Review of surfactin chemical properties and the potential biomedical applications

Abstract

Surfactin, a highly powerful biosurfactant produced by various strains of the genus Bacillus, exhibits antibacterial, antiviral, antitumor and hemolytic action. This anionic cyclic lipopeptide is constituted by a heptapeptide interlinked with a β-hydroxy fatty acid. Due to its amhipathic nature surfactin incorporates into the phospholipid bilayer and induces permeabilization and perturbation of target cells. The rising antibiotic resistance as well as a number of remarkable surfactin activities shows that it deserves special interest and is considered as a candidate compound for combating several health related issues. In this review, the current state of knowledge of surfactin properties, biomedical potential and limitations for its application is presented. © 2008 Versita Warsaw and Springer-Verlag.
