Absorption of a Multicomponent Rhamnolipid Surfactant to Soil
Article Abstract:
Batch and column studies using two sandy soils to investigate the absorption of the multicomponent biosurfactant rhamnolipid, which may have applications in soil remediation. The authors conclude absorption of rhamnolipid to soil is mainly an interfacial process.

Effects of rhamnolipid biosurfactants on removal of phenanthrene from soil
Article Abstract:
The effectivity of the action of a biosurfactant in removing phenanthrene from a soil column was shown to be improved with the addition of rhamnolipid with a concentration of 500mg per liter. Time required for the 50% removal of phenanthrene in soils were found to be shorter by two to five times compared to the use of the surfactant alone, while 90% removal was found to be 3.5 times lower with the addition of rhamnolipid in the surfactant. The enhancing effect of rhamnolipid is theorized to be related to its ability to enhance micellar solubilization and sorption kinetics.

Effects of rhamnolipid biosurfactants on removal of phenanthrene from soil
Article Abstract:
Rhamnolipid biosurfactants enhance the removal of phenantrene from soil mainly through micellar solubization and also by influencing sorption kinetics, according to Dutch researchers. Removal of phenantrene, a hydrophobic organic contaminant, was accomplished 3.5 times faster when a rhamnolipid-containing electrolyte solution was used as compared with the treatment without rhamnolipid. The study used soil columns contaminated with phenantrene and determined the effectiveness of rhanolipid biosurfactants by using a 500g/L rhanolipid electrolyte solution.
