Rhamnolipid CMC prediction

Journal of Colloid and Interface Science, 2017
Relationships between the purity, pH, hydrophobicity (logKow) of the carbon substrate, and the critical micelle concentration (CMC) of rhamnolipid type biosurfactants (RL) were investigated using a quantitative structure-property relationship (QSPR) approach and are presented here for the first time.

Characterisation of Pseudomonas rhamnolipids

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1990
The Gram negative organism, Pseudomonas aeruginosa, is often found in the lungs of patients with cystic fibrosis and other forms of severe bronchiectasis, where it secretes a number of extracellular toxins including the mono- and dirhamnolipids. The principal monorhamnolipid from P.

Production of rhamnolipid biosurfactants

1995
Biosurfactants are of increasing interest due to their broad range of potential applications. A large variety of microbial surfactants is known at present, some of which may be used for specific applications. Towards the large scale industrial production of biosurfactants, the physiology, biochemistry and genetics of biosurfactant synthesis has to be ...

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.

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

Production of rhamnolipids by Pseudomonas aeruginosa

Applied Microbiology and Biotechnology, 2005
Pseudomonas 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 ...
