Is rhamnolipid biosurfactant useful in cadmium phytoextraction?

, 2010
Purpose: Successful chelant-assisted phytoextraction requires application of an eco-friendly metal-complexing agent which enhances metal uptake but does not pose a significant risk of off-site movement of metals.

Experimental Investigations of Behaviour of Biosurfactants in Brine Solutions Relevant to Hydrocarbon Reservoirs

Colloids and Interfaces, 2019
In this study, we investigated the behaviour of rhamnolipid and Greenzyme in brine solutions relevant to hydrocarbon reservoir. Prior to this work, several studies only reported the behaviour of the biosurfactants dissolved in sodium chloride solutions ...

Effect of MA01 rhamnolipid on cell viability and expression of quorum-sensing (QS) genes involved in biofilm formation by methicillin-resistant Staphylococcus aureus

Scientific Reports, 2022
A group of biosurfactants, called rhamnolipids, have been shown to have antibacterial and antibiofilm activity against multidrug-resistant bacteria. Here, we examined the effect of rhamnolipid biosurfactants extracted from Pseudomonas aeruginosa MA01 on ...

Biosurfactant slows down n-hexadecane biodegradation: 13C-labeled rhamnolipid tracing

Ecotoxicology and Environmental Safety
Rhamnolipids are globally applied in bioremediation, but their specific metabolic fate and regulatory mechanisms remain unclear. This study addresses this gap by using 13C stable isotope technology to trace rhamnolipid partitioning and evaluate its ...

Biophysical characterization of synthetic rhamnolipids [PDF]

The FEBS Journal, 2006
Synthetic rhamnolipids, derived from a natural diacylated glycolipid, RL‐2,214, produced by Burkholderia (Pseudomonas) plantarii, were analyzed biophysically. Changes in the chemical structures comprised variations in the length, the stereochemistry and numbers of the lipid chains, numbers of rhamnoses, and the occurrence of charged or neutral groups ...

Enhanced rhamnolipid production by Pseudomonas aeruginosa under phosphate limitation

, 2010
Rhamnolipid biosurfactants are effective antimicrobial agents and provide a promising alternative to synthetic medicine. Rhamnolipid accumulation by Pseudomonas aeruginosa ATCC 9027, and associated antimicrobial activity, was quantified during phosphate ...

Acidogenic fermentation of pretreated food waste under psychrophilic conditions for volatile fatty acids production

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Mixed‐culture fermentation generally produces volatile fatty acids (VFAs) as a mixture of C2–C6 acids. Among operational parameters, temperature has a distinct effect on the microorganisms' metabolic activity, which can shift the composition of the metabolites.
