Separation and Characterization of Surfactin Isoforms Produced by Bacillus subtilis OKB 105

Abstract

Natural surfactin is a mixture of cyclic lipopeptides built from variants of a heptapeptide and a beta-hydroxy fatty acid with chain lengths of 13-15 carbon atoms. The lipopeptide biosurfactant was produced by Bacillus subtilis OKB 105 and part of the material subjected to esterification of its Glu and Asp residues. High-resolution preparative reversed… (More)
