Iturin A and surfactin are two lipopeptides extracted from a same strain of Bacillus subtilis. Iturin A possesses antibiotic and antifungal activities and surfactin is a strong surfactant. The presence of surfactin, at a concentration at which, alone, it is inactive, increases to a very large extent the haemolysis percent induced by iturin A.

Molecular mechanism of membrane permeabilization by the peptide antibiotic surfactin
Biochimica Et Biophysica Acta - Biomembranes, 2003 Surfactin, an acidic lipopeptide produced by various strains of Bacillus subtilis, behaves as a very powerful biosurfactant and possesses several other interesting biological activities.

Synthesis of Aza-Surfactin and 3-Epi-Aza-Surfactin
HETEROCYCLES, 2012Two synthetic approaches to aza surfactins are reported. In the first our recently developed synthesis of unnatural ß3 amino acids was used to prepare the requisite monomer which was used in solid phase peptide synthesis and followed by macrolactamization of a partially protected precursor. In the second the corresponding ß3 N hydroxyaminoacid was used

Interfacial properties of surfactin
Journal of Colloid and Interface Science, 1992Abstract Surfactin is a lipopeptide produced by various strains of Bacillus subtilis and is a very powerful surfactant. Here we present the first report on the interfacial behavior of surfactin. The adsorption, Γmax, of surfactin at the interface of diluted solutions (5 × 10−8 to 5 × 10−7M) is around 3 × 1018 molecule m−2, a value indicating that ...

Hydrolysis of surfactin over activated carbon
Bioorganic Chemistry, 2019Surfactin is obtained through biocatalysis by microorganisms. In our biorefinery concept, it is purified on activated carbon (AC) during downstream processing. Besides cyclic surfactin, it is possible to obtain linear surfactin analogues, when AC with specific properties is used.

Structural Diversity of the Microbial Surfactin Derivatives from Selective Esterification Approach
International Journal of Molecular Sciences, 2015 Surfactin originated from genus Bacillus is composed of a heptapeptide moiety bonded to the carboxyl and hydroxyl groups of a β-hydroxy fatty acid and it can be chemically modified to prepare the derivatives with different structures, owing to the ...
