Production of rhamnolipid biosurfactants
1995Biosurfactants 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 ...

Rhamnolipid biosurfactant mixtures for environmental remediation
Water Research, 2008This study investigated the efficiency of rhamnolipid biosurfactant and synthetic surfactant mixtures for improving the interfacial activity of the surfactant system against several light non-aqueous-phase liquids (LNAPLs). Since the rhamnolipid biosurfactant proved to be relatively hydrophilic, we hypothesized that mixtures of rhamnolipid ...

Why do microorganisms produce rhamnolipids? [PDF]
World Journal of Microbiology and Biotechnology, 2011 We review the environmental role of rhamnolipids in terms of microbial life and activity. A large number of previous research supports the idea that these glycolipids mediate the uptake of hydrophobic substrates by bacterial cells. This feature might be of highest priority for bioremediation of spilled hydrocarbons.

Abstract Rhamnolipids (RMLs) have more effectiveness for specific uses according to their homologue proportions. Thus, the novelty of this work was to compare mono‐RMLs and di‐RMLs physicochemical properties on microbial enhanced oil recovery (MEOR) applications. For this, RML produced by three strains of

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 ...
