New Recombinant Production of Design Rhamnolipids – Optimized Biosurfactant Fermentation Process

Genetically modified non-pathogenic host cell to produce favoured rhamnolipids in high yields

Biosurfactants have attracted increasing interest since they show a number of advantages over surfactants of petrochemical origin in terms of ecological acceptance, low toxicity and sustainability.Biosurfactants also have a huge application potential, for example in chemical and pharmaceutical industry or as emulsifier in cosmetics and foods.

Among the best established biosurfactants are the rhamnolipids. Rhamnolipids are glycosides with one (mono-rhamnolipid) or two rhamnose-units (di-rhamno-lipid) as the glycon portion and one to three β-hydroxy-fatty acid moieties as the aglycon portion.
