Mass spectrometric study of rhamnolipid biosurfactant suggested that the formation of stable supramolecule complexes of rhamnolipids with membrane phospholipids is a possible molecular mechanism of their antimicrobial activity (samadi, abadian et al 2012. To try and identify the characteristics of the biosurfactant which are antibacterial mass spectrometry will be used to examine the effects of the biosurfactants on the metabolome of the treated bacteria and on the materials leaking from the damaged cells.
