[Chemical composition and role of Pseudomonas aeruginosa peptidoglycolipid in hydrocarbon assimilation].

Pseudomonas aeruginosa P-20 releases a lipophilic compound during growth in a medium with hexadecane. The compound was shown to be a peptidoglycolipid. The peptide moiety consists of 7 amino acids: lysine, aspartic and glutamic acids, serine, proline, valine and leucine. The carbohydrate component is ramnose. The lipid moiety is represented by a mixture of fatty acids with the number of carbon atoms from 11 to 18 among which C11:1, C16:0, C18:1 and C17:3 predominate. The content of unsaturated acids is 64.62%. The peptidoglycolipid stimulates the process of hydrocarbon assimilation.
