Structure and characterization of flavolipids, a novel class of biosurfactants produced by Flavobacterium sp. strain MTN11
Article Abstract:
Research describes the production of flavolipids by a soil bacterium Flavobacterium sp. strain MTN11. Flavolipids range from 584 to 686 in molecular weight and contain a polar moiety made of citric acid and two cadaverine molecules. The critical micelle concentration of 300 milligram per liter and a low surface tension of 26.o mN/m suggest that flavolipids possess strong surfactant activity.

A rhamnolipid biosurfactant reduces cadmium toxicity during naphthalene biodegradation
Article Abstract:
Results show that the metal-complexing biosurfactant rhamnolipid reduces cadmium toxicity in a concentration dependent manner. Data indicate that rhamnolipid at 10 times the cadmium concentration, totally eliminates the toxicity whereas at equimolar concentration it only reduces the toxicity and no effect at all with 10-fold less concentration.

Rhamnolipid-induced removal of lipopolysaccharide from Pseudomonas aeruginosa: effect on cell surface properties and interaction with hydrophobic substrates
Article Abstract:
Biosurfactants appear to make the cell surface of Pseudomonas aeruginosa become more hydrophobic by causing the release of lipopolysaccharide. Biosurfactants can increase the ability of bacteria to degrade hydrocarbons.
