JACQUES, Rodrigo J. S. et al. Mass spectrometry analysis of surface tension reducing substances produced by a pah-degrading Pseudomonas citronellolis strain. Braz. J. Microbiol. [online]. 2008, vol.39, n.2, pp.353-356. ISSN 1517-8382.

In this work we investigated the structure of the iron-stimulated surface tension reducing substances produced by P. citronellolis 222A isolated from a 17-years old landfarming used for sludge treatment in petrochemical industries and oil refinery. Its mass spectrum differs from P. aeruginosa spectrum, indicating that the surface tension reducing substances produced by P. citronellolis can be a new kind of biosurfactant.

Keywords : Pseudomonas aeruginosa; rhamnolipid mixture; ESI mass spectrum; biosurfactant.
