Inactivation of enveloped viruses (VSV, SFV, and SHV-1) by surfactin lipopeptides was dependent on the hydrophobicity, i.e. the number of carbon atoms of the fatty acid, and on the charge of the peptide moiety as well as on the virus species. Surfactins with fatty acid chains of 13 carbon atoms showed very low antiviral activity in comparison to C14 and C15(More)
