolymers obtained from various extraction methods using glycine (RG), hydrochloric acid (RH)

Purification and characterization of the biosurfactant rhamnolipid

Chinese Journal of Chromatography, 2014
Biosurfactant rhamnolipid is a metabolic intermediate produced by microorganisms under a certain condition. There are the polar hydrophilic group and the non-polar hydrophobic group in rhamnolipid molecule which always exhibits high surface or interfacial activity.

Rhamnolipids—Next generation surfactants?

Journal of Biotechnology, 2012
The demand for bio-based processes and materials in the petrochemical industry has significantly increased during the last decade because of the expected running out of petroleum. This trend can be ascribed to three main causes: (1) the increased use of renewable resources for chemical synthesis of already established product classes, (2) the ...

Formulating Alcohol‐Free Microemulsions Using Rhamnolipid Biosurfactant and Rhamnolipid Mixtures

Journal of Surfactants and Detergents, 2008
AbstractThis research focused on developing alcohol‐free biosurfactant‐based microemulsions. Rhamnolipid‐based mixtures were found to have double the solubilization parameter as compared to sodium bis(2‐ethyl) dihexyl sulfosuccinate/sodium dihexyl sulfosuccinate/sodium mono‐ and dimethyl naphthalene sulfonate at the same total molar concentration.
