Abstract

Biosurfactants, surface active molecules synthesized by microorganisms, represent a promising alternative to the synthetic surfactants in many different applications. Among them, rhamnolipids have attracted considerable attention in the last years due to their extraordinary surface-active properties and biological activities. Rhamnolipids are usually synthesized by the gram-negative bacterium Pseudomonas aeruginosa as complex mixtures of different congeners. In this chapter, we describe the most common techniques that can be used for the production, recovery and purification of rhamnolipids, using two sequential chromatographic techniques to recover and separate the monorhamnolipid and dirhamnolipid congeners.

Keywords: Adsorption chromatography; Biosurfactant; Orcinol; Pseudomonas aeruginosa; Rhamnolipid; Silica gel; Surfactant.
