摘要
The microbial lipopeptides, which is an important kind of biosurfactants, possesses powerful surface activities and peculiar biological properties. The primary structure of the lipopeptides is mainly composed of a hydrophilic peptide moiety and a hydrophobic alkyl chain. Because of its chemical composition and amphiphilic behavior, the lipopeptides can be exploited in many fields such as pharmaceutics, food and cosmetic industries, environmental remediation and oil recovery. The surfactin, primarily renowned for its exceptional surface activities as well as biological properties, is one of the most active microbial lipopeptides. Surface-active and biological properties mainly occur at interfaces and are governed by the conformational state of molecules at hydrophobic/hydrophilic interfaces. This paper reviews the recent progress in molecular behavior of microbial lipopeptides represented by surfactin at the air/water interface.
