Fig. 6From: Characterisation and antimicrobial activity of biosurfactant extracts produced by Bacillus amyloliquefaciens and Pseudomonas aeruginosa isolated from a wastewater treatment plantExamples of the ESI–MS mass spectra of major rhamnolipid groups detected with UPLC–MS (dRL1-2 and mRL1-2). Mass spectra were generated with MaxEnt 3. Refer to Table 4 for identities of dRL1-2 and mRL1-2 and expected m/z and M r valuesBack to article page
